Suffolk County Civil Service lists 61 examinations as of September 30, 2026 — covering open competitive exams (available to any qualified candidate), promotional exams (for current Suffolk County employees advancing within the system), and continuous recruitment positions (no fixed deadline, apply at any time). The three sections below organize all 61 exams by type with deadlines and test dates clearly flagged.

All exams carry a $40 non-refundable filing fee except law enforcement promotional and competitive titles (Captain, Lieutenant, Police Officer, Principal Detective Investigator), which carry a $125 fee. Contact the Suffolk County Department of Civil Service for application materials, qualification details, and fee waiver information.

Open competitive exams are available to any candidate who meets the minimum qualifications — you do not need to be a current Suffolk County employee. Titles marked OC + PROM have both an open competitive and a promotional exam running simultaneously.

Promotional exams are open exclusively to current Suffolk County employees who hold a qualifying title in permanent competitive status. Appointments from promotional lists are made before open competitive lists. Titles that also appear in Section 1 (OC + Prom) are listed there — this section shows exams where no open competitive version exists.

Continuous recruitment positions have no application deadline and no scheduled exam date. Applications are accepted on a rolling basis and reviewed as positions become available. These are typically professional, clinical, or specialized titles that require specific credentials. Apply as soon as you are ready — there is no advantage to waiting.
