When must a Certification Skill Check (CSC) be conducted?

• A. All of the above
• B. After majority recommendation with min time met
• C. Upon completion of OJT time or additional OJT time
• D. Upon reaching 100% target time

Answer: (A)

The CSC should be conducted whenever the trainee reaches any of the defined points that warrant formal skill verification. In practice, that means performing a Certification Skill Check after the trainee has met the minimum required practice time and there is a majority recommendation to proceed; when OJT time is completed (or additional OJT time is completed); and when the trainee reaches 100% of the target training time. These triggers exist to ensure the trainee has had enough hands-on practice and time to demonstrate competency, so safety-critical tasks are verified before moving forward. In short, a CSC is scheduled at all the points where enough progress and practice have occurred to meaningfully assess readiness, which is why all the listed scenarios together represent the correct approach.
