One of the most common questions I get is ‘How much time do I need to study for a six Sigma exam?’ Another common question, not surprisingly is; ‘Can I make it faster?’

“Could you tell us how much time a day or week you put into studying?  I studied for the bar exam 13 hours six days a week for three weeks and passed.  Do I need to put this much time in for my Green Belt.” – Ramona

How Much Time You Need to Learn Six Sigma

This depends on training. I’m not a fan of the 3 day or 5 day courses where trainers charge you or your company a bunch of money and they certify you at the end. Let’s just assume that you’ve signed up for a reputable Six Sigma training program.

How Much Time You Need to Prepare for a Six Sigma Exam

Like all things, this depends upon your level of knowledge going on in. For most people who have had good training, it takes at least 8 weeks of steady effort of a couple of hours a day. Of course if you have more time to spend per day, you can shorten this time. I wouldn’t suggest less than 4 weeks unless you are certain you have an excellent command of the material.

I think this process can be simplified and ‘hacked. ’

I’d start by looking at which topics the exam you are taking favors (Green Belt vs Black Belt; ASQ, IASSC, other).  Here you want to see which topics they have a large percentage of points allocated to. Then compare your scores.

Look at the Weightings

For example, here’s how the ASQ and IASSC Six Sigma Green Belt exams weight topics.

Take a Benchmark Exam

Now that you know how important each section is, next, I’d take a benchmark exam to see how you rate in each section.

Focus on Your Problem Areas

If you did poorly in an area that a large amount of the points are based on, I’d start there.  The example I show above indicates that the candidate only got 17% of the Measure phase questions correct. That phase accounts for 30% of the entire exam! Better start there and study up!

Dive Deep!

But there’s another problem. The Measure Phase has dozens of subtopics. How would you know which subtopics to study? Or, going even further, what kinds of questions in that subtopic stumped you?

You’d have to do a benchmark quiz for the entire measure phase. Then you’d have to do the same for every type of subtopic.

Sounds Like a Lot of Work! How Can I Make it Easier??

If all of this seems incredibly manually intensive, it is. You have to find a ton of questions, stratify them to the topics, and then create your own quiz, take the quiz, then score the quiz. Even after you’re done with all of that you have to divide all of the topics into subtopics and then figure out where the best reference material is to study to bridge the gap.

If you’re interested in such a system, you’re in luck.

The good news is that I have been building a system that does this for you. It will even drill into the topic to find the subcategories you’ve already mastered and steer you to the ones that you need to really focus on for the best return of your time spent.

Hi Previn,

Many people do use my green belt product to prepare for the black belt exams (until I complete the upcoming black belt program).

While the green belt products are not designed for the black belt exams, they are certainly more rigorous than many black belt programs out on the market. The green belt products will help you pass the black belt.

I do offer a 30 day $ back guarantee for all of my products. And I highly encourage you to give it a try. If you’re not convinced it can help you, I’m happy to refund. But the pass guarantee will be reserved for when I release the specific black belt product.

Hi Ray,

There are slight differences between the ASQ and IASSC green belt exams. The body of material that you’re responsible for is largely the same, with a few differences. Although that changes year to year and exam to exam.

Also, mechanically, there are differences. The ASQ exam allows reference material while the IASSC provides you a simple equation sheet.

My site and materials have been created to cater to ALL Six Sigma exams – ASQ, IASSC, Villanova, etc.

There are several reasons for this:

1) The exams are more alike than they are different.

2) Many people end up pursuing multiple certifications across different organizations and it would be silly to charge them twice.

3) While learning the material for a certification certainly meets your need for accreditation, when you use that accreditation for employment, your hiring manager may expect that you have skills that were not explicitly required on your certification. Why not learn them now in the full context of the rest of the material?

For my flagship Pass Your Six Sigma Exam – Guided course, I guarantee that you will pass any greenbelt exam if you follow the instructions, content, and spirit of the course.

Hi Sir,
1.if I do directly the black belt course without green belt .. is it possible ..?

2 .what is the minimum score to pass the black belt exam …?

3.after taken the black belt certificate, which types of jobs I can joint..?

Hi Akila,

Yes, you can become a certified black belt without first getting a green belt certification through many organizations. However, some organizations require you to get a green belt first. This should be one criteria you use in choosing the right certification organization.

The minimum scores change across the various certifying bodies. Generally it’s around 80%.

There are many jobs that a black belt certification opens up for you. You can see a list. Just use your favorite job aggregator (, LinkedIn Jobs, etc) and search on the keyword Black belt.

Approximately how many hours does it take to go through your green belt program? I have my test in a month and wanted to know how much time to devote each day to this program.

This is hard to predict, Kristen. It depends on how much training you received before hand, how much practical familiarity you had with the topics, and sometimes fluency with algebra.

I’ve seen candidates be successful with 2 weeks of preparation while others needed a year.

One way we could look at it is that on average questions might take you 1-2 minutes. There are ~1000 questions in the program so 2000 minutes to be exposed to every question is a good floor. After that it’s getting up to speed on whatever a candidates’ training neglected or they forgot.

Best, Ted
