General  Scoring  COMLEX-USA Level 3 Post-Exam Standard Setting
About the Examination Series
COMLEX-USA - the Comprehensive Osteopathic Medical Licensing Examination of the United States-is a high-quality, high-stakes, three-level medical licensing examination series for osteopathic physicians. The COMLEX-USA series emphasizes medical problem-solving knowledge and cognitive skills. It is the only licensing examination that covers osteopathic principles, practices, and the application of osteopathic manipulative treatment. The series includes three computer-based examinations:
  • COMLEX-USA Level 1-assesses the competent application of foundational and basic biomedical and osteopathic science knowledge relevant to clinical presentations as defined by the COMLEX-USA blueprint, emphasizing the scientific concepts and principles necessary for understanding the mechanisms of health, clinical problems and disease processes.
  • COMLEX-USA Level 2-Cognitive Evaluation (CE) -assesses the competent application of knowledge of clinical concepts and principles involved in all steps of clinical problem solving for osteopathic medical practice as defined by the COMLEX-USA blueprint, emphasizing the biomedical and osteopathic concepts and principles necessary for making appropriate clinical diagnoses through patient history and physical examination findings.
  • COMLEX-USA Level 3 - assesses competence in the foundational competency domains required for generalist physicians to deliver safe and effective osteopathic medical care and promote health in unsupervised clinical settings.
What do the COMLEX-USA computer-based cognitive examinations measure?
The COMLEX-USA examination series is designed to assess the osteopathic medical knowledge, knowledge fluency, and clinical skills considered essential for osteopathic generalist physicians to practice osteopathic medicine. The foundation of COMLEX-USA is based on the osteopathic philosophy of whole-person health care, underlying structure-function relationships and the interdependence of body systems, self-healing and self-regulatory mechanisms, and the full scope of the osteopathic approach to patient care,including osteopathic manipulative medicine. The COMLEX-USA Master Blueprint details the COMLEX-USA design and content coverage.
Do the computer-based examinations require substantial computer skills?
No. Research suggests that performance on computer-based tests is not related to the level of computer literacy. Substantial computer experience is not required to take the computer-based examinations. Examinees need to know only how to click the mouse to select answers or other labeled options.
What is the format of the computer-based COMLEX-USA examinations?
The COMLEX-USA Levels 1, 2-CE, and 3 examinations are computerized non-adaptive tests. The questions selected for each COMLEX-USA examination are predetermined. The number of questions and time limit for the examinations are also predetermined and under normal administration conditions are the same regardless of when and where the examinations are administered. The total number of questions for COMLEX-USA Level 1 and 2-CE is 352, and the total testing time for both exams is eight hours. The examination is divided into two sessions consisting of four sections. Refer to the COMLEX-USA Bulletin of Information for more detail specific to each Level.

Yes. Candidates are limited to a total of four attempts for each examination. Review the COMLEX-USA Bulletin of Information for details. You should also be sure to check the policies of your college of osteopathic medicine for its retake guidelines, which may differ from the NBOME's. You will need the approval of your dean or residency program director to retake the examination; however, approval to retake a COMLEX-USA examination by a dean or residency program director will not override NBOME retake policy. NOTE: Candidates may not retake any level of COMLEX-USA to improve their scores or for any purpose other than to pass a previously failed examination.
Personal Information
Is my personal information secure?
Yes. Your personal data is treated by NBOME as confidential. Your information will not be disclosed to any individual or entity without written, signed consent by you or an order of a court of competent jurisdiction.
How do I change my name in the NBOME records?
If your name has changed, download and complete a Name Change Request Form.
How do I update my contact information?
You can update your mailing address, email address, and phone numbers in your NBOME Account under the "Student Information" section on the "My Account" tab.
How do I update my medical school information?
If you transferred medical schools, you must contact the dean's office at your old and new school and request that they forward the information to NBOME Client Services.
How do I obtain my NBOME profile?
Each year, the NBOME obtains a student list from each college of osteopathic medicine. The NBOME system automatically generates and emails the access information to each candidate after validation. This typically occurs during the fall of each year. If you do not receive the code by this time, check with your college to confirm your information has been submitted to the NBOME. If you are a former osteopathic student and do not have an NBOME username and password, please contact Client Services by emailing clientservices@nbome.org or calling 866-479-6828 to set up an account. Please provide the osteopathic college you attended, the year of graduation, your date of birth, and any names you had in the past.
