3. In effort to continually align with best practices, The 2022 21st ISTM Certificate of Knowledge Exam will be composed of 220 questions instead of the traditional 200 questions. The additional 20 items will be unscored and will not impact your exam score. These unscored items are embedded throughout the exam to assess their statistical characteristics and viability as future scored items.

4. Scoring: Please note that you will NOT receive a score immediately after taking the exam. Pass/Fail information will be emailed after the psychometricians have reviewed all of the completed exams. Please be patient as grading may take 8 to 10 weeks. In the interim, neither this system nor the ISTM Secretariat will have pass/fail information.
