Exam Pass Rates

The following statistics reflect the percentage of test-takers who passed the wound, ostomy, continence and foot care exams in 2015. These numbers reflect pass rates of all exams taken, that is, the number of passing scores divided by the number of tests administered. Candidates taking the test on their second attempt (i.e., repeat candidates) tend to pass at rates around 50%. As of today, more than 7,600 Wound, Ostomy, Continence and Foot Care nurses are currently certified by the WOCNCB.
