This pass score was established using a Mastery Angoff standard\u2010setting exercise with a group of EM experts. Learners participated in baseline testing on a simulated model and performance was assessed by two raters. Learners then watched an instructional video and participated in an individualized teaching session. Learners underwent deliberate practice followed by posttesting until mastery was achieved. Score differences in baseline testing and posttesting were analyzed using a paired t\u2010test. Pre\u2010 and posttesting surveys were also completed by participants.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Twenty\u2010eight PGY\u20101 to \u20104 residents volunteered to participate in the study.

The mean (\u00b1SD) number of items correct on the checklist for initial testing was 8.5 of 19 (\u00b12.7), while the mean (\u00b1SD) final score was 18 of 19 (\u00b10.6; p\u00a0&lt;\u00a00.001).