What browser is required to access the online system?
For candidates in a MAC environment, the NBOME recommends using Safari. For those using a PC, the NBOME recommends using Internet Explorer. The system may not run properly when using other browsers. At this time, the NBOME does not recommend accessing the online system from a mobile device because of compatibility issues.
Test Accommodations
If you are a “Person With Disability” under the Americans with Disabilities Act, and wish to receive test accommodations for an NBOME examination, review and download the following request forms and instructions document. Complete and submit the Request for Test Accommodations form with the supporting documentation substantiating your eligibility for the accommodation to NBOME Test Accomodations:
  • By Email testacc@nbome.org
  • Or By Mail NBOME Test Accommodations 101 West Elm Street Suite 230 Conshohocken, PA 19428
A completed application with full supporting documentation is generally evaluated within 60 days of its receipt by NBOME. Consult the COMLEX-USA Bulletin of Information, Accommodations section for more information.
Can I schedule a COMLEX-USA examination with a testing accommodation application pending?
Yes. You can schedule a standard (non-accommodated) examination while your application is pending. However, if your application is approved by NBOME with testing accommodations granted, and you have not yet taken the examination, you will likely need to reschedule the test depending on the nature of the approved accommodation(s). If you schedule a standard (non-accommodated) examination while your application is pending and have taken the examination without accommodations before being notified by NBOME of its decision on your request, NBOME will deem your request for an accommodation withdrawn. Also consult the COMLEX-USA Bulletin of Information, Accommodations section.
Preparing for the Examination
Can I see what the computer-based examinations look like before I take at test?
Yes, you can take practice exams on the NBOME website. Visit Practice & Preparation for each level examination. You are encouraged to review and take the practice exams before test day. Before the practice and actual examinations, a tutorial is presented before you start the test so you can familiarize yourself with the operation of the computer, the program options, and the procedures used during the examination.
  • NBOME recommends using Google Chrome to access the online practice tests
The system may not run properly when using other browsers. At this time, NBOME does not recommend accessing practice exams from a mobile device because of compatibility issues.
Does the NBOME offer any study materials for the COMLEX-USA examinations?
Yes. NBOME offers practice examinations and other preparatory resource materials on our website. Visit the COMLEX-USA Practice & Preparation page for all available COMLEX-USA related resources. In addition, the Comprehensive Osteopathic Medical Self-Assessment Examination (COMSAE) series, which was defined using the same competency-assessment framework as the COMLEX-USA series, enables you to conduct a self-assessment before taking a COMLEX-USA exam. COMSAEs are not intended to predict performance on any of the corresponding levels of COMLEX-USA. NBOME does not endorse any alternative study examinations or materials.
Can the NBOME offer any suggestions and/or materials to aid me in studying my problem areas for a retake?
If you did not pass a COMLEX-USA cognitive examination and intend to retake it, you should work alongside your college or program for suggestions or study aids. The NBOME provides the score report, and a graphical performance profile is included. This profile will help identify areas on which you may wish to focus in preparing for the retake.
Are there any breaks during the examination?
The test day for COMLEX-USA Level 1 and Level 2-CE consists of two sessions of four hours each. COMLEX-USA Level 3 is a two-day exam, which consists of four sessions of three and a half hours. Candidates are allotted 60 minutes of “pooled” break time (including time for lunch) to be utilized at scheduled section breaks however the candidate sees fit. Refer to the COMLEX-USA Bulletin of Information for more detail.
What identification do I need to present at the test center?
Acceptable forms of government ID include a passport, driver’s license, or state ID. A military ID that does not have a signature must be accompanied by a second form of ID that bears your signature.
What is an acceptable government ID?
You are required to present:
  • A current government-issued photo identification, that bears your first and last name
  • ID must match the name and signature on the registration form
  • Students whose identification does not match their registration are considered a “No Show” and deemed responsible for paying rescheduling fees
Acceptable forms of government ID include:
  • Passport
  • Driver's license, or state ID
  • A military ID with signature*
*A military ID that does not have a signature must be accompanied by a second form of ID that bears your signature.
What if my computer freezes during the examination?
You must bring the issue to the attention of a test center staff member or proctor immediately so they can reboot the computer for you. You will not lose any answers already entered, nor will you lose any examination time—the computer system stores all your answers instantly. After rebooting, the computer screen will return exactly to where you were working before the malfunction, both in terms of your responses and the time remaining in the examination.
