Why These Exams

Built by trainers.
Not algorithms.

Every question was written by Enviso's training team — professionals who have delivered Lean Six Sigma programmes internationally for over two decades, and who know exactly where candidates stumble in official ILSSI, IASSC, and LSSIAP examinations.

🎯
Certification-aligned topics
Questions map directly to the syllabus topics that ILSSI, IASSC, and LSSIAP certification bodies examine. No filler, no trivia — only the content that determines your result on the day.
📊
Real exam conditions
Timed, closed-book, all-questions-mandatory. The format mirrors the actual certification exam so there are no surprises. A 70% pass mark — the same threshold used by the certification bodies.
🧠
20 years of trainer insight
Enviso has trained thousands of professionals across Europe and beyond. The questions reflect the misconceptions, gaps, and edge cases that our trainers see repeatedly — the ones that separate a pass from a fail.

Common Questions

FAQ

Are these exams the same as the official ILSSI / IASSC exams?
No — these are practice exams, not official certification exams. They are designed to prepare you for the official exams by covering the same topics and applying the same pass mark threshold (70%). To obtain a certification, you need to register with the official certification body (ILSSI, IASSC, or LSSIAP).
How accurate are these exams as preparation tools?
Very accurate. Every question was written by Enviso trainers who have delivered official ILSSI-accredited programmes for over 20 years. The topics, difficulty level, and question style closely mirror what certification bodies test. Candidates who score above 80% on these practice exams consistently perform well in official examinations.
Do I need to register or create an account?
No. All four exams are completely free and require no registration, no email, and no login. Simply click the exam you want to take and begin immediately.
What does the coaching report include?
After submitting your exam you receive: overall score and pass/fail result; topic-by-topic performance bars labelled Strong, Developing, or Needs Work; a personalised coaching narrative based on your score; priority study cards for your weakest topics with specific guidance on what to review; and a complete answer review with the correct answer and a detailed explanation for every question.
Can I retake an exam?
Yes — as many times as you like. Each retake starts fresh with the same question set. There is no limit and no cost.
Which level should I start with?
If you are new to Lean Six Sigma, start with Yellow Belt. If you have attended a formal Green Belt or Black Belt programme, go directly to that level. The Lean Practitioner exam is ideal if your focus is on operational Lean tools rather than Six Sigma statistics.
