ISO 26262 Practice Test

The ISO 26262 Practice Test is a free advanced-level, 25-minute skill test from Science of Apps. Practice for ISO 26262 functional safety training and certification exams (such as TÜV and other functional safety engineer programmes) — safety management and the lifecycle, concept phase and hazard analysis with ASIL determination, system and hardware development with hardware metrics, software development, and supporting processes and safety analyses — written to ISO 26262:2018 (Parts 1–12), with ISO 21448 SOTIF and ISO/SAE 21434 context, for 2026. Score 70% or more on its 25 questions to earn a verifiable ISO 26262 Readiness certificate (SOA-ISO6). Every question is based on published standards and research — including ISO 26262 Road vehicles — Functional safety (ISO), MISRA C:2023 guidelines (MISRA), ISO 21448: Road vehicles — Safety of the intended functionality (SOTIF) (ISO) — and each answer is explained with its source.

Yes. Science of Apps has a free ISO 26262 Practice Test built on the current ISO exam outline for 2026 and 2027. It covers safety management and lifecycle, concept phase and HARA, system and hardware development, software development and supporting processes and safety analyses, scores you instantly and issues a verifiable certificate.

Read the five skill areas on this page, then take the 25-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 ISO 26262 Readiness 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: ISO 26262 Road vehicles — Functional safety (ISO); MISRA C:2023 guidelines (MISRA); ISO 21448: Road vehicles — Safety of the intended functionality (SOTIF) (ISO); ISO/SAE 21434 Road vehicles: Cybersecurity engineering (ISO). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Five skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: Safety Management and Lifecycle (Safety culture and plans, Confirmation measures and Scope and parts); Concept Phase and HARA (Item definition, Hazard analysis and risk assessment and Safety goals and FSC); System and Hardware Development (Technical safety concept, Hardware metrics and Random hardware failures); Software Development (Software requirements and architecture, Coding and unit testing and Verification and coverage); Supporting Processes and Safety Analyses (Tool qualification, Configuration and change management and FMEA, FTA and DFA). Every question is an original scenario written to the 2026–2027 standard, with the published source named under it.

Functional safety engineer or manager, Automotive systems engineer, Embedded software engineer, Hardware or electronics engineer and Safety assessor or quality engineer. It suits anyone who wants a quick, verifiable way to show ISO 26262 knowledge in 2026 and 2027, from students and career switchers to experienced professionals.

ISO 26262 is the international standard for functional safety of electrical and electronic systems in series-production road vehicles. Its 2018 edition has 12 parts covering safety management, the concept phase, system, hardware and software development, production, supporting processes and ASIL-oriented analyses, including motorcycles and semiconductors.

In the hazard analysis and risk assessment, each hazardous event is rated for Severity (S0–S3), Exposure (E0–E4) and Controllability (C0–C3). The combination sets the Automotive Safety Integrity Level from ASIL A (lowest) to ASIL D (highest), or QM where normal quality management is enough.

No. It is an independent practice test written to the publicly available ISO 26262 content outline for 2026 and 2027, for checking your readiness before you book the real exam. Passing earns a Science of Apps certificate rather than the official credential.

Yes. The test is online, in English and free everywhere — people take it from India, the US, the UK, Europe, Africa, Latin America and Asia-Pacific. Your certificate is dated with your own local date and can be verified from anywhere at scienceofapps.com/certification/verify/.

25 questions — 5 from each of 5 skill areas — with a 25-minute limit. You need 70% (18 of 25) to pass and 90% for distinction.

We rate it Advanced: assumes years in the role or deep specialist knowledge. It has 25 scenario questions — 5 from each of 5 skill areas — and a 25-minute limit. You need 70% (18 of 25) to pass and 90% for distinction.

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.

On our server, not in your browser. The answers never reach the page until you submit, so a certificate can only be earned by passing. Each certificate gets a unique credential ID stored by Science of Apps.

You see your score for each area and every question with the correct answer and why, with the published source behind it. You can retake after 30 minutes, and the retake draws questions you haven't seen yet.

No. Every certificate is dated, so it always shows when you passed. Retake a test any time for a newer date or a higher score.

Yes. After you pass, Add to LinkedIn opens the Licenses & certifications form with the certificate name, Science of Apps as the issuer, the issue date, your credential ID and the verification link filled in. You can also download it as a PDF or PNG, and it's emailed to you as a PDF.

Every certificate has a credential ID and a QR code. Scanning it, or entering the ID at scienceofapps.com/certification/verify/, shows the holder's name, the certification, the score and the issue date from our records.

No. They are Science of Apps' own assessments of applied skill. They aren't issued by a university or standards body, and they work best alongside a portfolio that shows the skills in real work.
