Ontario Police Constable Certificate Prep — Sigma Survey (SSPO)
Last updated: September 2026
The OACP Certificate is a required step for applying to police services across Ontario. The core testable component is the Sigma Survey for Police Officers (SSPO) — a strictly timed exam covering language/report-writing skills and police problem-solving judgment. Use these free practice questions to prepare for the current test format.
OACP Certificate Process Overview
The full OACP Certificate process includes a file submission stage, the Sigma Survey for Police Officers (SSPO) knowledge assessment, and the PRF-R — a 307-item personality inventory that is not pass/fail and has no right or wrong answers. This page focuses on the SSPO, since it's the component candidates can directly prepare for through practice.
SSPO Exam Structure
The Sigma Survey for Police Officers (SSPO) is designed to evaluate core verbal communication, written documentation accuracy, and practical problem-solving capabilities required for effective police constable duties across Ontario police services.
- 74 total questions in 35 minutes — under 30 seconds per question on average, making pacing critical
- Section A (Language/Report Writing) — approximately 44 questions testing spelling, vocabulary, punctuation, and grammar skills relevant to writing accurate police incident reports
- Section B (Police Problem-Solving) — approximately 30 questions testing situational judgment and the ability to assess police-relevant scenarios and choose the most appropriate response
- The test does not require prior policing knowledge — it evaluates core language and reasoning skills applicable to police report writing and decision-making
- If unsure of an answer, leaving it blank may be preferable to guessing incorrectly, depending on current OACP scoring guidance — confirm exact guidance with official OACP materials before test day
Because candidates must complete both sections within the single 35-minute testing window, effective time management and familiarity with rapid-fire questions are vital for a passing result.
OACP Sigma Survey (SSPO) Core Domains
Section A: Spelling & Vocabulary Accuracy
Identifying correct spellings of commonly misspelled English words and words frequently used in law enforcement, incident narratives, and legal documentation.
Section A: Grammar, Punctuation & Report Writing
Detecting grammatical errors, syntax flaws, dangling modifiers, subject-verb agreement issues, and comma splices in incident report statements.
Section B: Police Problem-Solving & Judgment
Evaluating practical community scenarios and choosing the most logical, fair, and professional immediate action under standard operating procedures.
Section B: Task Prioritization & Situational Reasoning
Ordering emergency and non-emergency tasks, identifying relevant facts, and maintaining public safety in ambiguous or evolving community situations.
Why Speed Matters as Much as Accuracy
With 74 questions in just 35 minutes — averaging under 30 seconds per question — candidates who haven't practiced under real time pressure often run out of time before reaching later questions. Timed practice is essential to condition your pacing so you don't stall on difficult items and can complete both Section A and Section B within the strict time allotment.

A minor two-vehicle collision in a private shopping plaza parking lot where both drivers report zero injuries and vehicles are safely parked. 3.

How to Prepare for the OACP Exam
Timed Practice Under Strict Conditions
With 74 questions in 35 minutes, you have roughly 28 seconds per question. Simulating real exam time pressure during prep prevents running out of time on later sections.
Master Grammar, Spelling, and Punctuation Fundamentals
Section A comprises approximately 44 questions (over half the test). Brushing up on homophones, spelling of incident terms, subject-verb agreement, and comma rules delivers fast score gains.
Internalize the "Most Appropriate Response" Policing Mindset
Section B situational judgment questions require prioritizing public safety, impartial fact-finding, de-escalation, and policy adherence over personal opinions or rushed actions.
Review Official OACP Resources & Guidelines
Assessment guidelines and testing administration procedures can receive periodic updates. Always consult the official OACP Certificate candidate guide for current testing platform instructions.
Treat the Certification Process Holistically
Remember that the SSPO is accompanied by the PRF-R personality assessment and file submission. Ensure your driving abstract, documentation, and physical fitness preparation are progressing alongside your exam prep.
