IASSC Testing Approach
The International Association of Six Sigma Certification is a recognized international body that certifies Lean Six Sigma Yellow, Green, and Black Belts. The online application process is straightforward.
When to use
When you are ready to sit for an IASSC Lean Six Sigma Yellow Belt, Green Belt, or Black Belt exam, go to the IASSC website and register.
There are many organizations and agencies who provide Lean Six Sigma belt certification. They can be divided into three categories.
One category is companies who have their own internal Lean Six Sigma program. This program often includes internal training and coaching. The company has its own testing and provides certification for internal “belts.” The second category is training and consulting companies who specialized in Lean Six Sigma. Typically these companies have a curriculum and coaching program that they sell to an individual or company. As part of this program, an individual goes through training and/or project coaching. At some point they are eligible to take a test and are awarded the belt that the training company has designated for them. The third category is independent testing or certifying bodies or agencies. In some cases these are national certifying bodies, in other cases they are professional associations. Either way, they establish a body of knowledge based upon input from industry experts and then provide testing and certification to that body of knowledge.
The program is aligned to the body of knowledge from an organization in the third category, the International Association of Six Sigma Certification (IASSC). IASSC does not sell training or coaching. It is strictly a certifying institution. As such they have established a body of knowledge for Yellow Belt, Green Belt, and Black Belt and provide certification testing to proficiency in those fields.
Registration for taking an exam is done through IASSC’s website:
There are no prerequisites to take the exam. When you have mastered the material, you can register and take it. The exams are online computer based exams. They are multiple choice and true/false questions. When registering for the exam you can select a testing center. At this time, IASSC is using PearsonVue testing centers. There are over 8,000 of these located in 165 countries around the world. If you need to take the exam from your home or office, they can make provisions. However, that requires a specific computer capability which changes from time to time as technology advances. So check the website for the current requirements.
The exam is a closed book proctored exam. No calculators or notes can be taken to the exam location. You are able to use the computer’s calculator and IASSC does provide a summary of some of the statistical tables and equations, so you don’t need to memorize those. The passing level for the exam is approximately 77%. However, some of the questions have multiple correct answers and depending upon the number of answers you select, you can get partial credit. Also, some of the questions are weighted heavier than others. So your passing score level could be slightly different depending upon which questions you answered correctly.
The Yellow Belt exam is a two hour exam and contains 60 questions.
The Green Belt exam is three hour exam and contain 100 questions.
The Black Belt exam is a four hour exam and contains 150 questions.
Check the website for the current cost of each exam. At the time this session was prepared the costs were $195, $295, and $395 respectively. But that can change and based upon exchange rates, your amount may be different.
Hints & tips
