5S Practice Test

The 5S Practice Test is a free intermediate-level, 20-minute skill test from Science of Apps. It tests 5S workplace organisation knowledge — the five steps and their Japanese terms, implementing sort and set in order with red tags and visual management, shine, standardise and sustain with audits, and how 5S supports safety, lean and continuous improvement — written to the Lean Enterprise Institute's Lean Lexicon and ASQ quality guidance for 2026. Score 70% or more on its 20 questions to earn a verifiable 5S Readiness certificate (SOA-5S). Every question is based on published standards and research — including What are the five S's (5S) of lean (ASQ), What is Lean? (Lean Enterprise Institute), Quality resources (ASQ) — and each answer is explained with its source.

Science of Apps offers a free 5S Practice Test, updated for 2026 and 2027. It measures the five steps, implementation, sustain, audits and leadership and 5S, safety and lean and gives instant results with a shareable certificate.

Read the four skill areas on this page, then take the 20-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 5S 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: What are the five S's (5S) of lean (ASQ); What is Lean? (Lean Enterprise Institute); Quality resources (ASQ). 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: The Five Steps (Sort and set in order, Shine and standardise and Sustain); Implementation (Red tags, Visual management and Layout); Sustain, Audits and Leadership (Audits, Leadership and Habits); 5S, Safety and Lean (Waste, Safety and Continuous improvement). Every question is an original scenario written to the 2026–2027 standard, with the published source named under it.

Production operator or team leader, Lean or continuous improvement coordinator, Warehouse or maintenance supervisor, Quality technician and Office or healthcare improvement lead. It suits anyone who wants a quick, verifiable way to show 5S knowledge in 2026 and 2027, from students and career switchers to experienced professionals.

5S stands for Sort (Seiri), Set in order (Seiton), Shine (Seiso), Standardise (Seiketsu) and Sustain (Shitsuke). Together they create a clean, organised and visual workplace where problems and waste are easy to see.

6S adds Safety to the five steps, making hazard identification and control an explicit part of workplace organisation. Many organisations use 6S so safety checks are built into routine 5S audits.
