Choosing the best Lean Six Sigma Certification course online that will help you certify for any of the lean six sigma belts can be pretty tricky because there are a lot of great options to choose from. Each Lean Training course has different features and is aimed at slightly different types of individuals, so how can you make sure you get the right one?

The best Lean Six Sigma Certification course depends on you, not what other people say. After all, studying for the exam is no small feat. It will probably take you 5 weeks to get your Six Sigma Green Belt alone. There’s no reason to make that process longer. You want something that will prepare you faster and easier.

Think about what is most helpful to you in your learning process. Did you learn best in school from listening to your teacher lecture, or did you learn best by reading the textbook and answering questions? Both of these are great ways to learn, but keep in mind that each LSS course emphasizes these features differently.

That’s why I reviewed the 7 best Lean Six Sigma certification courses for you. This way you can read about the advantages and disadvantages of each program and compare each LSS study material features, so you can be sure to make the right decision.

Here are the best Six Sigma certification courses online to help you pass the exam and get your Six Sigma Green Belt or Black Belt Certification.

1. MSI Certified Six Sigma Training Course


The Management and Strategy Institute (MSI) has specialized in creating fully online Lean Six Sigma study materials for the last seven years. MSI Certified courses are designed to be flexible and accommodate your busy life by letting your study at your own pace without the rigid structure of traditional classrooms.

MSI courses will help you prepare to get your white, yellow, green, or black belt certifications with all of their different course options that give you up to 12 months to study. It doesn’t matter which level of LSS certification you are working towards, MSI has a course for you. Each course includes extensive written materials and over 400 practice questions covering all of the topics on the exam. In addition, you will get 3 PDUs.

Once you finish your program, MSI will send you a professional certificate and full transcripts that you can frame in your office or send to employers. No other company does this, so it’s pretty cool. Plus, there’s no extra fee for the certification. It’s included with your course purchase!

MSI is not only known for their awesome Lean Six Sigma study materials; they’re also known for their student support. They are one of the few courses that allow you to take a FREE trial of their platform to see if you like it before you buy it. PLUS, they offer a 100% money back guarantee. If you don’t like the course, you can return it within 30 days, no questions asked. That’s pretty awesome. There’s no risk, no hidden fees, and no reason not to at least try it out.

2. GreyCampus Lean Six Sigma Course

Grey Campus PMP Logo

Although not as well-known as other test prep courses available to students, GreyCampus offers a terrific catalogue of project management and quality management courses to aspiring professionals. Because of this, it should come as no surprise that their Lean Six Sigma curriculum would land a high spot on this list!

If you need to learn the basics of Lean Six Sigma, GreyCampus offers a very reasonably priced Yellow Belt prep course. For those looking for the next step up, they also offer Green Belt courses for just a smidge more— in self-paced and live learning options. They also offer Black Belt courses for aspiring experts, with all three belt levels also including a certification exam at the end.

But what sets GreyCampus apart from other Lean Six Sigma prep courses on the market? For starters, they offer great deals on their self-paced study courses. In fact, students interested in going the distance will want to take advantage of their Green & Black Belt combo course to save even more money!

The biggest drawback to this company’s catalog of review materials is their lack of versatility. Although each belt level is covered with a self-paced online course, only their standalone Green Belt study course comes in a live online package. That means that you’re going to have a much tougher time preparing for Black Belt certification if you prefer studying with the aid of a live lecturer.

3. Edx Lean Six Sigma Green Belt Review

Unlike other courses on this list, Edx offers a much more guided approach to teaching you Lean Six Sigma. There is some self study content, but your study calendar is created based on how quickly you intend to complete the live lessons.

As you progress through the course your results will be tracked in a project storybook template. Doing so will let you see how well you’re doing while keeping you engaged with each lesson. It also lets you change your study schedule on the fly based on how well you’re doing. The course pace can be accelerated if you’re responding well to each lesson or slowed down if you need extra time to understand. 

Despite their great materials, it’s important to recognize that Edx only offers Green Belt training for Lean Six Sigma. So if you’re interested in continuing your education, consider finishing up with Lean Sigma Corporation.

Enrollment in this program costs $888— but that price is frequently discounted. Make sure to check this course out if you want to learn project management at the university level!

4. Lean Sigma Corporation Lean Six Sigma Certification Course 

Lean Sigma Corporation has designed their entire course around meeting two different educational requirements for professionals: certification and CPE. Whether you’re completely new to project management and want to learn about Lean Six Sigma so you can start your career, or if you’re an established professional who needs to complete supplementary education to retain your certification, this prep course has you covered.

