Hi Lesley! Because we do not have access to the scoring algorithm for the ABPTS exams, we cannot reliably say how performance on our practice exams predicts performance on the NCS exam. The average scores on our practice exams are listed below. Approximately 96% of our participants report passing their ABPTS exam. So, if you are scoring somewhere near the range of our average scores, you are likely on track for your exam.
First attempt: 60-70%
Subsequent attempts: 75-85%
