Which New York jurisdictions use this examination
The Department writes one test and local civil service commissions administer it, mostly on a common date in June. Not every New York jurisdiction uses it, and the differences between those that do are worth knowing.
One test, many commissions
The Department states that over ninety local Civil Service Commissions and Personnel Officers administer the merit system in New York, and that most local civil service examinations outside New York City are prepared by the Department.
Oneida County and the City of Watertown announced Police Sergeant examinations under different exam numbers and held them on the same day, which is what a state-scheduled common date looks like from the outside.
What differs between them
Each commission publishes its own announcement, and they disagree. Across four read in full: the fee ranges from waived to $125; the minimum qualification is three years in one and five in another; the seniority table is different in each; the eligible list is fixed at two years in one and one to four in others; and one adds a Part II on its own departmental manual while three do not.
That is why your own announcement is the document that governs, and why nothing here states a fee, a salary or a filing date as though it were the same everywhere.
Where this examination is not used
New York City runs its own promotional examinations through DCAS, scored on the NYPD Patrol Guide. Nassau County has self-prepared its Police Sergeant examination, and its 2017 announcement named a copyrighted textbook.
If your announcement points you at the state's Police Supervisors/Investigators test guide, this is your examination. If it names a book, it is not.
