How often are proficiency and conduct marks recorded?

Proficiency and conduct marks are recorded semi-annually in the Marine Corps. This means that they are assessed and documented twice a year, typically at the end of each six-month period. This standard allows for an evaluation of a Marine’s performance and behavior over a significant time frame, which is crucial for making informed decisions regarding promotions, assignments, and other key career milestones. By using a semi-annual system, it provides a balance where supervisors can adequately observe and assess a Marine’s progress while also ensuring that the evaluations remain relevant and timely.
