When to take the primary certification examination: sooner or later?

Most Pathology residents take the Anatomic Pathology and/or Clinical Pathology primary pathology certification examination(s) near the end of their final year of training (i.e., Spring), whereas some postpone the examination(s) to the Fall administration of that year or even later. We compared the Spring and Fall administration pass rates of initial primary certification candidates for those who graduated in the same year they took the examination. We also compared the pass rates of same-year graduates with individuals who postponed the examination for a year or more. We also surveyed the candidates regarding the reasons they chose the Spring or Fall administration. Candidates who chose the earlier (i.e., Spring) administration were more likely to pass compared with those who took the later Fall administration (p = 0.0026 for Anatomic Pathology; p = 0.0004 for Clinical Pathology). Delaying the certifying exams beyond the calendar year of residency graduation was associated with a higher failure rate (p < 0.0001 for both Anatomic and Clinical Pathology). The survey results suggest that residents often take their certification examinations earlier to not interfere with fellowship training, because it coincides with the completion of residency training, or it is expected by their program. Pathology residents are more likely to pass the primary certification examinations when they are taken closer to the end of training, rather than postponing it to a later administration. Pathology residency program directors should encourage residents, who are deemed ready, to take their certification examinations at the earliest possible administration.
