OACP SSPO Test Guide: Format, Timing and Scoring
August 14, 2026
The OACP Certificate Part B cognitive assessment is the SIGMA Survey for Police Officers (SSPO). It is designed to measure how well a candidate can make sound decisions, work with written and numerical information, and recognize clear, accurate professional language.
Knowing the structure is useful, but the real preparation advantage comes from turning that structure into a practical pacing and decision-making plan. This guide explains what to expect and how to practise without treating one score as a prediction of your official result.
OACP SSPO format at a glance
The official OACP study guide describes a timed assessment with 74 multiple-choice questions in 35 minutes. The questions are divided into two sections:
- Incident Report Writing Aptitude: 44 questions. These questions cover spelling, vocabulary, grammar and punctuation.
- Police Problem Solving: 30 questions. These questions use written scenarios and may include policies, maps, floor plans or numerical information.
That works out to an average of slightly less than 30 seconds per question. It is only an average: a spelling decision may take a few seconds, while a scenario with several facts may require more time. The goal is not to force every question into the same time limit. It is to avoid spending several minutes on one difficult item while easier questions remain unanswered.
Build pacing checkpoints before test day
A useful pacing plan has only a few checkpoints. Checking the clock after every question can interrupt concentration, but waiting until the final minute creates a different problem. During practice, try checkpoints such as:
- 10 minutes elapsed: approximately 21 questions completed
- 20 minutes elapsed: approximately 42 questions completed
- 30 minutes elapsed: approximately 63 questions completed
- Final 5 minutes: complete the remaining questions and revisit selected items if time permits
These are planning targets, not rigid rules. Your position may vary because the questions do not all require the same amount of work. If you are behind at a checkpoint, the response should be controlled: make quicker decisions on clear items and stop repeatedly rereading questions that you have already understood.
Scoring changes the guessing decision
Try not to guess, because incorrect answers are penalized on the official assessment, but the penalty formula is not known.
The official guide also states that unanswered questions are not penalized. Because the size of the incorrect-answer penalty is not published, there is no responsible way to calculate a universal guessing threshold. Instead, use an evidence-based decision ladder:
- Answer when the solution is clear. Select it and continue without unnecessary rechecking.
- Eliminate choices when you have a reason. Compare each remaining option with the facts or language rule in the question.
- Flag an item when more work may help. Return after collecting the answers you can reach efficiently.
- Leave it unanswered when you have no defensible basis for choosing. Random selection is not the same as reasoned elimination.
Police Ready practice assessments currently report correct-answer scores. They do not reproduce an undisclosed official penalty formula, so use your results to identify patterns in accuracy, timing and subject knowledge.
A three-stage practice method
1. Learn the skill without a timer
Start with focused work on spelling, vocabulary, grammar, mental arithmetic, maps and rule application. At this stage, accuracy and explanation matter more than speed. If you miss a question, write down why: missing knowledge, misreading, calculation error or time pressure.
2. Add short timed sets
Complete groups of 10 to 20 questions under a realistic pace. Short sets make it easier to test one adjustment at a time. For example, you might practise reading the question before a long scenario, or checking a map’s orientation before tracing a route.
3. Complete full 35-minute rehearsals
Use a full-length assessment only after you have reviewed the underlying skills. Recreate the conditions you control: silence notifications, clear your desk, avoid a calculator and do not pause to look up rules. Afterward, review every uncertain question, including correct answers reached for the wrong reason.
What to review after every attempt
A useful review log is more valuable than a list of scores. For each missed or uncertain item, record:
- the skill or question type;
- the fact, rule or calculation you missed;
- whether time pressure affected the decision;
- the method that leads to the supported answer; and
- one action to take before the next assessment.
Look for recurring causes. Several spelling errors need a different study response than several scenario errors caused by adding facts that were never provided.
Test-day preparation
- Review the technical and proctoring instructions in your personal OACP materials.
- Confirm your computer, browser, webcam, identification and testing space requirements early.
- Sleep normally and avoid making major changes to caffeine, food or routine.
- Begin with the pacing checkpoints you already used in practice.
- Read for accuracy, make deliberate decisions and keep moving.
