​The CPPS Practice Exam is a 50-question online practice exam that was developed to be parallel in content and difficulty to the actual Certified Professional in Patient Safety exam. The practice exam should be regarded as a diagnostic tool to assess strengths and weaknesses, rather than a study guide for the examination. A passing score on the practice exam does not in any way guarantee a passing score on the CPPS certification examination, nor is it required to sit for the examination.
