The John H. Stamler Police Academy in Union County (NJ) utilizes the NJ Association of Chiefs of Police (NJSACOP) exam services consisting of the I/O Solutions (IOS) National Criminal Justice Officer Selection Inventory (NCJOSI) written exam series. This is a very critically scored entry-level exam that has been proven to be very challenging as a competitive instrument. Most candidates take the exam over and over without ever achieving a sufficiently adequate score to be considered in any of the selection processes for which the exam series is utilized.
