Tips for preparing for a 911 operator exam include role playing situations with another person and getting a study guide for the testing precinct. College courses in public safety or 911 dispatcher training courses also prepare people for exams.
In a role playing situation, the prospective 911 operator can ask a friend to make up a 911 call scenario. The operator then provides an appropriate response and attempts to recall the call scenario after it's over. This exercise helps the operator's speaking, listening and memory.
Study guides are typically available through local police precincts. These guides have information tailored to that precinct's 911 operator exam. While 911 operator positions may not have education requirements, public safety courses and 911 dispatcher courses provide useful information that helps on 911 operator exams.
