The CritiCall is unique among recruitment tests - it evaluates your cognitive skills and doesn't require prior 9‑1‑1 knowledge, yet it's still described by candidates as challenging and arduous.
The test is developed by Biddle Consulting Group, an American company. In Canada, it's used by the Ontario Provincial Police (OPP) for dispatchers in the province, as well as by the RCMP nationwide.
If you're scheduled to take the Ontario Provincial Police CritiCall exam or the RCMP CritiCall, this page will get you familiarised with the ins and outs of the assessment.
