If you’ve been researching Lean Six Sigma certifications, you’ve probably run into phrases like “accredited,” “recognized,” or “internationally accepted.” It sounds official, but here’s the truth: there’s no single governing body that accredits Six Sigma worldwide.

Unlike becoming a CPA (where there’s one exam and one accrediting body), Lean Six Sigma is an open framework. That means different organizations can create their own training and certification programs. Some are excellent. Some are… less so.

Here’s what you need to know so you don’t get misled:

There’s No Official “Six Sigma Accreditor”

• ASQ (American Society for Quality) is well known, but they don’t “own” Six Sigma. They offer their own exams.
• IASSC/PeopleCert (based overseas in Cyprus) runs proctored exams, but they aren’t a universal standard.
• Universities and corporate training providers often have their own Six Sigma programs.

So when you see a provider say they are “accredited”, it usually means they’re either:

1. Accredited by a training industry group (not Six Sigma-specific), or
2. Using the word as marketing, not in an official sense.

What Employers Actually Care About

Most hiring managers aren’t looking for a specific “accreditation stamp.” They want to know:

• Do you have the skills to apply Six Sigma?
• Is the program from a credible source (university, reputable provider, well-recognized partner)?
• Can you demonstrate results from using the tools?

In other words, your ability to do the work carries more weight than the logo on your certificate.

Red Flags to Watch Out For

• Providers that push “accreditation” as their main selling point. Often, it’s because the substance of their training is weak.
• Programs that promise you can earn a Belt in 3–5 hours. Employers know that’s not realistic.
• No name of any instructor or people behind the training or provider offering the program.
• Hidden fees for exams, renewals, or retakes. A credible provider should be transparent.

Another red flag worth mentioning: there are a few so-called “accreditation” sites in the Six Sigma space that were actually created by the same individuals who own separate Six Sigma training companies. In other words, they built their own accrediting body to accredit themselves, and then use it to funnel traffic back to their courses.

It looks official at first glance, but it’s really just a marketing tactic. If you take a few minutes to research who runs these sites, you’ll often find the connection. That’s why it’s important to look beyond the word “accredited” and focus on transparency, credibility, and real recognition.

One more thing to watch for: many of these “accreditation” sites list universities or other training providers on their websites as if they are officially accredited. In reality, those logos are often used without permission. In fact, many of the universities listed have no idea they are even being advertised this way. If you’re unsure, the best thing you can do is check whether the university itself publicly lists the relationship. If they don’t, that should raise questions. Always think it through and make sure you understand the full story before taking an accreditation claim at face value.

How to Choose Wisely

Instead of chasing “accreditation,” look for:

• Named instructors or experts behind the program (not generic content).
• Courses that include practical tools and examples you can actually use.
• Recognition through partnerships or clients in industries you care about (healthcare, government, supply chain, etc.).

Takeaway

Six Sigma doesn’t have a single accrediting body. What matters is credibility, quality, and applicability. If a provider’s biggest pitch is “we’re accredited,” take a closer look at what that actually means.
