ABOUT YOUR INSTITUTE

How Can International Six Sigma Institute™ Help You?

International recognition. Accessible education. Your professional success.

You want your Six Sigma skills to count in your career. We’re International Six Sigma Institute™, an independent institute helping organizations and professionals earn world-renowned, recognized certifications and prove their competence. We help professionals worldwide build careers and companies sell their outstanding products and services.

International Six Sigma Institute™ is an officially registered organization. Its registered purpose expressly includes professional skills development and certification, with education in both business and IT. We align our internal operations and the way we serve clients with two international standards for certification bodies. ISO/IEC 17021-1:2015 covers bodies that audit and certify management systems. ISO/IEC 17024:2026 covers bodies that certify individuals. Together, our registered purpose and these standards underpin our ability to educate, train, and certify professionals and enterprises.

Why We Built This Institute

Six Sigma is an open problem-solving and quality-improvement methodology that works with other business and operational methods. Yet before International Six Sigma Institute™ was founded for you, professionals had no reasonable way to earn certifications and prove their competence. Six Sigma and quality assurance professionals paid expensive fees for other entities’ one-sided, profit-driven programs.

Accessible Programs Built by Experts

Your Six Sigma knowledge deserves recognition without unreasonable classroom training and exam fees. We work to remove those barriers in developed and emerging markets while giving your learning a strong foundation. A consortium of renowned business and team leaders, Six Sigma coaches, mentors, experts, and authorities from all major industries designed our 8 major online Six Sigma certification programs.

A little over a year ago, I was given a link by a United States Army colleague for the Six Sigma Institute. This link was sent to many of us in hopes that we would take advantage of the opportunity. I looked into the programs and found them extremely user-friendly and very practical.

As a result, I decided to start with the Certified Six Sigma Yellow Belt (CSSYB) and Certified Six Sigma Green Belt (CSSGB) certification programs. From there, I eventually completed the other certifications as well.

Several months ago, while attending a military course at Fort Knox, one of the main instructors took about 20 minutes to explain these programs to the students in the class. He had also achieved Six Sigma certifications.

The main instructor explained to the class that: After he completed his Certified Six Sigma Black Belt certification program from Six Sigma Institute, he received numerous job offers that include a prestigious position at Amazon Incorporation.

It is no secret that the United States Army utilizes Six Sigma Certification Programs from International Six Sigma Institute™ on a regular basis.

It is cost-effective and gets straight to the point. I often tout this program to peers, and I will continue to do so.

First of all I want to thank for your site that I learnt quite a lot. I think, your content is very complete and gave us enough support to comprehend Six Sigma Methodology. Nowadays I am implementing Six Sigma Methodology in my project, and thanks to your training program I quickly realized where I am doing good, where I can further improve. Your program contributed huge benefit to my knowhow and experience.

Overall, this is my best online certification experience so far!
The lifetime valid Six sigma Certifications from your Institute is really simple, easy and worth to its online registration, reading material and the test. The text and diagrams explain all aspects of Six Sigma very clearly leaving no room for doubts.
I got a thorough overview of the concepts which I'm rather sure of retaining (for lifetime!) and could relate to the real-projects well. As Consultants we have been doing projects along similar lines. The concepts tie these activities and roles into a Six Sigma Methodology that is more appreciated by the industry.
I wish International Six Sigma Institute many more such achievements in the future. Everything exceeded my expectations. I would definitely recommend International Six Sigma Institute to others who want to either complement their experience with certification or begin Six Sigma projects after certification.
