Written Testing

​​​​The National Firefighter Selection Inventory™ (NFSI™) is a national entry-level examination tool that was engineered specifically to select qualified individuals for service as firefighters throughout the country.

A fundamental aspect of the NFSI™ is that its testing platform is an alternative to conventional firefighter written entrance examinations.

Utilizing a compensatory model, the NFSI™ assesses not only individuals’ cognitive ability, but also their behavioral predispositions.

This alternative testing model is well suited to predict success for all entry-level firefighter positions and to be in strict compliance with all federal, state and local testing guidelines and regulations.

The exam a pass/fail and hiring is not based on scores.
