The Workplace Investigation Certification is a free intermediate-level, 20-minute skill test from Science of Apps. It tests workplace investigation skills — planning, scope and fair process, investigative interviewing, evidence gathering and credibility assessment, and findings, reports and follow-up — written to the Association of Workplace Investigators' Guiding Principles, Acas investigation guidance and Code of Practice, US EEOC harassment guidance and the PEACE interviewing model for 2026. Employment law varies by country; follow local law and policy. Score 70% or more on its 20 questions to earn a verifiable Workplace Investigation Proficiency certificate (SOA-WI). Every question is based on published standards and research — including Guiding Principles for Conducting Workplace Investigations (Association of Workplace Investigators), Harassment (U.S. EEOC), Investigations for discipline and grievance: step by step (Acas) — and each answer is explained with its source.

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: Guiding Principles for Conducting Workplace Investigations (Association of Workplace Investigators); Harassment (U.S. EEOC); Investigations for discipline and grievance: step by step (Acas); Acas Code of Practice on disciplinary and grievance procedures (Acas); What is GDPR? (GDPR.eu). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Four skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: Planning, Scope and Fair Process (Impartiality, Scope and Interim measures); Investigative Interviewing (Approach, Questions and Support); Evidence and Credibility (Documents, Digital evidence and Credibility); Findings, Reports and Follow-up (Findings, Reports and Actions). Every question is an original scenario written to the 2026–2027 standard, with the published source named under it.

It suits anyone who wants a quick, verifiable way to show Workplace Investigation knowledge in 2026 and 2027, from students and career switchers to experienced professionals.

A fair investigation is prompt, impartial and thorough. The investigator has no conflict of interest, gives the person accused a chance to respond to the allegations, gathers relevant evidence from all sides, keeps information as confidential as possible and reaches reasoned findings.

Most workplace investigations use the balance of probabilities (in the US often called the preponderance of the evidence): whether it is more likely than not that the alleged conduct happened. It is a lower standard than the criminal "beyond reasonable doubt".
