Which entity is notified by HR after a military service member's return?

The correct choice is the Division of Standards and Training. When a military service member returns from active duty, it is important for the law enforcement agency to ensure that their training and qualifications are up to date. The Division of Standards and Training is responsible for overseeing these training requirements for state police personnel, which includes verifying that returning members are re-acclimated and have completed any necessary refresher courses or updates to their skills.

This notification process is part of maintaining compliance with both internal policies and legal obligations regarding re-employment of military personnel in law enforcement roles. The Division of Standards and Training plays a crucial role in ensuring that all members of the force uphold the highest standards of training and effectiveness upon their return.
