Six Sigma Certification Exams

Independent Assessments Formally Validating Six Sigma Competency

Lean Sigma Corporation certification exams are formal assessments designed to
validate Six Sigma knowledge and competency at the Yellow Belt, Green Belt, and Black Belt levels.

Why Certification Matters

Professional certification exists to validate competence, not participation. Certification exams provide an objective measure of Six Sigma knowledge and judgment, allowing individuals and organizations to rely on a common standard of competency.

Lean Sigma Corporation exams are designed to assess knowledge at defined levels of responsibility, ensuring certification represents demonstrated competency rather than course completion alone.
