Their certification is accepted in all types of organizations like TATA group, Infosys, HCL, Genpact, and many more.
ASQ Certified Six Sigma professional means the professional successfully demonstrated their competence in the subject matters as determined by professionally developed exams based on the ASQ body of knowledge.
ASQ offers a total of 18 types of quality certifications, they are respected and well-recognized across industries. To appear for these certification exams you need to meet the requirements given by ASQ it could be a work-ex requirement or training requirement.
All the certifications have different requirements so I would suggest you check this on the official site of ASQ. For this article, we will focus only on six sigma certification. So when you meet those requirements then you are eligible for the official certification exam.
Then just you have to apply for the exam and prepare for the exam as per the body of knowledge. ASQ offers 4 types of highly reputed Six Sigma certifications and each certification has a different body of knowledge and exam fees –

IASSC Vs ASQ: comparison –
Well from the above discussion one thing I would like to say is that both IASSC and ASQ certifications are well-recognized and respected across the world. Now let’s compare IASSC Vs ASQ on the basis of certain factors to get more clarity.
Compare IASSC Vs ASQ on the basis of Body of knowledge
1. Yellow belt body of knowledge –
ASQ’s Yellow belt body of knowledge includes the 6 sections like Six Sigma foundations, Define, Measure, Analyze, Improve, and Control phase.
On the other hand, the IASSC Yellow Belt Body of Knowledge includes only 3 sections Define, Measure, and Control phase. So here you can prepare for the IASSC Yellow belt exam easily within a short period of time because the syllabus is small.
Just decide your requirement whether you want to prepare for a big syllabus or for a small syllabus because at the beginner level, it is sometimes difficult and time-consuming to prepare for the ASQ YB exam. ( Use these practice tests for IASSC/ASQ YB exam)
2. Green belt body of knowledge –
ASQ Green Belt Body of Knowledge includes the 8 sections like Lean principles in the organization, Design for Six Sigma, Six Sigma organization goals, Define, Measure, Analyze, Improve and Control phase.
On the other hand, the IASSC Green Belt Body of Knowledge includes 5 sections like Define, Measure, Analyze, Improve, and Control phase.
But overall IASSC GB exam syllabus is 95% similar to the ASQ GB exam syllabus, some topics like Design for Six Sigma and Design of Experiments are not included in the IASSC GB syllabus.
You will learn these in the IASSC BB exam. So this is the only minor difference. You can decide whether to go for IASSC or ASQ green belt exam because BOK is almost the same.
You need the same preparation time for both exams also the difficulty level of the exam is nearly equal only in the case of the ASQ GB exam, you need to put a little extra effort to learn topics like Design for six sigma and the Design of Experiments.

3. Black belt body of knowledge –
ASQ’s Black belt Body of knowledge includes the 9 sections like Organization-Wide Planning and Deployment, Organizational Process Management and Measures, Team Management, Design for Six Sigma, Define, Measure, Analyze, Improve, and Control phase.
On the other hand, the IASSC Black belt body of knowledge includes 5 sections like Define, Measure, Analyze, Improve, and Control phase also included the Design of experiments. Both the Body of knowledge is nearly the same, I would say 95% same.
The difficulty of the exam is high and the time required for preparation is also high because you are preparing for the Black belt exam, black belt is the leader of the Six Sigma project so definitely he needs to learn some extra things to manage the project successfully.
For the Master black belt, you should definitely go for ASQ certification, as IASSC does not provide the master black belt certification. This is the highest level of certification and it is a very difficult exam, to achieve this you need years of experience as well as you have to do high-level study.
Let me conclude this point, overall ASQ exams are more difficult than the IASSC exams, ASQ exams are mostly application-based while IASSC exams are theoretical as well as application-based. I hope you got this point. Let’s see the next factor.
Compare IASSC Vs ASQ on the basis of Exam format
1. Yellow belt exam –
IASSC Yellow belt exam format –
ASQ Yellow Belt exam format –
IASSC Green Belt exam format –
ASQ Green belt exam format –
IASSC Black Belt exam format –
ASQ Black belt exam –
An important observation from the above discussion –
- IASSC offers Lean Six Sigma certifications while ASQ offers only Six Sigma certification. You can decide whether you want to become Lean Six Sigma certified or Six Sigma certified as per your requirement.
- All the IASSC certification exams are closed book (that means you have to memorize BOK and one reference document is given to you that includes formulas) and exams are conducted on computers only (online mode).
- While ASQ certification exams are open book (you can use reference material during the exam) and conducted using the computer as well as pencil-paper (offline mode).
- For all the IASSC certifications you have to recertify after the validity period ends and again appear for the exam to earn certification. On the other hand, ASQ green and yellow belt certifications are lifetime certifications but for ASQ Black belt certification you have to recertify after every 3 years.
- Overall ASQ exams are lengthy and need a huge amount of preparation as compared to IASSC certification. These observations will help you to make the right decision between IASSC Vs ASQ.
Compare IASSC Vs ASQ on the basis of Certification cost
Certification cost is the most important aspect between IASSC Vs ASQ selection because if you are fresher it is very difficult for you to go for these certifications because of financial problems exceptions are always there, on the other hand, if you are a work-ex guy then you can easily afford these certifications.
If you look at the above pictures of the exam format you will find that all the IASSC certifications are cheaper as compared to ASQ.
Even if you are an ASQ member the certification cost is still high as compared to IASSC, for example, IASSC YB cost is $250 while ASQ YB cost is $322 ( for ASQ members) so there is a difference of $72.
I think freshers can’t afford this much amount of money at the start of their careers so on the basis of certification cost when you are new to this field and want to earn recognized certification to start your career then IASSC YB/GB certification is the best option.
After taking some years of experience as well as you are ready to afford the price of ASQ certification then you can apply for the ASQ certification for different belt levels.

