Six Sigma Green Belt

Our Six Sigma Green Belt Online Training Program has been used by thousands of students to learn the essential elements of a Six Sigma program. This interactive online program provides the training you need to master these highly valuable skills and participate effectively in credible Six Sigma programs.

This online certification program is offered in partnership with major colleges, universities, and other accredited education providers. Successful completion of the Green Belt course and the final exam provides a Green Belt Certification without Projects. Green Belt students participating in Six Sigma projects sponsored by their management may submit Green Belt Assessment Forms, completed by your project sponsors and team members, to their instructor for consideration towards the full Green Belt Certification (with projects).


  • By completing this program, you'll be able to:
  • Recognize key attributes of a successful Six Sigma program
  • Appreciate project selection criteria
  • Realize the role of a Green Belt in the Six Sigma organization
  • Understand fundamentals of the DMAIC problem-solving methodology
  • Apply basic Six Sigma tools for Six Sigma project definition and process baseline, including statistical process control (SPC)

  • Actively participate in a Six Sigma team


Six Sigma is a quality improvement methodology structured to reduce product or service failure rates to a negligible level (roughly 3.4 failures per million opportunities). Six Sigma companies typically spend less than five percent of their revenues addressing and repairing quality problems, so that resources are better allocated to meeting customer needs.

To achieve these levels, the Six Sigma process encompasses all aspects of a business, including management, service delivery, design, production, and customer satisfaction. As a philosophy, Six Sigma drives business culture, primarily through the use of Six Sigma projects designed to achieve the organization’s strategic objectives. These cross-functional projects, sponsored by management, are chartered to achieve specific objectives related to quality, schedule and/or cost in a relatively short time period (usually 4 to 6 months). The projects are implemented by cross-functional teams, to improve sharing of information and increase organizational buy-in. Green Belts provide the process expertise needed for the team, which are usually led by more highly-trained Black Belts. (See also our highly-acclaimed Black Belt course).

The Six Sigma Green Belt Online Training Program provides you with an overview of the Six Sigma concepts and tools, including Six Sigma deployment practices, project development, and the DMAIC problem-solving approach. Once you’ve completed this program, you’ll be ready to successfully participate in a Six Sigma team.

This program/course is a good choice for those looking for project management experience and those aspiring to obtain a credential from PMI. It's also an excellent choice for existing PMI credential holders looking for an approved activity for continuing certification PDUs. At the end of this course, you'll be eligible to receive 100 PDUs, which is the equivalent to 100 program hours. You will need to create an account on and add this course to your account in order to qualify for 100 PDUs. ed2go is an approved provider, R.E.P. #3213. Please visit to learn more about PMI credentials and how they may fit into your continuing education plans. (This course aligns to the PMI Talent Triangle™.)

    "The course was very well laid out. This is the first time I took an online course and I found it very easy to navigate and follow. The information on-line was well complimented and supported by the additional resources provided (e.g. books, spreadsheets, etc.) The quick tests and unit tests were fair yet challenging. I truly feel that I've earned my green belt! Thank you!" 
- R.R., California State University, East Bay
