Which document must be maintained to document completion of training and operator proficiency?

The NVD Training Certificate or Memorandum for Record (MFR) is the essential document that demonstrates an individual's successful completion of training and their proficiency in operating certain equipment or vehicles. This certificate serves as official proof that the training requirement has been met, which is crucial for ensuring that operators are both competent and compliant with safety regulations and operational standards.

Having a formal document like the NVD Training Certificate helps maintain accountability in the training process, enabling supervisors and command to verify that personnel have undergone the necessary instruction and can perform their duties safely and effectively. In contrast, other options such as an Accident Report Summary, Driver's Log Book, or Training Attendance Record, while relevant to operational contexts, do not specifically serve as formal certification of training completion and operator proficiency. These documents may play roles in tracking activities or incidents but lack the direct linkage to confirming that training has been successfully completed and that operators meet proficiency standards.
