Hi Rachel,
A score of 500/800 (62.5%) is passing for the NCS exam. However, some questions are thrown out upon review after the exam. You can find more details on this website, and below is the excerpt about scoring: https://specialization.apta.org/about-specialist-certification/exam-development
“Examination Scoring
After key validation, a procedure designed to identify items that may be miskeyed or not functioning as expected, candidates’ responses are scored and converted to standard scores. The standard scores are scaled so that the minimum passing score on each examination is 500.
The certification examinations assess a clearly defined domain of knowledge and skills. Candidates are certified upon achievement of a passing score on the examination.”