If the issue is not resolved to your satisfaction, you must contact NBOME Client Services within 10 calendar days of the examination date and provide credible, verifiable written evidence of the adverse testing condition in order for the NBOME to investigate the incident. We will acknowledge your email in a timely manner and will then investigate and contact you with a resolution.
What should I do if I experience issues/problems during administration of my examination?
You must bring the issue to the attention of a test center staff member or proctor immediately. If the issue is not resolved to your satisfaction, you must contact NBOME Client Services within 10 calendar days of the examination date and provide credible, verifiable written evidence of the adverse testing condition in order for the NBOME to investigate the incident. We will acknowledge your email in a timely manner and will then investigate and contact you with a resolution. For more information, please reference the COMLEX-USA Bulletin of Information.
Are there any penalties for the cancellation of an examination or tardiness on the day of the exam?
If you arrive at the test center on the scheduled examination date within 30 minutes after the scheduled start time, you may be permitted to take the examination only if the test center is able to deliver the examination in its entirety. If you arrive at the test center more than 30 minutes past the scheduled start time, you may be designated as a "No Show."
You may be permitted to take the examination at the sole discretion of the proctor or testing vendor only if the test center is able to deliver it in its entirety. If you are not permitted to take the examination, you will be deemed as a "No Show" and will be responsible for the corresponding administration fee. For complete details, refer to the COMLEX-USA Bulletin of Information.
Scores and Transcripts
When and how will scores be reported?
For the COMLEX-USA Level 1 and 2-CE computer-based examinations, candidates can expect to receive test results approximately 4 to 6 weeks from the day of examination administration. (Note: the first score release of each test cycle may be subject to brief delays.) Candidates can expect to receive score reports approximately 8 to 10 weeks from the completion of the Level 3 examination (after the initial score release). You can check the dates when scores will be released under Scoring and Reporting for each COMLEX-USA examination on the website. Candidates will be notified by email that their score reports are accessible through thier NBOME Account. Candidates will be able to access the test results immediately after they are available along with their examination history.
The NBOME will also post score reports to osteopathic medical schools immediately after the results are available, and schools can access and obtain up-to-date information about their student's test-taking activities and test results at any time. For Level 3, residency program directors also received their resident score reports through CRS/Portal when the reports are released.
What types of score reports will my school and I receive from my COMLEX-USA cognitive examinations?
For COMLEX-USA Level 1, the student score report will provide a “pass/fail” designation instead of a 3-digit standard score and a pass/fail designation. For Levels 2-CE and 3, the student score report will provide 3-digit standard score and a pass/fail designation. Percentile rank will not be reported because candidates will be taking the examination throughout the year. Following completion of the annual testing cycle, you can look up your percentile rank in relation to others in the same cohort using the COMLEX-USA Percentile Score Converter. You will also be provided with a graphical performance profile according to the COMLEX-USA blueprint.
Because computer-based COMLEX-USA examinations are administered continuously throughout the year, osteopathic medical schools will receive school annual reports after the testing cycle is completed. The annual school reports include school information compared with the national performance.
Are some multiple choice questions (MCQs) weighted more than others on COMLEX-USA?
No. Every scorable test question contributes equally to the candidate's score.
A fellow student scored extremely low in one discipline area of a COMLEX-USA examination, but still passed the examination. What are the discipline scores, and how do they relate to the total COMLEX-USA score?
COMLEX-USA is an examination currently designed around competency domains and clinical presentations, not disciplines. The discipline performance profiles are provided at the request of the college of osteopathic medicine deans, American Association of Colleges of Osteopathic Medicine, and candidates to potentially assist with lifelong learning, remediation, and program evaluation.
Performance profiles should not be used to interpret areas of importance or emphasis for any particular examination. Performance profiles:
  • Are not additive for projecting the total score or pass/fail status
  • Do not contain metrics technically designed for sub-score reporting
  • Based on a relatively small number of items as compared to the total test, therefore reliability of sub-scores is lower than for the total test.
Apply caution in using performance profiles in order to avoid misinterpretation.
What are 3-digit COMLEX-USA scores?
