On a performance evaluation for a Sailor not at high year tenure (HYT) and approved for Fleet Reserve, what information should you place in Block 21?

In this scenario, the correct choice is to indicate "APPROVED" in Block 21 on the Sailor's performance evaluation. When a Sailor is not at high year tenure (HYT) and is approved for Fleet Reserve, it signifies that they have been granted permission to transition into retirement while still receiving a favorable evaluation. The term "approved" in this context indicates that their request for Fleet Reserve has been formally recognized and they are indeed set to retire honorably.

By placing "APPROVED" in Block 21, it reflects an acknowledgment of the Sailor's service and readiness to transition, which is an important aspect of their record. Maintaining accurate evaluations in this situation is crucial, as it impacts the Sailor's future benefits and ensures that their career achievements are properly documented as they move towards retirement.

Other terms like "DISAPPROVED," "PENDING," and "EXEMPT" would not accurately reflect the Sailor's approved status for the Fleet Reserve, leading to potential misinterpretations of their career and service record. Hence, "APPROVED" is the appropriate designation in this case.
