Can You Use a Calculator on the PATI Test?
The question of whether you can use a calculator on the PATI test is one of the most common concerns for aspiring police officers in Ontario. The short answer is almost always no, but certain nuances exist. This tool helps you determine the official policy based on your situation.

The OACP Certificate has replaced the old PATI test for most services.
Accommodations must be pre-approved through the official channels (e.g., OACP/TNT) under the Human Rights Code.
What is the PATI Test (Now part of the OACP Certificate)?
The Police Analytical Thinking Inventory (PATI) was a standardized exam used for many years in Ontario to assess the aptitude of police candidates. It has since been incorporated into the modern OACP Certificate process, which is a mandatory requirement for applying to most police services in the province. The core purpose remains the same: to evaluate a candidate’s cognitive abilities, including reasoning and problem-solving skills. A key section of this testing has always been Quantitative Reasoning, which is why the question ‘can you use a calculator on the pati test‘ is so prevalent.
The test is not about advanced mathematics but rather about your ability to perform fundamental arithmetic and logical reasoning under pressure—skills essential for daily police work. For more information on the application process, see our Ontario Police Application Guide.
Determining Calculator Usage: The Official OACP Policy
There isn’t a complex formula for this; the rule is straightforward. The official OACP Constable Selection System guidelines explicitly state that no electronic devices, including calculators, are permitted during the test. The reasoning is that the exam is designed to measure your innate cognitive and problem-solving abilities, which includes basic mental arithmetic.
The “Formula” for the Rule:
IF Test = OACP Certificate AND Accommodation = No THEN Calculator_Allowed = FALSE
The system is designed to test your ability without external aids. Allowing a calculator would undermine the validity of the Quantitative Reasoning section and provide an unfair advantage. This is a standard practice for many aptitude tests.
| Test Component | Description | Calculator Permitted? | Typical Rationale |
|---|---|---|---|
| Quantitative Reasoning (Word Problems, Arithmetic) | Measures ability to solve math-based problems. | No | Assesses mental arithmetic and problem-solving speed. |
| Deductive & Inductive Reasoning | Pattern recognition and logical conclusion. | No | Not a mathematical component. |
| Written Communication | Grammar, spelling, and vocabulary. | No | Not a mathematical component. |
Practical Examples
Example 1: Standard Applicant
- Input: Applicant is taking the standard OACP Certificate test.
- Input: Applicant has no pre-approved accommodations.
- Result: Calculator is NOT permitted. The applicant must rely on mental math and scrap paper provided by the test administrator.
Example 2: Applicant with Approved Accommodation
- Input: Applicant is taking the standard OACP Certificate test.
- Input: Applicant has a documented disability (e.g., dyscalculia) and has gone through the official process to request and receive an accommodation.
- Result: A calculator MAY be permitted. This is not automatic and is handled on a case-by-case basis by the OACP and its testing administrator. The permission would be granted formally before the test day.

How to Use This PATI Calculator Policy Checker
- Select the Test Version: Choose ‘OACP Certificate Test’, as this is the current standard for applicants in Ontario.
- Declare Accommodations: Indicate whether you have been formally granted an accommodation for the test. This refers to official, documented approval, not just a pending request.
- Check the Policy: Click the “Check Calculator Policy” button.
- Review the Result: The tool will provide a clear ‘Yes’, ‘No’, or ‘Maybe’ based on the official rules, along with a detailed explanation of why that policy applies.
Key Factors That Affect the “Can You Use a Calculator on the PATI Test” Rule
- OACP Official Guidelines: The primary factor is the rule set by the Ontario Association of Chiefs of Police, which currently forbids calculators.
- Test Integrity: The goal is to create a level playing field and accurately measure an individual’s unassisted cognitive skills.
- Nature of Questions: The math problems are designed to be solvable without a calculator, focusing on logic and basic arithmetic (addition, subtraction, multiplication, division, percentages, and fractions).
- Human Rights Accommodations: The only significant exception is for candidates with documented disabilities who are granted an accommodation as required by law.
- Proctoring Environment: Tests are proctored (online or in-person) to ensure rules are followed. Getting caught with an unauthorized device leads to disqualification.
- Availability of Scrap Paper: Test administrators provide blank paper, which is the only permitted tool for working out problems. If you want to know more about test scoring, see our guide on WCT test scoring explained.
Frequently Asked Questions (FAQ)
No. For all standard applicants taking the OACP Certificate test (which replaced the PATI), calculators are strictly prohibited.
The test focuses on “Quantitative Reasoning.” This includes word problems and basic arithmetic involving addition, subtraction, multiplication, division, fractions, and percentages. The questions test logic as much as pure calculation. You can find excellent practice materials in a PATI test preparation course.
You will be immediately disqualified from the test and potentially barred from re-applying for a period of time. It is considered cheating and is taken very seriously.
The test is designed to assess your ability to think on your feet and solve problems with the tools you’ll always have: your brain and basic logic. Police work often requires quick mental calculations and estimations where a calculator isn’t practical.
Yes, the test administrators will provide you with blank paper and a writing utensil to work out problems. This is the only external aid permitted for calculations.
Practice doing basic arithmetic by hand. Work through practice tests and focus on speed and accuracy. The goal is to become comfortable with mental math and problem deconstruction. Knowing how to pass the PATI test involves dedicated study without a calculator.
The WCT (Written Communication Test) and BPAD (Behavioural Personnel Assessment Device) do not have a mathematical component, so a calculator is irrelevant and not permitted.
Possibly. You must apply for an accommodation through the official OACP/TNT process well in advance of your test date. You will need to provide medical documentation. If approved, you will be notified of the specific accommodation, which may include the use of a basic calculator.
