LCS Qualifications

Qualifications for organisations, consultants and individuals

LCS Certificates of Lean Competency are issued to individuals by LCS accredited organisations or consultants and also directly by the LCS at Level 2 and Level 3 via the Approved Prior Learning & Experience route.

Our seven levels of competency

The LCS qualifications framework has seven competency levels, which range from 1a to 3b. They are grouped into three categories: 1) Fundamental, 2) Technical and 3) Strategic. The levels cover a broad range of competency, from awareness of core principles of lean, right up to strategic lean leadership. An accredited organisation can initially accredit to one or several levels and can add levels to its accreditation at any point. A detailed description for each level is available to make it clear what knowledge and practical capability is required. Read more.
