Undergraduate Certifications

Six Sigma Green Belt


Students are required to take the following courses and earn a grade of ‘B’ or higher in each of these courses to complete the requirements of the Six Sigma Green Belt Certification.

Take both of the following courses:

  • INEN 514: Statistical Analysis for Six Sigma and
  • INEN 566: Six Sigma and Quality Control.

Total: 6 SCH of coursework.

More Information

The cost to take the two required courses is $1,383 per course for a total of $2,766 to complete the Six Sigma Green Belt certification.

Acquiring a Greenbelt certificate enhances a professional skill set and improves an individual’s marketability for obtaining competitive positions with successful organizations and companies. According to Villanova University, “while trained and certified in Six Sigma methodology, a Green belt does not usually practice the methodology full time.” Green Belts can spend up to half of their work time on Six Sigma projects and support Black Belts. They will “use graphs to show process improvement…, create a communication plan to convey accurate information about the project to leadership and other stakeholders, and promote data-driven solutions.”

According to, the largest job website in the world, there are 63,000 jobs related to Lean Six Sigma. The average annual salary for these jobs is over $95,806. states that average Six Sigma Green Belt salaries for job postings nationwide are 42 percent higher than average salaries for all job postings nationwide. Some examples of jobs are Lean Continuous Improvement Leader, Lean Process Improvement Engineer, Supplier Quality Engineer Senior, Lean Manufacturing Facilitator, etc.

Six Sigma Lean Certificate


Students are required to complete six courses to earn the Lean Six Sigma Certificate:

1.       MATH 241: Calculus I, or MATH 220: Applied Calculus, or MATH 222: Business Calculus;

2.       MATH 242: Calculus II or STAT 200: Basic Statistics;

3.       INEN 400: Engineering Statistics I or EMGT 414: Statistical Analysis for Six Sigma;

4.       INEN 401: Engineering Statistics II or EMGT 466: Six Sigma and Quality Control;

5.       INEN 408: Lean Manufacturing and Management Systems or EMGT 411: Theory and Applications of Lean Manufacturing and Management; and

6.       INEN 420: Six Sigma Black Belt Project or EMGT 420: Six Sigma Black Belt Project.

Total: 18 SCH of coursework.

Who Should Pursue the Lean Six Sigma Certificate?

The course requirements allow learners from diverse technical backgrounds to earn the Lean Six Sigma with minimal prerequisites. For example, those who have completed all or part of a mathematics, technology or engineering degree may already have the mathematics and statistics requirements. Industrial Engineering Students at Louisiana Tech University can complete the certificate as they complete their undergraduate degree by taking only one additional course (INEN 420).

More Information

The cost to enroll in the six required courses is $1,261 per course for a total of $7,566 to complete the Lean Six Sigma Certification.

Lean Six Sigma is a method that relies on a collaborative team effort to improve performance by systematically removing waste and reducing variation. Lean Six Sigma not only reduces process defects and waste but also provides a framework for overall organizational culture change.

The term Lean is typically used for process/time focused analyses, and Six Sigma is typically more statistical/defect focused. Lean Six Sigma is the best of both sides; it allows you to bring variation in time performance to control and reduce defects with variability-based improvements. states that the average salary for a Lean Six Sigma Specialist is $110,257 per year in the United States. Some examples of job titles are Lean Engineer, Lean Six Sigma Process Engineer, Quality Manager and Operational Excellence Engineer.
