Sample question 1 of 3
Written Comprehension
Visits are booked in advance through the visit office. A booked visit is held for fifteen minutes past its start time; after that the slot may be released to a waiting visitor. Visitors who arrive late but within the fifteen minutes keep the remainder of their original slot, not a full session. The visit office may extend a session where a delay was caused by the facility itself.

What you have to take
Three New York exams, and this is the city correction one
New York City runs its own Correction Officer examination through DCAS. It is not the city POLICE examination, which measures nine abilities rather than eleven, and it is not the New York STATE Entry-Level Police Officer Series used by county agencies. It is also not the New York State Correction Officer Trainee process, which has no written test at all. Getting that right is the first thing to settle, because the four are prepared differently.

How this preparation is built
These are the automated checks every question goes through before it can be served. They are run over the whole bank, by software, every time it changes.
- Every question is original
- Every question carries an approval record
- Every answer is explained
- The bank is measured, not just proofread
How questions are checked
- Every question is original
- Each one is written for RankHigh. Nothing is taken from a real examination, a competitor's bank or a public question set, and every new batch is checked for duplicates against every other question in the catalog.
- Every question carries an approval record
- A question that has not been through these checks is not served at all. That is what this product serves, not what has been written.
- Every answer is explained
- All of them, not the hard ones. An explanation says why the keyed answer is right and what each of the other options gets wrong, so a question you got wrong is worth more to you than one you got right.
- The bank is measured, not just proofread
- Answer positions, answer lengths and repeated scenarios are measured across the whole bank against chance. Where a pattern would let somebody pick the answer from its shape instead of its content, the questions are repaired — because a pattern you can learn here is one that will not be there on the day.

Questions
Is this the same as the New York State correction officer exam?
No, and this is the one worth checking before you buy anything from anybody. New York STATE scores its Correction Officer Trainee examination from an online questionnaire about your education, certification, licensure and experience — the Department of Civil Service says the questionnaire is the test. There is no written examination to prepare for. This product is the New York CITY examination, run by DCAS, which is a computer-based multiple-choice test of eleven cognitive abilities.
Is this the same as the NYPD police exam?
No. DCAS runs both, and it defines their abilities in the same words, which is why they look similar from outside. The police examination measures nine abilities; this one measures eleven — the same nine plus number facility and mathematical reasoning. They are separate examinations with separate eligible lists, and RankHigh keeps them as separate preparation products.
What is the difference between number facility and mathematical reasoning?
Number facility is whether you can do the arithmetic accurately and quickly when the calculation is already set out. Mathematical reasoning is whether you can work out which calculation the situation calls for in the first place — the arithmetic in those questions is deliberately light. DCAS scores them separately, and they need opposite remedies: one is drilled, the other is a comprehension problem wearing an arithmetic costume. RankHigh trains and reports them separately for that reason.
How is the memory section tested?
The Notice of Examination defines memorization as remembering information such as words, numbers, pictures and procedures, and says certain questions may need to be answered on the basis of documents or other information supplied on the day of the test. RankHigh's memory items work that way: the material is shown, the time runs out, and it cannot be reopened. DCAS publishes no study period at all, so the time allowed here is RankHigh's training design and is not presented as the examination's.
What score do I need?
The Notice of Examination states 70% to pass. Beyond that, appointment runs down a ranked eligible list, so the practical question is not whether you passed but where you rank — and that depends on who else took the examination.
Is this a subscription?
No. It is a single payment of $49. Nothing recurring, nothing to cancel, and no card kept on file for later.
More questions (2)
How long do I have access?
Your access opens online as soon as payment clears — there is nothing to wait for in the post. Your one-time purchase includes 90 days of access from the time payment clears. No subscription. No automatic renewal. One payment, nothing recurring, nothing to cancel.
Does RankHigh guarantee a passing score?
No, and be careful with anyone who does. What this does is show you which areas are costing you points and give you focused practice on them. The work is still yours to do.