Please note that as of May 10, 2022, COMLEX-USA Level 1 reporting transitioned from a three-digit numeric score to “Pass” or “Fail” outcomes. The minimum passing 3-digit standard score for Level 2-CE is 400, and Level 3 is 350, regardless of when the examination is taken. COMLEX-USA 3-digit scores are NOT raw scores or the number of items answered correctly. Similarly, they are NOT the percentage of items answered correctly.
Why doesn't the NBOME report COMLEX-USA percentile ranks?
A percentile score is an examinee's performance rank among a defined peer group that takes the same examination. For COMLEX-USA examinees, this peer group is considered to be the examinees who take an examination in the same testing cycle. To accurately compute a percentile score, scores of the whole cohort, or at least most of the cohort, need to be available. The testing cycle-based 3-digit scores, 2-digit scores, and percentile conversions can be found with the COMLEX-USA Percentile Score Converter.
How do I request a score confirmation, and how long does it take to receive it?
You can choose to submit a request to the NBOME for score confirmation within 120 days of the examination. Log in to your NBOME Account and select the "View Scores" tab. At the bottom of the page is the option to "Request Score Confirmation." The processing fee for score confirmations for all COMLEX-USA examinations is $75.00. This covers the cost to confirm all responses recorded during your computer-based testing. It takes up to 10 business days for Level 1 and Level 2-CE and 15 business days for Level 3 to receive a letter from NBOME with the score verification result.
Can COMLEX-USA scores be converted into United States Medical Licensing Examination (USMLE) scores so that those programs can have a common criterion to judge all applicants?
The NBOME understands the desire for a "conversion formula" for osteopathic medical students applying to ACGME-accredited residency programs. The NBOME is currently developing a study plan for the development of a valid and reliable conversion formula. Meanwhile, NBOME offers a guide to residency program directors which includes the proper use of the percentile score converter and secondary uses of COMLEX-USA exam scores.
If COMLEX-USA and USMLE scores cannot be converted, how should ACGME programs use COMLEX-USA scores to evaluate osteopathic applicants?
The NBOME encourages ACGME Residency Program Directors (RPDs) to gain a full understanding of the COMLEX-USA examination series-in particular, what it assesses, its format, and how standards are set. The NBOME provides resources for this purpose, one of which is the guide for residency progrqam directors. In addition, all residency program directors can take advantage of the percentile score converter. Note: A full testing cycle cohort must be complete before a given score can be converted.
How do I request an official transcript?
You can request an official transcript by submitting an electronic request with the appropriate fee via your NBOME Account. Individuals that do not have access to their online account may submit a written request form. Third parties that wish to request an official transcript will need to complete the transcript form and obtain a written consent from the osteopathic physician in order to receive the transcript. No request for a transcript will be taken by telephone.
What is the process time for obtaining an official transcript?
Transcript requests will be processed in the order of the date received. The normal processing time is one to two business days from the date of receipt, and three to five shipping days using standard USPS mail. Transcripts can also be sent via FedEx's overnight delivery service for an additional fee.
Can I request my transcript while I am waiting for the scores?
The NBOME can only accept and process a transcript request for examination scores which are available. If you request a transcript and a score is pending, it will not appear on your transcript. In order to process your transcript request, you must have at least one COMLEX-USA examination for which the score is available.
What should I do if my ERAS request is listed as "NOT MATCHED"?
In order for an Electronic Residency Application Service (ERAS) request to be transmitted successfully, all personal profile information in the ERAS account must match with your NBOME online account. The profile information includes your first and last name, date of birth, and NBOME ID. If the information in ERAS does not match your NBOME online account, you will see "NOT MATCHED," and the request will not be processed. In order to resolve the mismatch, you will need to correct the information with ERAS. If you have any questions, please contact NBOME Client Services and update the necessary information. You will then re-transmit the request via the ERAS application.
How do I update my ERAS request after I receive my new scores?
NBOME will send new scores upon receipt of a new ERAS request. You will use the ERAS application to request a re-transmit.
Clinical Decision-Making (CDM) Cases
What are CDM cases?
The CDM examination was first developed by the Medical Council of Canada in 1992 and has been adopted by countries across the world, including Australia and Germany. CDM cases assess the ability to make appropriate patient management decisions as an independently practicing osteopathic generalist physician. The cases are not meant to simply assess factual knowledge but rather to assess the ability to apply knowledge at specific decision points in patient care, a special emphasis for the COMLEX-USA Level 3 examination.
