What is on the Environmental Police Officer exam
New York City Department of Environmental Protection / DCAS · Exam No. 6305 · facts last checked August 9, 2026
Exam 6305 is a multiple-choice test given at a computer terminal. Your score determines your place on an eligible list, and you must achieve at least 70% to pass. The notice publishes no question count and no time limit, so any figure you are given for either did not come from DCAS.
What it does publish is nine ability areas with a definition and a worked example each. Those nine are identical — element for element — to the nine on the NYPD Police Officer notice and the nine on the School Safety Agent notice. Nothing about the constructs is unique to this title; what is unique is the job the examples are drawn from.
The nine abilities and the notice's own examples
Deductive reasoning — applying general rules to specific problems and deciding whether an answer makes sense. The example is deciding whether an individual accused of trespassing should be arrested. Inductive reasoning — combining separate pieces of information to form general rules or conclusions, illustrated by interpreting the intentions of departmental guidelines and how they relate to an incident.
Information ordering — following a given rule or set of actions in a certain order, illustrated by deciding the next appropriate action when confronting a disorderly individual. Problem sensitivity — telling when something is wrong or likely to go wrong, illustrated by choosing an appropriate action for someone in need of medical assistance.
Memorization — remembering words, numbers, pictures and procedures, illustrated by recalling the details of a suspect or vehicle fleeing the scene of a crime. Spatial orientation — determining where you are in relation to an object or where an object is in relation to you, illustrated by interpreting a road map to decide the most efficient route to a crime scene.
Visualization — imagining how something looks when moved or rearranged, illustrated by comparing the facial characteristics of a suspect to a photograph on file. Written comprehension — understanding written sentences and paragraphs, illustrated by reviewing an incident report. Written expression — writing so that others will understand, illustrated by recording the details of an unusual incident.
What the shared ability list does and does not mean
It means the constructs are well-defined and heavily examined across DCAS titles, so nothing on this paper is experimental. It also means preparation transfers between these three exams at the level of the skill: a candidate who can hold a fleeing-vehicle description in their head can do it whether the vehicle is on a city street or a fire road.
It does not mean the papers are interchangeable. The examples show why. Spatial orientation for a Police Officer is a street grid; here the notice's own example is a road map and an efficient route to a scene, and the job description puts assignments across ten counties. A candidate practising only city-block problems is practising the right construct in the wrong geometry.
The same holds for memorization. A watershed patrol log has plates, gates, access roads and times in it; a lobby log has visitors and passes. The recall load is the same shape and the vocabulary is not.
Test-day conditions
Calculators are not permitted. Neither are phones, smart watches, cameras, e-cigarettes, vape pens, headphones, earbuds or other portable media and electronic devices — anything brought to the site is sealed in a Yondr pouch until after the exam event. Using a prohibited device, or taking one out of the pouch without authorisation anywhere in the building including a restroom or hallway, nullifies your score, forfeits your application fee and can bar you from civil service tests for up to five years.
A medical assistive device that alerts or vibrates needs written authorisation from DCAS in advance. You cannot bring anyone with you while being processed or tested, and nobody may wait for you inside the centre. Your admission notice appears on your OASys dashboard fourteen days before testing is expected to begin.
The notice also flags that certain questions may need to be answered on the basis of documents or other information supplied to candidates on the day. Nothing needs memorising in advance for those, but the clock does not stop while you find your way around an unfamiliar document.
Scoring, the list, and why rank matters more here
Seventy per cent passes; the score above it decides your list number. The eligible list determines the order in which candidates are considered and is usually active for four years, and selection runs under New York Civil Service Law § 61 — the appointing authority may choose among the three highest-ranked candidates willing to accept appointment.
The reason rank carries more weight on this title than on most is the examination frequency. DCAS runs Police Officer twelve times a year; it runs Environmental Police Officer twice. A candidate who passes but is not reached does not simply try again next month. The next filing periods on the annual schedule open 2 December 2026 and 7 April 2027.
An appeal against the rating goes to the DCAS Committee on Manifest Errors through the online application system and must state its reasons; the notice adds that an appeal may result in a different rating, which is not a promise that the difference runs upwards.

A free diagnostic across all 9 ability areas tells you which of the 9 areas is costing you rank, so you drill the weak one instead of the comfortable one.
Questions candidates ask
How many questions are on the Environmental Police Officer exam?
Notice 6305 does not publish a question count or a time limit. It publishes the nine ability areas, the 70% pass mark, and that the test is taken at a computer terminal.
What abilities does the exam test?
Nine: deductive reasoning, inductive reasoning, information ordering, memorization, problem sensitivity, spatial orientation, visualization, written comprehension and written expression.
Is it the same test as the NYPD Police Officer exam?
No, but the ability list is identical. The constructs are the same nine; the job context the questions are written around is not, and the notice's own examples differ accordingly.
Can I use a calculator?
No. The notice states that calculators are not permitted, and no other electronic device is allowed either.
What score do I need?
At least 70% to pass. Above that, the score sets your rank on the eligible list, which determines when you are considered for appointment.
Is there a memory section?
Memorization is one of the nine named abilities, illustrated in the notice by recalling the details of a suspect or vehicle fleeing the scene of a crime.
