Foreword
ASC-PCS-001:2017 (Revision 1) has been developed by the American Standardization
Council (ASC) to establish mandatory requirements for the accreditation of organizations that
certify personnel in Lean Six Sigma (LSS) methodologies. This standard ensures that LSS
certifications are credible, consistent, and meet rigorous standards of quality and impartiality.
This standard is based on the principles of ISO/IEC 17024:2012, Conformity assessment —
General requirements for bodies operating certification of persons, with specific and
stringent requirements for the LSS field. The designation PCS -001 stands for Personnel
Certification Standard - 001, representing the first in the ASC personnel certification
standards series.
Introduction
The purpose of this standard is to establish strict requirements for organizations providing
Lean Six Sigma certification. ASC accreditation demonstrates that certification bodies meet
the highest standards of competence, impartiality, and reliability.
This standard specifies mandatory requirements for certification schemes, certification
processes, and quality management systems. Compliance with all requirements is mandatory
for accreditation. No deviations or alternative approaches are permitted unless explicitly
stated in this standard.
1. Scope
This standard specifies mandatory requirements for organizations seeking accreditation from
the American Standardization Council (ASC) to operate a certification system for Lean Six
Sigma (LSS) personnel.
This standard applies to all organizations providing certification for LSS personnel. The
scope of accreditation covers the following levels of LSS certification only:
• Yellow Belt
• Green Belt
• Black Belt
• Master Black Belt
Note: White Belt, Champion, and Project Manager certifications are not included in this
revision.
2. Normative References
The following document is a normative reference and is indispensable for the application of
this standard:
• ISO/IEC 17024:2012, Conformity assessment — General requirements for bodies
operating certification of persons
3. Terms and Definitions
For the purposes of this document, the terms and definitions given in ISO/IEC 17024:2012
apply, along with the following:
• Lean Six Sigma (LSS): A methodology that combines Lean manufacturing principles
and Six Sigma quality improvement methods to systematically remove waste and
reduce variation.
• Certification Body: The organization conducting the certification of persons.
• Candidate: A person who has applied to be admitted into the certification process.
• Certified Person: A person who has fulfilled all specified requirements and is
granted certification.
• Scheme: A certification system for specified categories of persons.
• Body of Knowledge (BoK): The complete set of concepts, terms, and activities that
make up the Lean Six Sigma professional domain.