How are CDM cases constructed?
CDM cases focus on key, critical decisions and challenges related to patient care that are routinely faced by osteopathic generalist physicians. A typical CDM case consists of a clinical scenario followed by two to four questions. CDM cases feature two question types: constructed response (short answer) and extended multiple choice (one or more correct) questions. Test questions ask about data acquisition (e.g., obtaining history or physical exam findings, ordering tests), data interpretation (e.g., generating a diagnosis), and treatment (e.g., prescribing medication, counseling, or planning follow-up care). Follow these links for a CDM tutorial and example CDM cases.
What content is being assessed in the CDM cases?
CDM cases follow the same content blueprint as COMLEX-USA.
How should I respond to short answer questions?
Responses should be concise and limited to specific diagnoses, examination steps, diagnostic studies, or treatments. It is unnecessary to answer short answer questions with full sentences. Do not include reasoning or justifications for your responses. The short answer text boxes will only allow you to type up to 100 characters per box.
Can I use abbreviations in my answers?
It is generally advisable to avoid or limit abbreviations due to the lack of standardization. Use of abbreviations when completing short answer questions runs the risk of misinterpretation in scoring and should be used with caution. It is therefore recommended that you spell out names and terms rather than abbreviate.
Will I be penalized for misspellings?
The examination does not include a spell-check feature; however, misspellings in answers are acceptable when the meaning and interpretation are still clear. There is technically no penalty for misspelling answers unless the meaning is ambiguous or incorrect.
Can I use protocols in my answers?
Use of protocols as answers will NOT be accepted as correct because they are not universal. The necessary steps or components of protocols must be listed individually in separate boxes. For example, the answer “ACLS protocol” would not be accepted as correct when “synchronized cardioversion” is the next step.
How should I write an order as an answer?
Write the order just as you would on a hospital or urgent care order record, in specific terms that a technician, nurse, or other health care professional could understand and carry out. However, medication dosages are not required in answers.
Can I answer a question with a laboratory test that is not included on the list of approved lab panels?
Yes, you can answer with any specific test. The approved laboratory test panels are the only panels that are acceptable as answers. If the panel you have in mind is not listed in the approved lab panels list, please enter the specific test(s) that you want to order. Separate tests should each be entered in separate text boxes.
Should I repeat an answer that I already provided on a previous question within a case?
Each question will be scored separately. Your previous answers will not be taken into account in the scoring of each individual question. If you feel that the option is the appropriate answer to the question, select it again.
How will I know which medical resources are available to me in each case?
For each case, assume all necessary resources are available to you as a generalist physician in the setting described, and answer accordingly.
Can a referral be an appropriate answer to a question?
If the correct plan of action requires a specialty referral and/or consultation, you must specify the appropriate procedure or management steps in addition to the type of specialist.
Why does COMLEX-USA Level 3 have a two-day format?
In September 2018, the COMLEX-USA Level 3 examination changed to a two-day format as part of an overall enhancement of the COMLEX-USA examination series. This was in response to substantive changes in the evolution of osteopathic medical practice and to ensure COMLEX-USA remains current in meeting the needs of state licensing boards. To read more about the enhanced COMLEX-USA, you can access the COMLEX-USA Master Blueprint.
What is the attestation requirement?
Your residency program director will need to attest to the fact that you are in good academic and professional standing and are approved to take the Level 3 examination. It is recommended that you take the examination after a minimum of six months in residency.
If I contest my score, why won’t the NBOME re-grade my exam?
Prior to releasing any COMLEX-USA scores, multiple checks are done for score accuracy as well as reliability and ongoing quality assurance is performed to assure that the score accurately reflects your performance across the course of the day. The scoring process involves numerous individuals who have completed extensive training under a competence-based process.
Why doesn’t the NBOME re-mediate failures?
COMLEX-USA is a national standardized licensure examination for the practice of osteopathic medicine. It is an independent assessment of osteopathic medical knowledge, knowledge fluency, clinical skills and other competencies essential for practice as an osteopathic generalist physician and, as such, does not provide recommendations for remediation. The NBOME is a national testing organization independent of specific osteopathic medical school curriculum and we encourage all students to reach out to their school for assistance in the remediation process.
When will I receive my examination scores?