In order to ensure that the material they’ve created actually teaches you something, Lean Sigma Corporation went the extra mile when it comes to video content. If you’re sick to death of lengthy and static lecture videos, comprised of a professor in front of a white board with bad audio, this course will feel like a breath of fresh air. Everything you need to know in order to pass your certification exam is covered in 21 well-produced and engaging video modules.Understandably, it can be difficult to invest money into a course based only on a positive review. That’s why I encourage you to take advantage of Lean Sigma Corporation’s free demo if you’re curious. This demonstration will give you an opportunity to see what their eLearning system is all about and should help you to decide whether or not this is the right course for your educational needs.

5. Opex Learning

Although it may not directly mention Lean, OpEx Learning’s Green Belt and Black Belt courses can teach you the essentials of Lean Six Sigma methodology. Their entire curriculum is designed to teach practical knowledge, which is also why they heavily incorporate Minitab in their course.

Even if you’re not interested in this specific project management methodology, you can take advantage of their PDU content to cheaply maintain your status for other licenses. Since they’re accredited by the IACET, you can rest assured that hundreds of educational institutions across the globe will recognize your efforts.

With that being said, you won’t have much time to make up your mind. If you sign up for one of their courses, you’ll only have seven days to receive a refund if you’re not satisfied. And with no option for a trial or demo, this can be a riskier pick than something like Lean Sigma Corporation.

6. ExpertRating Six Sigma Prep


ExpertRating offers one of the most affordable 6Sigma review courses on the market, but it is not as comprehensive as other courses. That’s not necessarily a problem for some people though. If you don’t need a lot of study materials and you just need to brush up on some concepts, this is a great study guide that will save you a ton of money. Let’s look at what’s included.

ExpertRating offers training for both Green Belt and Lean Six Sigma Black Belt training certificates. They include more than 200 practice questions along with explanations and solutions. Their materials focus on real-life project scenarios in an effort to help you understand the methodologies and apply them to future questions.

Another great thing about ExpertRating LSS is that they include the certification in the price of the course. All you have to do is pay a small shipping fee and you will get an awesome physical certification in the mail. They also provide transcripts online that you can print or email to anyone you need to.

It also comes with 3 PDUs, a full money-back guarantee, and a free trial offer. There’s no reason not to try it out and see how well it will work for you.

7. Pyzdek Institute Six Sigma Course


The Pyzdek Institute is the industry leader in Lean Six Sigma study materials. They offer the most comprehensive training for all belt certifications out of any course, so if you need more information and study materials, this is the course for you.

Pyzdek’s training program is divided into smaller lessons each with their own goal of teaching you a facet of the DMAIC principles. This is not only an easy way to learn and understand the concepts; it’s also a really efficient way to get through the materials and study topics. Shorter lessons tend to hold your attention longer and help you focus on learning the topics.

The Pyzdek Institute LSS study materials include more than 70 modules, 700 practice exam questions, and graded assignments. It also includes 4 PDUs / 18 CEUs and a 1-year Minitab license depending on which belt you are going for.

Another great feature is the PI works with non-profits to provide Project Coaching and their project-based certification with anywhere between a 4-180 hour commitment depending on your desired belt. To make this possible, they offer a few different subscription levels to choose from allowing you to study with their materials for as little as 30 days and as much as 1 year!

8. iCert Global Six Sigma Study Materials


iCert Global offers both Green Belt and Black Belt Lean Six Sigma study materials led by expert instructors. iCert Global specializes in professional online education and their LSS courses are no different.

Lean Six Sigma Frequently Asked Questions

🤔 How can I get Six Sigma certification?

Although it is possible to earn Six Sigma certification through your school, small training sessions, or even with self-paced materials, one of the most straightforward means of earning it is through one of the major Six Sigma organizations: The Council for Six Sigma Certification (CSSC), American Society for Quality (ASQ), or The International Association for Six Sigma Certification (IASSC)

❓What is Six Sigma training and certification?

Six Sigma is set of organizational tools meant to improve a business’ process capability. Typically this is done to reduce product defects and increase both profit and employee morale. Hence, as a natural consequence of process improvement, company products and services tend to be of much higher quality and customer satisfaction is high. Essentially, Six Sigma works to reduce process variation and increase control of processes in order to achieve results.

💲How Much Does Six Sigma training cost?

Depending on the provider you choose and the level of certification, Six Sigma training courses can cost anywhere from $129 to $1,999, so it’s important to be specific about what your needs are. The primary influencer on the cost of training is the “belt” that you are trying to certify for (White, Yellow, Green or Black). Also keep in mind that there are different sublevels within Black Belt training.
