Final answer:
To receive a Progressing (3.4) evaluation, a sailor must have at least a Promotable (P) recommendation on their previous evaluation.
Step-by-step explanation:
A sailor may not receive a Progressing (3.4) evaluation without receiving at least a Promotable (P) promotion recommendation on their previous evaluation.
The evaluations and promotions within the Navy follow specific guidelines, and to be eligible for a Progressive rating, the sailor needs to have demonstrated a level of performance and potential deemed suitable for the next higher rank, as indicated by their previous evaluations.
