What the Correction Officer test looks like
New York City Department of Correction / DCAS · Exam No. 6303 · facts last checked August 15, 2026
Eleven ability areas, which is the largest published set of any exam covered on this site. Nine of them are the ones the Police Officer notice tests; the two additions are mathematical reasoning and number facility.
This is also the one DCAS uniformed notice here that permits a calculator, and that single difference should change how you practise if you are also preparing for another title.
The mechanics the notice publishes
The multiple-choice test is conducted at a computer terminal. Multiple-choice testing for Exam 6303 was expected to begin on Thursday, 13 August 2026, following a filing period that ran 1 April to 29 May 2026.
Your score determines your position on the eligible list. As on every other exam here, passing and placing well are different achievements.
The two abilities nothing else here tests
Mathematical reasoning is defined as understanding and organizing a problem and then selecting a mathematical method or formula to solve it — reasoning through a problem to determine which operations apply. The notice illustrates it with an officer calculating the average number of miles driven for each tour.
Number facility is defined more narrowly as adding, subtracting, multiplying and dividing quickly and correctly, illustrated by compiling and verifying data such as coordinating the distribution of special meals to different facilities.
The distinction matters for practice. One tests whether you can pick the right operation; the other tests whether you can execute it accurately at speed. Preparing for them as a single topic called "maths" wastes the separation the notice draws.
The calculator rule, which is the opposite of the neighbouring exams
Basic hand-held calculators for addition, subtraction, multiplication and division are permitted on this exam. Calculators with additional features are banned and will be sealed in a Yondr pouch if brought to the site.
The Police Officer and School Safety Agent notices both state flatly that calculators are not permitted. Traffic Enforcement Agent, like this one, allows a basic four-function calculator. If you are filing for more than one of these titles, the rule follows the exam and not you.
Everything else electronic is sealed for the duration of the exam event, including headphones and earbuds. Using a prohibited device — in the testing area, a restroom, a hallway, or anywhere else — nullifies your score, bars you from civil-service tests for up to five years, and forfeits your application fee.
The other nine
Deductive reasoning, illustrated by assigning tasks and jobs and determining which can be assigned to whom. Information ordering, illustrated by reporting for roll call ready to receive work assignment orders. Written comprehension, illustrated by interpreting policies and regulations and carrying out procedures based on them.
Memorization, problem sensitivity, spatial orientation, visualization, inductive reasoning and written expression complete the set. Problem sensitivity is illustrated by observing behaviour, conduct and activities to verify compliance — which is a fair description of a great deal of the job.
What is not published
Question count, running time, section boundaries and per-ability weighting do not appear in the notice. Nor does any past form of the paper.
Where our practice papers use a length or a structure, it is one we have documented as ours. The point is to make pacing rehearsable, not to imply knowledge nobody outside DCAS has.

A free diagnostic across all 11 ability areas tells you which of the 11 areas is costing you rank, so you drill the weak one instead of the comfortable one.
Questions candidates ask
How many abilities does the Correction Officer exam test?
Eleven — the widest published set of any exam covered here. They are the nine on the Police Officer notice plus mathematical reasoning and number facility.
Can you use a calculator on the Correction Officer exam?
Yes, a basic hand-held calculator for addition, subtraction, multiplication and division. Calculators with additional features are banned and sealed in a Yondr pouch. This differs from the Police Officer and School Safety Agent notices, which prohibit calculators entirely.
What is the difference between mathematical reasoning and number facility?
Mathematical reasoning is choosing the right method or formula for a problem; number facility is performing the arithmetic quickly and correctly. The notice defines and illustrates them separately, so they are worth practising separately.
How many questions are on the Correction Officer exam?
The notice does not publish a question count, and no source outside DCAS can honestly state one.
What happens if you bring a phone to the test site?
It is sealed in a Yondr pouch until after the exam event. Using a prohibited device at any location during the event nullifies your score, bars you from civil-service tests for up to five years, and forfeits your application fee.
Is the Correction Officer test harder than the Police Officer test?
It covers more ground — eleven ability areas against nine, with arithmetic added. Whether that makes it harder depends on the candidate, and a calculator is permitted here where it is not on the Police Officer exam.
