Questions & Answers

Frequently Asked Questions

Everything you need to know about ISSAB certifications

ISSAB offers a structured 5-belt progression (White to Master Black Belt) with industry-standard content, real-world project requirements for Black and Master Black Belt, and professionally designed certificates with online verification. Our certifications are recognised internationally and include lifetime validity — no renewal fees or expiry dates.
Timing varies by student pace. White Belt typically takes 3–5 hours. Yellow Belt 8–12 hours. Green Belt 25–40 hours. Black Belt 50–80 hours. Master Black Belt 80–120 hours. All courses are self-paced with no deadlines, so you can progress at your own speed.
Yes. ISSAB certifications follow international Six Sigma body of knowledge standards and are recognised by professionals and organisations worldwide. Each certificate includes a unique verification code that employers can validate through our online verification system.
No prior experience required. Our White Belt is completely FREE and designed for absolute beginners. Each subsequent belt builds on the previous one, so you learn progressively. Professionals with existing Six Sigma experience may start at a higher belt level.
You have up to 5 attempts per belt exam. If you don't pass on your first try, review the materials and try again. The passing score is 80%. Most students pass within 1–2 attempts. There's no additional fee for retakes.
After enrolment, you get lifetime access to your belt's content through our online platform. This includes comprehensive PDF guides, video lessons, downloadable resources, and practice exam questions. Access is available 24/7 from any device.
Each belt includes structured learning materials (PDFs + videos), unlimited access to course content, an online proctored exam, a professionally designed certificate upon passing, and a unique verification link you can share on LinkedIn and your CV. Black and Master Black Belt also require real-world project submissions.
Belts must be completed sequentially. You must earn your White Belt certificate before enrolling in Yellow, Yellow before Green, and so on. This ensures you have the proper foundation for advanced concepts. However, if you have existing experience, you can test out of earlier levels.
No time limits. Once enrolled, you have lifetime access to your belt's content. Study at your own pace — whether you finish in a week or take several months, your certification remains valid forever once earned.
Every ISSAB certificate includes a unique credential ID and a verification link. Employers, recruiters, or anyone can visit our verification page, enter the credential ID, and instantly confirm the certificate's authenticity. This prevents fraud and makes sharing your achievement on LinkedIn simple and trustworthy.
