The National Criminal Justice Officer Selection Inventory (NCJOSI) is a set of cognitive aptitude exams used by EMPCO as pre-employment tests for police officers, road patrol, and deputy sheriff's positions.
The test includes 120 questions, with a time limit of 2.5 hours and a pass threshold of 70%.
NCJOSI's question focus on two main domains:
- Cognitive Ability: Deductive reasoning, flexibility or closure, inductive reasoning, information gathering, problem sensitivity, selective attention, spatial orientation, verbal comprehension, verbal expression, and visualization.
- Psychological measures: Antisocial behavior, positive outlook, orderliness/diligence, and socialization.
Please note that there are two different versions of the test- NCJOCI 1 & NCJOSI 2. You may not know which version you will be taking! The main difference between them is that NCJOSI 1 is more prolonged and includes more categories, and NCJOSI 2 is shorter with fewer categories but with a stricter duration.
If you're applying for a law enforcement job in Michigan, you'll need to take the MCOLES test and a physical abilities test in addition to the NCJOSI.
