Final answer:
Commands are required to retain copies of enlisted evaluations and Chief evaluations as part of the servicemember's permanent personnel record for two years.
Step-by-step explanation:
According to military regulations, commands are required to retain copies of enlisted evaluations (evals) and Chief evaluations for a certain period. For enlisted servicemembers, the Performance Summary Record (PSR) part of the official military personnel file (OMPF) will have the evals.
The commands must keep the service records including evals, which are part of a servicemember's permanent personnel record, for two years. Chief evaluations are also maintained along with enlisted evals. It is important that these records are kept accurately and securely, as they are essential for tracking personnel performance and history.
