What Are Public Safety Tests?

Public safety tests are pre-employment assessments used to evaluate whether applicants have the skills needed for emergency and public service roles.

These tests may measure:

• reading comprehension;
• written communication;
• report writing;
• grammar and spelling;
• basic math;
• situational judgment;
• decision-making;
• typing speed and accuracy;
• data entry;
• multitasking;
• listening;
• memory and observation;
• map reading;
• mechanical aptitude;
• logical reasoning;
• following written instructions;
• emotional control;
• professional judgment.

The exact test depends on the job.

A police officer exam is not the same as a dispatcher test practice test. A firefighter written exam is not the same as CritiCall. A correction officer exam may include custody and facility safety scenarios that do not appear on a general police test.
