The IASSC Lean Six Sigma Black Belt Study Guide is a free, quick-reference list of essential material to prepare for and pass the certification exam. It is derived from the IASSC Universally Accepted Lean Six Sigma Body of Knowledge for Black Belts. In other words, this is what they say you need to know to pass their exam.

Speaking of passing their exam, did you know that 100% of the people who pass my Green Belt practice exams report passing their exam (IASSC, ASQ, Villanova, etc) on the first try? **Sign up here.** 100% refund inside first 30 days.

**Levels of Cognition based on Bloom’s Taxonomy – Revised (2001)**

These levels are from “Levels of Cognition” (from Bloom’s Taxonomy – Revised, 2001). They are listed in order from the least complex to the most complex.

**Remember**:
Recall or recognize terms, definitions, facts, ideas, materials, patterns, sequences, methods, principles, etc.

**Understand**:
Read and understand descriptions, communications, reports, tables, diagrams, directions, regulations, etc.

**Apply**:
Know when and how to use ideas, procedures, methods, formulas, principles, theories, etc.

**Analyze**:
Break down information into its constituent parts and recognize their relationship to one another and how they are organized; identify sublevel factors or salient data from a complex scenario.

**Evaluate**:
Make judgments about the value of proposed ideas, solutions, etc., by comparing the proposal to specific criteria or standards.

**Create**:
Put parts or elements together in such a way as to reveal a pattern or structure not clearly there before; identify which data or information from a complex set is appropriate to examine further or from which supported conclusions can be drawn.

Is there a complete printed Black Belt IASSC study guide or not?

Many thanks,

Davide from Italy

Hi Davide, I do not currently offer one. What would you like to see in it if I made one?

I’m looking for a Black Belt IASSC study guide too.

Many thanks,

Milan

Hi Milan,

I am currently creating a Black Belt product that will serve both ASQ and IASSC established bodies of knowledge. It will be ready very soon.

If you’d like to be on the notification list for when it’s ready, just take a moment and fill out this very quick survey here and leave your email in the optional field.

The survey will also give you a preview of what will be delivered. Black Belt interest survey:

Also, don’t forget you can sign up for my BB free trial and get access to a few assessment exams here

They will help you see where you need the most help and guide you to a higher score on the exam. (If you’ve already signed up, tell me how you did on the assessment exams.) Best, Ted

sir,If we considered India, then IASSC is recognized ?

Absolutely! Each year at the Global conference many India-based practitioners and companies are represented.

Hi Ted,

please note that I am interested to receive IASSC Black Belt guidance as I failed in the first attempt and I want to apply for the second trial,

please can you advise.

Hi Mayssa,

Do not worry. These tests are difficult and many, many people fail the first time.

My best recommendations are as follows:

How I passed my ASQ Black Belt.

How I passed my Villanova Black belt

How Dana passed the IASSC Black Belt

Hi Ted

Thank you for your prompt reply, kindly I need to ask you can you please give more examples with regards to the DPU, DPMO, TPY and FPY? is there any typical IASSC Black Belt exercise you can share on such?

In addition, you have previously mentioned that you are preparing for the IASSC black belt guide, is it difference from what is available in this BoK page?

Appreciate your prompt feedback as I am planning to apply for my second trial in the coming month…

Thank you in advance for your help and support

Lots of questions here, Mayssa. I love it. Let me dive in.

Not a problem. See the Process Performance Metrics article here. For questions on the same, please see the study guides.

I am currently creating a Black Belt product that will serve the established bodies of knowledge (ASQ, IASSC, Villanova, etc). So, yes, it will cover everything on this page plus everything on the ASQ Black Belt BOK plus the Villanova Black Belt BOK. It will be ready shortly.