Compare IASSC Vs ASQ on the basis of Exam requirements –
This is another important factor because for ASQ certification you have to meet certain requirements and this is not the case with IASSC certification.
For IASSC yellow belt, green belt, and black belt certification, things like work experience or project application experience are helpful in cracking the exams but are not mandatory.
You need to be aware of body knowledge, and for that, you can do self-study or you can attend the Lean Six Sigma training to understand the IASSC BOK for respective certification.
Similarly, for ASQ Yellow belt certification, you don’t need work experience or project experience because ASQ considers the yellow belt as an entry-level certification that builds foundational knowledge among the employees.
On the other hand for ASQ green belt certification you need 3 years of work experience in one of the areas of ASQ GB body of knowledge. Work-ex must be full-time and paid roles, internship or part-time roles are not considered as experience.
For ASQ black belt certification you need 3 years of work experience in one of the areas of the ASQ GB body of knowledge. Along with that, you require two completed projects with signed affidavits or one completed project with a signed affidavit.
I think for a beginner (not work-ex) IASSC certifications are the best way to start the journey in the Lean Six Sigma field and then after taking project experience and meeting those requirements you can go for ASQ certification.
Now decide where you are right now. whether you have required work-ex or not, depending upon that take your decision between IASSC Vs ASQ. Right!
How to make the final decision between IASSC Vs ASQ?
As we discussed earlier that global certifications are important for a beginner or entry-level employee who just started a professional career journey. These certifications help people to get a promotion and also help people to get a high-paying job. So definitely getting certified is valuable nowadays.
People will tell you that certification doesn’t have any value, your experience matters. Well, I completely agree with them, this is true when you have years of experience but what if when you are fresher?
In that case, any certification is helpful instead no certification because certification will tell interviewers that the person is a continuous learner and he has theoretical knowledge in that respective field.
That’s why I think doing global certification will increase your value in the job market. After becoming certified, you can further increase your value by doing real-time Six Sigma projects and solving real-life business problems.
Here I am not going to tell you which six sigma certification you should do. I will help you to decide between IASSC Vs ASQ with the help of a list of questions that you should ask yourself.
I already told you that both are recognized and respected across the world. So now it’s your time to answer these questions. List of questions –
Just answer these questions and depending on your answers I have already explained to you what should be the best option for you. Validate that information and make your decision. See the below example and do the same for other questions.
For example – Are you a fresher or a work-ex guy?
If Your answer – Yes I am fresher
then the best option – go for the IASSC certification
If Your answer – Yes I have 3 years of work-ex
then the best option – go for ASQ certification
By using these simple questions you can decide between IASSC vs ASQ. From this entire discussion, you understand that you can go for any of these certifications, no need to confuse about which is best between IASSC vs ASQ.
Because both are recognized, just depending on your requirements you need to select the best option for yourself. Feel free to ask your doubts in the comment section.
