NTN Tests Practice Tests Test anxiety can affect many candidates. Ergometrics' practice tests are designed to help reduce test anxiety for candidates not familiar with video-based testing. While not necessary in order to do well, the practice tests give candidates sample item previews and rationales for correct answers. Candidates are allowed two passes through each practice test purchase. To ensure adequate preparation, it is recommended candidates use the practice tests at least one week prior to the test date. After candidates sign-up on the NTN website, they are prompted to purchase a practice test. Candidates can also log on directly to the websites below to purchase. Additionally, Ergometrics has provided practice test cards to the department to hand out to interested candidates or provide in candidate orientation packages. FireTEAM Test FrontLine Test REACT Test
