For portfolio forms and guidelines, see the Preparing for Certification page.
Gold–level candidates are expected to mentor and/or coach others in the principles of Lean. While it is every Lean practitioner's responsibility to apply Lean tools and techniques, Gold candidates are expected to seek out others on the lean journey and help them develop and grow — to apply Lean knowledge, share that knowledge with others, and develop the community of professional Lean practitioners. Gold candidates are in essence sensei's — ones who have gone before. Their role is to both teach others and continue their own learning. Additionally, it is through mentoring/coaching that future Gold–level candidates will be born.
Mentoring and/or coaching should be demonstrated as a planned activity, with measurable outcomes, and reported as such in the portfolio.
Candidates at this level are expected to interview with a team of Lean Certified professionals and/or program oversight committee who will evaluate the candidates applied knowledge related to the portfolio evidence presented.
