  • Graduated from an accredited college of osteopathic medicine (COM)
  • Has earned a DO degree

New Eligibility Requirements

Beginning with the 2018-2019 test cycle for the two-day COMLEX-USA Level 3, eligibility will require an attestation from an American Osteopathic Association (AOA) or Accreditation Council for Graduate Medical Education (ACGME) accredited graduate medical education program director that the Level 3 resident/exam candidate is in “good academic and professional standing” meeting the professional requirements of the residency program and is eligible to continue as a resident in the program. In addition, as a recommendation but not a requirement, the NBOME recommends that Level 3 candidates have completed a minimum of six months of residency training prior to testing.