Scores are generally available within 8-10 weeks of the examination date; please see the website for score release dates. This time is required to ensure accurate, reliable and valid examination scoring and reporting. Scores are analyzed and checked for accuracy before the scores are released. There may be additional delays that are dependent on candidate testing and other variables that are not within NBOME’s control.
How can I access my examination scores?
Candidates and deans will receive an e-mail notifying them that score reports are available through your NBOME Account. A notice will also be posted via social media (Facebook and Twitter). Score reports can be accessed via CRS using your username and password. Candidates should consult the COMLEX-USA Bulletin of Information for additional information.
What is "Irregular Conduct," as annotated on the score report?
Any irregular behavior that would constitute unprofessional conduct, as outlined in the COMLEX-USA Bulletin of Information in regards to the application or registration for, the taking of, or the conduct after taking any COMLEX-USA examination series subject to NBOME's policies, could result in invalidation of an examination or disqualification.
If I failed, how do I reschedule to take the examination?
Upon receipt of a failing score, you may register for another examination through your NBOME Account. When logging into the registration program, you should have several opportunities to reschedule for the examination. If you do not see an acceptable date within 6-8 weeks or have specific questions, please call us at 1-866-479-6828 for assistance with scheduling.
When should I reschedule for the examination?
When rescheduling, be sure to allow adequate time to retake the examination prior to your school's graduation deadline, and keep in mind the time required for remediation, rescheduling, and score report release (typically 8-10 weeks).
Is there a limit on how many times I can take the COMLEX-USA examination?
Yes. Candidates taking COMLEX-USA examinations are limited to a total of four (4) attempts for each examination. Review the COMLEX-USA Bulletin of Information for details.
Standard Setting
What is standard setting?
Standard setting is a process commonly used by organizations involved with high-stakes testing. NBOME's standard-setting process ensures the standards of osteopathic medical licensure assessment reflect current medical education and medical practice.
How often are the standards changed?
The NBOME follows industry-standard best practices in establishing its schedule e.g., every three to five years for review of pass/fail standards. With the adoption of the Master Blueprint, the NBOME revisited standard setting for Level 3 in 2018 and Level 1 and Level 2-CE in 2019.  The new standards for Level 3, Level 2-CE and Level 1 are implemented in the new testing cycle – September 2018 for Level 3, May 2019 for Level 1 and June 2019 for Level 2-CE.
How does the NBOME establish the pass/fail standard for COMLEX-USA examinations?
The NBOME applies criterion-referenced methods for establishing cut scores – the score at or above which a candidate is deemed to have passed. These are sometimes referred to as "absolute standards," and are not "norm-based" or "relative" to the performance of other examinees.
A process of triangulation is used to establish cut scores. This process includes standard-setting surveys, standard-setting panel meetings, and a comprehensive final review.
For its computer-based testing examinations (e.g. COMLEX-USA Level 1, Level 2-CE, Level 3), the NBOME uses commonly-accepted standard setting methods such as the modified Angoff method. For its clinical skills assessment (COMLEX-USA Level 2-Performance Evaluation), the NBOME uses a generalized examinee-centered method – where panelists involved in the standard-setting process make judgments based on actual examinee performances across the entire range of score performances, relative to the skills being assessed.
Why are the standards periodically reviewed and changed?
The NBOME's mission is to protect the public by providing the means to assess competencies for osteopathic medicine and related health care professions. Consistent with our mission, the NBOME periodically reviews and resets pass/fail standards for COMLEX-USA to ensure the standards of osteopathic medical licensure examinations reflect current medical education and medical practice.
How does the NBOME notify the colleges, students, and other stakeholders about changes to the COMLEX-USA standards?
We use a number of outlets to inform interested parties about new standards. These include updates on the NBOME website, mailings to stakeholders (e.g. all deans), NBOME presentations to the American Association of Colleges of Osteopathic Medicine and the Council of Osteopathic Student Government Presidents, as well as updates at the annual meetings of the Assembly of Osteopathic Graduate Medical Educators, the AOA’s Leadership, Education, Advocacy & Development and the American Association of Osteopathic Examiners.
The NBOME is continuously working to improve the effectiveness of our communications regarding standards and other areas that are important to our stakeholders. You are welcome to contact us with your feedback.
Does the NBOME monitor the consequences of the new standards?
The NBOME studies test data and their consequences quite rigorously in a process of continuous quality improvement, ever guided by our mission and mandate to "protect the public."
