Percentile Scores

This content is for candidates who took the COMLEX-USA Level 2-CE before June 2019. Candidates taking the COMLEX-USA Level 2-CE beginning June 17, 2019 can view the new documentation here.

The NBOME does not report percentile scores in candidates’ score reports. Upon the completion of a testing cycle, percentile scores are estimated and can be accessed using the Percentile Score Converter. This tool converts standard scores into percentile scores for computer-based COMLEX-USA Level 1, Level 2-CE and Level 3 examinations.

How To Find Percentile Scores
  1. Open the Percentile Score Converter.
  2. Enter your three-digit standard score into the respective field.
  3. Select the examination level being converted using the drop-down menu.
  4. Select the date that the examination was taken using the drop-down menu.
  5. Click the “Convert” button.
  6. The corresponding percentile score will appear on the right.

The value calculated by the Percentile Score Converter is the percentile rank in relation to other candidates who took a particular Level examination for the first time during the same testing cycle. Percentile scores provide normative information about the relative rank of candidates’ performance in comparison to others who took the examination within the same testing cycle. Percentile scores are dependent on the population of candidates for a given year; therefore, standard scores for a given Level examination may correspond to different percentiles for different testing cycles.
