Greece Lean Six Sigma is a PeopleCert Accredited Training Organisation (ATO) and prepares you for the Lean Six Sigma IASSC® certification exams at Yellow, Green and Black Belt.


IASSC (International Association for Six Sigma Certification) is an independent third-party certification body: it certifies a candidate's knowledge against a common Body of Knowledge, regardless of where they trained.
IASSC exams are available through PeopleCert, a global body for certifying professional skills.
See each exam description on the PeopleCert website:
The body that certifies you is different from the one that trains you, so the certification assesses your knowledge objectively.
IASSC exams are delivered through PeopleCert. We guide you through registration and preparation.
All are internationally recognised bodies. We help you choose based on your industry, country and career goals.
