What type of evaluation must QA observe a technician accomplish every 18 months?

• A. MTL
• B. GADN
• C. LOGDET
• D. PE

Answer: (D)

Periodic hands-on competency checks are required, with QA observing the technician perform a predefined set of tasks to standard under real conditions. This kind of evaluation is called a Proficiency Evaluation. It focuses on demonstrated ability to apply procedures correctly, follow safety and quality requirements, and produce acceptable results, not just what the technician knows in theory. The 18-month interval keeps skills current, catching any decay in practical ability and ensuring procedures and equipment updates are still being applied properly.

The other items describe something different: a Master Task List is simply a catalog of tasks to perform, not a live assessment; and the other two are forms of documentation or data records, not evaluations of hands-on capability. So the Proficiency Evaluation is the correct type of evaluation QA must observe every 18 months.
