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.
