Who this family is for


Lean Six Sigma certifications are designed for professionals in operations, quality, continuous improvement, and process-driven roles—across government, education & workforce programs, and regulated/process-intensive organizations. Programs can be taken individually or delivered in cohorts as part of a broader improvement effort.

Accreditation & certification


These courses are delivered in partnership with VMEdu using accredited course content and platforms. Trinity provides training and enrollment support; credentials are issued by the respective certification bodies/brands upon meeting their requirements. Trinity does not issue credentials directly.

For organizations and teams

  • Map Yellow / Green / Black Belt levels to specific roles in your agency, department, or plant.

  • Run cohorts aligned to real projects and operational priorities.

  • Combine Lean Six Sigma training with The Trinity Organizational Excellence Diagnostic™ and implementation support to ensure certifications translate into visible improvements.

If you’re considering Lean Six Sigma as part of a broader improvement plan, we can start with a brief readiness conversation to align scope, roles, and expected outcomes.

Lean Six Sigma Black Belt (LSSBB™)

You're senior enough that the operational outcomes you're held to don't fit inside a single project — they live across a value stream. LSSBB is the credential that matches that scope.

Lean Six Sigma Green Belt (LSSGB™)

You've discovered Six Sigma doesn't fix everything by itself. The waste and the variation usually live in the same process, and you need both toolkits to actually solve the problem.

Six Sigma Black Belt (SSBB™)

You've delivered Green Belt projects. Now you're being asked to lead them — to pick the projects, run the teams, defend the results to leadership, and explain why the savings number on your slide is the real one.

Six Sigma Green Belt (SSGB™)

You're going to run an improvement project at work and someone needs to teach you what DMAIC actually does — not how to recite the letters, but how to use it to find the cause of a problem and fix it.

Six Sigma Yellow Belt (SSYB™)

You've heard 'Six Sigma' in three meetings this month and you don't have a working definition for it. SSYB is the no-cost answer — and the cleanest way to find out whether the paid belts are worth your time.
