Clerkship NBME Grading Tables
2016-2017
Background
The methods for assigning final grades in clerkships for MSIII students underwent significant revision for the
2010-2011 academic year. Clerkship NBME grading was altered to set new cutoff levels for qualification for
final grades of Honors, High Pass and Fail (unchanged). Specifically, the cutoff points for these three grades
were set at the 80th, 70th and 5th percentiles, respectively. Furthermore, due to the existence of period
trends in clerkship NBME scores, with students generally performing at a higher level in later periods, it was
decided that quarter-specific data would be used to define percentile rankings rather than using annual data.
Methods
Percentile data are obtained from annual reports from the NBME for each of the six clerkship subject exams.
For each new academic year, the last three years of complete annual data were collected, thus for academic
year 2016-2017, the data utilized are from 2012-2013, 2013-2014 and 2014-2015. Percentile data from each
quarter for these three years were collected and averaged to obtain the mean percentile score for each
quarter within each clerkship. The scores corresponding to the percentile nearest (but above) the 80th, 70th
and 5th percentile were identified and tabulated (see tables 1-6). In order to assign percentile scores for all
students, complete percentile ranging tables were generated and are shown in tables 7-12. As shown in the
tables, data from quarter 1 will be used to assign percentiles in periods 1 and 2, data from quarter 2 will be
used for period 3, data from quarter 3 will be used for periods 4 and 5 while data from quarter 4 will be used
for period 6.
For 2015-2016, the NBME changed the method for reporting scores for clinical subject exams, replacing the
normalized raw score reported previously with an equated percent correct score. This score is explained by
the NBME as follows: “[The equated percent correct score] is calculated as the percentage of items in the
total content domain that would be answered correctly based on an examinee’s proficiency level.” The new
score cannot simply be converted to the old score and thus a new set of grading tables was created for 20152016 and will continue as prescribed above for successive years unless changed by the Educational Policy
Committee.
Off cycle students
The Office of Student Affairs will ensure that percentile rankings for students who are off cycle will be
assigned according to the specific period they are completing, rather than the actual period within the annual
academic calendar. It should be noted that this system could result in students obtaining the same numerical
score on a clerkship NBME during the same period being eligible for different final grades.
Remediation
Any student who fails a clerkship NBME is expected to retake that NBME as remediation. In the past,
successful remediation has required simply achieving a score that ranks at the 5th percentile or above. This
expectation will remain the same, except that the scale used for determining this value will be the scale used
in period 6, irrespective of when the remediation exam is taken.
