Caseworker
Prep for NYC Caseworker (7016) and Health + Hospitals Caseworker (7018) civil service exams.
Overview
Caseworker civil service exams measure whether candidates can apply agency policy precisely to real case scenarios — reading a rule, then applying it correctly to a family or client situation, including exceptions and required timelines.
Two closely related NYC exams use a similar format: the citywide Caseworker exam and the NYC Health + Hospitals Caseworker exam. Both test substantially the same core skills, so preparation for one transfers directly to the other — but always confirm the exact requirements and passing score against the specific announcement you are applying under.
Expect scenario-based situational judgment questions covering confidentiality, mandated reporting, home-visit timelines, and documentation — the actual day-to-day decisions caseworkers make.
Basic math shows up in caseload, scheduling, and percentage-based word problems rather than advanced arithmetic, and logical reasoning sections test whether you can draw valid conclusions from stated policy rules.
The merit system
This is a competitive civil service title: your written exam score determines your rank on the eligible list, and appointments are typically made in score order as vacancies open.
Hiring is usually multi-stage — the written exam sets your rank, and candidates reached from the list continue through background investigation, reference checks, and other required steps.
Eligible lists are generally active for a limited window. Respond promptly to any canvass notice so a strong score is not wasted by a missed deadline.
Veterans and residency credits may apply to a passing score depending on the jurisdiction and announcement. Confirm exactly how credits are calculated for this title rather than assuming a blanket rule.
What these exams typically test
Civil service written tests usually measure more than raw subject recall—they test how you apply rules, prioritize, and work under time pressure.
- Reading comprehension of case policy, confidentiality rules, and procedural passages.
- Applying a stated rule correctly to a specific case scenario, including exceptions.
- Situational judgment: safety concerns, mandated reporting, and client interactions.
- Confidentiality and information-sharing rules across agencies and with clients.
- Basic arithmetic for caseload counts, scheduling, and percentage-based word problems.
- Logical reasoning: valid conclusions from stated conditional rules.
- Documentation and case-file requirements, including timelines for logging contact.
- Following multi-step written procedures without skipping or reordering steps.
Topic checklist
- Home-visit timelines and safety-concern escalation
- Confidentiality and cross-agency information sharing
- Mandated reporting requirements and timelines
- Case documentation and file requirements
- Client and family interaction scenarios
- Reading comprehension of case policy language
- Basic math: caseload counts, scheduling, and percentages
- Logical reasoning with conditional ("if/then") rules
- Exam-specific weights and sections — cross-check your official announcement
How to prepare
- Practice reading short policy passages and immediately applying them to a new scenario — this "read the rule, then apply it" pattern is the core skill the exam tests.
- Work through situational judgment items and explain, for each one, which specific line of the stated policy justifies the correct answer rather than what "seems reasonable" or most compassionate.
- Drill basic arithmetic word problems involving caseloads, percentages, and averages until the calculations feel automatic rather than effortful.
- Practice logical reasoning with simple conditional statements ("if X, then Y") and negations ("not Y, so not X") — a small number of question patterns repeat throughout this section.
- Review confidentiality and mandated-reporting rules closely, since a meaningful share of both reading and situational judgment questions are built around these exact procedures.
- Take at least one full-length timed practice session before test day so pacing feels familiar rather than rushed.
Common mistakes to avoid
- Answering from instinct or empathy instead of the specific procedure described in the passage. The exam supplies the governing rule — apply it exactly, including any stated exceptions.
- Assuming a supervisor's informal approval overrides a written confidentiality or reporting requirement — it generally does not on this exam.
- Rushing reading-comprehension passages and missing a qualifying word ("unless," "except," "must") that changes which answer is correct.
- Treating logical reasoning items as intuition checks rather than working through the stated conditions methodically.
- Skipping practice on basic math because it feels easy — careless arithmetic errors under time pressure are a common, avoidable point loss.
Exam day strategy
- Read the full policy passage before looking at the answer choices, and note any qualifying words ("unless," "must," "may not") before deciding.
- For situational judgment items, ask "what does the stated policy require here" rather than "what would I personally do."
- On logical reasoning items, write out the stated rule in your own words before evaluating each answer choice against it.
- Keep a steady pace — flag anything taking longer than about 90 seconds and return to it if time allows.
- Double-check math word problems by re-reading the question after calculating, since misreading what is actually being asked is a common source of avoidable errors.
