Core investigator skills
Practice evidence and confidentiality rules, chronology, report writing, source or witness interviews, caseload math, and conditional reasoning. The goal is to support a conclusion with documented facts rather than protect an initial theory.
The NYC DCAS Investigator notice lists abilities such as complex problem solving, planning and organizing, written expression, number facility, spatial orientation, and familiarity with common office software. Exact competencies vary by title and agency.
What strong answer review looks like
After every miss, identify whether you overlooked a fact, assumed something not in evidence, skipped a verification step, or chose an action outside the investigator's authority. Repeat the same skill with a new scenario.
Use a timed set only after you can consistently identify the controlling fact. Speed should improve organization, not replace it.
Verify the hiring path
Check the current notice for qualifications, testing method, passing rules, list procedures, background requirements, and any software or writing assessment. Do not treat a practice score as an official ranking.
