What is the timeframe to perform a BCA before a PRT?

The timeframe to perform a Body Composition Assessment (BCA) before a Physical Readiness Test (PRT) is established to ensure that it accurately reflects a sailor's fitness level in the lead-up to the test. Conducting the BCA 45 days prior to the PRT allows time for any necessary interventions, adjustments, or improvements to be made in a sailor's physical fitness and body composition if needed. This allows both individuals and their command to ensure that they are prepared for the PRT, aligning with the goals of the Navy’s fitness programs.

This time frame is specifically designed to provide an adequate period for measurement and potential remediation, which is essential for maintaining health standards and performance within the Navy.
