Abstract

Background and objectives Medical specialty and subspecialty fellowship programs administer subject-specificin-training examinations to provide feedback about level of medical knowledge to fellows preparing for subsequent board certification. This study evaluated the association between the American Society of Nephrology In-Training Examination and the American Board of Internal Medicine Nephrology Certification Examination in terms of scores and passing status. Design, setting, participants, & measurements The study included 1684 nephrology fellows who completed the American Society of Nephrology In-Training Examination in their second year of fellowship training between 2009 and 2014. Regression analysis examined the association between In-Training Examination and first-time Nephrology Certification Examination scores as well as passing status relative to other standardized assessments. Results This cohort included primarily men (62%) and international medical school graduates (62%), and fellows had an average age of 32 years old at the time of first completing the Nephrology Certification Examination. An overwhelming majority (89%) passed the Nephrology Certification on their first attempt. In-Training Examination scores showed the strongest association with first-time Nephrology Certification Examination scores, accounting for approximately 50% of the total explained variance in the model. Each SD increase in In-Training Examination scores was associated with a difference of 30 U (95% confidence interval, 27 to 33) in certification performance. In-Training Examination scores also were significantly associated with passing status on the Nephrology Certification Examination on the first attempt (odds ratio, 3.46 per SD difference in the In-Training Examination; 95% confidence interval, 2.68 to 4.54). An In-Training Examination threshold of 375, approximately 1 SD below the mean, yielded a positive predictive value of 0.92 and a negative predictive value of 0.50. Conclusions American Society of Nephrology In-Training Examination performance is significantly associated with American Board of Internal Medicine Nephrology Certification Examination score and passing status.
