The open-book 150-question exam takes three hours.
You must provide documentation that you have led a lean transformation of a complete value stream. You must also show that you have led or participated in 5 lean events, projects or activities that applied and integrated lean principles, along with their results.

*Projects should demonstrate continuing practice in lean. For example, if you are applying for certification in 2006, and you started your lean practice in 2001, you may choose to include projects from 2002, 2004 and 2006 in your portfolio to demonstrate that you are still practicing lean.
For portfolio forms and guidelines, see the Preparing for Certification page.
Silver 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, Silver 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. Silver 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 Silver 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.
