How long does The Basic School (TBS) Phase 1 typically last?

The Basic School (TBS) Phase 1 is designed to provide new officers with essential instruction that prepares them for their future roles in the Marine Corps. The duration of approximately six months is structured to allow enough time for a comprehensive curriculum that covers a wide range of topics, including military techniques, leadership development, and tactical skills. This timeframe provides the opportunities for both theoretical learning and practical application, ensuring that graduates are well-equipped with the necessary knowledge and skills for their duties.

A shorter duration, such as three months, would not allow for sufficient depth in the training material, while nine months or one year might extend the program beyond what is necessary for foundational learning at this stage. Therefore, six months strikes a balance that enables effective teaching and learning while preparing officers to transition into subsequent phases of their training.
