How many years must the naval aircraft NDI tech school and FRC retain records of training materials, tests given, and individual test scores?

The correct answer is that records of training materials, tests given, and individual test scores must be retained for 3 years. This duration ensures that there is adequate documentation for training effectiveness and accountability. It allows for sufficient time to assess the learning outcomes and any necessary follow-up training. Retaining records for this length of time complies with various regulatory requirements and ensures that the data is available for audits or performance evaluations that may occur over that period. Keeping training records for 3 years strikes a balance between maintaining necessary documentation and managing resources effectively.
