Final answer:
A performance trait grade indicating deficiencies means that a sailor needs to correct certain aspects of their conduct or skills before being considered for promotion.
Step-by-step explanation:
The performance trait grade you’re asking about refers to a specific evaluation in the U.S. Navy's Enlisted Performance Evaluation system. When a sailor receives a performance trait grade that indicates deficiencies must be remedied before promotion, it signifies that there are areas in which the sailor needs improvement. This could be in various aspects, such as leadership, technical skills, or adherence to regulations. The performance trait grade essentially states that until the sailor addresses these deficiencies, they are not recommended for promotion. This reinforces the notion that in the military, individuals must demonstrate proficiency in all their duties and responsibilities in order to advance in rank.
