AI Hallucination Detection Test

The AI Hallucination Detection Test is a free 15-minute skill test from Science of Apps. It tests whether you can spot AI hallucinations — invented facts, citations, quotes, numbers and code — and choose the right techniques to prevent them. Score 70% or more on its 15 questions to earn a verifiable AI Hallucination Detection certificate (SOA-AIHD). Every question is based on published standards and research — including A Survey on Hallucination in Large Language Models (2023) (Huang et al.), Prompt engineering overview (Anthropic), IFCN Code of Principles (International Fact-Checking Network (Poynter)) — and each answer is explained with its source.

Read the three skill areas on this page, then take the 15-minute test online — no fee, course or sign-up. You see every answer explained when you finish. Score 70% or more and you get a AI Hallucination Detection certificate straight away, on screen, as a PDF and by email, with a credential ID anyone can verify.

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: A Survey on Hallucination in Large Language Models (2023) (Huang et al.); Prompt engineering overview (Anthropic); IFCN Code of Principles (International Fact-Checking Network (Poynter)); What is retrieval-augmented generation? (IBM); AI Risk Management Framework (NIST); People + AI Guidebook: Explainability + Trust (Google PAIR). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Three skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: Spotting hallucinations (Fabricated sources and quotes, Wrong numbers and dates and Invented code and APIs); Preventing them (Grounding and retrieval, Prompting for uncertainty and Verification workflows); High-stakes domains (Legal and medical claims, Financial figures and Escalation and disclosure). Every question is an original scenario based on a published standard, official documentation or research, named under the question.

Employers in 2027 need people who can catch AI hallucinations before they cause harm: invented citations and quotes, wrong numbers and dates, made-up code packages and APIs, and confident answers in legal, medical or financial contexts. They also want prevention — grounding, prompts that allow uncertainty, and verification workflows. Editors, analysts, developers and support leads all use the skill.

Nothing. There is no fee to take a test, to receive the certificate, to have it emailed or to verify it, and no sign-up.
