Exam Passing Score

A panel of subject-matter experts established a passing score for the Nonsterile Compounding Exam using industry best practices. The method used by the panel, as directed by a psychometrician, is the modified-Angoff method. This method requires experts (panel members) to evaluate individual test questions and estimate the percentage of qualified pharmacy technicians that would be able to answer each question correctly. These estimates were analyzed for consistency and averaged to produce the passing score. The passing score and candidate results are reported as scaled scores. The passing scaled score for the Nonsterile Compounding Exam is 300. The range of possible scores is 0 to 400.
