For information on commissioning programs, which OPNAV instruction should be referred to?

The correct answer is OPNAV 1420.1, which specifically outlines the Navy's commissioning programs. This instruction provides comprehensive guidance on the various paths available for enlisted personnel to become commissioned officers in the Navy, including relevant eligibility criteria, application procedures, and program details. It serves as a critical resource for service members seeking to understand their opportunities for commissioning and the necessary steps to pursue their career advancement through these programs.

In contrast, the other options cover different subjects related to personnel and training but do not specifically address the commissioning processes. OPNAV 1400.1 deals with officer appointments and promotions, OPNAV 1430.1 is focused on advancements for enlisted personnel, and OPNAV 1450.1 pertains to the vocational and technical training programs. Thus, while all are important for Navy personnel, OPNAV 1420.1 is the dedicated instruction for commissioning programs.
