OACP Practice Test: Ontario Police Certificate Questions, Answers and Prep Guide

The OACP practice test helps Ontario police applicants prepare for the skills assessed during the Ontario Association of Chiefs of Police certificate process.

The OACP Certificate is used as an entry-level testing and screening step for police officer and special constable applicants in Ontario. The OACP says its redesigned Constable Selection System helps police services across Ontario select suitable applicants, and that the certificate is valid for one year from the date issued. :contentReference[oaicite:0]{index=0}

Depending on the current process, OACP-style preparation may involve:

• reading comprehension;
• written communication;
• grammar and spelling;
• vocabulary;
• problem solving;
• reasoning;
• memory and observation;
• map reading;
• math;
• situational judgment;
• attention to detail;
• police-style decision-making.

Recommended prep:

These are original OACP-style practice questions for study purposes. They are not official questions from OACP, Ontario police services, TNT Justice Consultants, PoliceCert, any police service or any test provider.

What Is the OACP Certificate?

The OACP Certificate is part of the Ontario police applicant process.

The Ontario Association of Chiefs of Police says it created the OACP Certificate Testing site to deliver entry-level testing for police officers and special constables in Ontario. The OACP Certificate Testing site also says the redesigned OACP Constable Selection System is intended to assist police services in selecting suitable applicants. :contentReference[oaicite:1]{index=1}

In practical terms, many Ontario police applicants need to obtain an OACP Certificate before applying to police services that require it.

You should always verify current instructions through:

• the official OACP Certificate site;
• the OACP careers in policing page;
• the police service you are applying to;
• your application email package;
• official certificate testing instructions.
