ISO/IEC 17025 Practice Test

The ISO/IEC 17025 Practice Test is a free intermediate-level, 20-minute skill test from Science of Apps. It tests knowledge of ISO/IEC 17025:2017 for testing and calibration laboratories — general, structural and resource requirements, process requirements from contract review to sampling and methods, measurement uncertainty, validity of results and reporting, and the management system, audits and accreditation — written to ISO/IEC 17025:2017, ILAC policies P10 and P14 and the JCGM Guide to the Expression of Uncertainty in Measurement for 2026. Score 70% or more on its 20 questions to earn a verifiable ISO 17025 Readiness certificate (SOA-ISO1). Every question is based on published standards and research — including ISO/IEC 17025:2017 General requirements for the competence of testing and calibration laboratories (ISO), International Laboratory Accreditation Cooperation (ILAC MRA) (ILAC), ILAC policy series (including P10 metrological traceability and P14 measurement uncertainty) (ILAC) — 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: ISO/IEC 17025:2017 General requirements for the competence of testing and calibration laboratories (ISO); International Laboratory Accreditation Cooperation (ILAC MRA) (ILAC); ILAC policy series (including P10 metrological traceability and P14 measurement uncertainty) (ILAC); JCGM publications: Guide to the Expression of Uncertainty in Measurement (GUM) and VIM (BIPM). 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: General, Structural and Resource Requirements (Impartiality and confidentiality, Personnel and facilities and Equipment and traceability); Process Requirements (Contract review, Methods and Sampling, items and records); Uncertainty, Validity of Results and Reporting (Measurement uncertainty, Ensuring validity and Reports); Management System and Accreditation (Option A and B, Risks and improvement and Audits and accreditation). Every question is an original scenario written to the 2026–2027 standard, with the published source named under it.

Laboratory quality manager, Laboratory analyst or calibration technician, Technical manager or lab director, Internal auditor for laboratories and Accreditation assessor candidate. It suits anyone who wants a quick, verifiable way to show ISO 17025 knowledge in 2026 and 2027, from students and career switchers to experienced professionals.

ISO/IEC 17025:2017 sets the general requirements for the competence, impartiality and consistent operation of testing and calibration laboratories. Laboratories are accredited against it by national accreditation bodies that are signatories to the ILAC Mutual Recognition Arrangement, so their results are accepted across borders.

Verification confirms that a laboratory can properly perform a standard method as published. Validation is needed for non-standard methods, laboratory-developed methods and standard methods used outside their intended scope or modified, to show the method is fit for its intended use.
