This document provides a step-by-step guide to understanding and managing one's career under the Navy's Perform to Serve (PTS) system. PTS uses performance criteria to determine which Sailors are retained in order to maintain experience levels. It affects Sailors E-3 to E-6 with 14 or fewer years of service. The top performers in each year group and rating are retained. Sailors are ranked based on factors like pay grade, evaluation scores, time in service, and exam scores. The guide defines important terms and advises Sailors to meet with career counselors to understand their options, like retraining, under the PTS system.
