Lean Silver Certification

Integrate your lean knowledge with leadership experience.

Lean Silver Certification represents your career progression in knowledge and responsibility as you become a senior employee and team leader. At this level, mentoring/coaching is required and confirms your ability to lead and mentor a team in the preparation, design, and execution of value stream transformations.

You’ll study and learn lean from these key modules from the Lean Certification Body of Knowledge (PDF):

  • Module 1: Cultural Enablers (20%)
  • Module 2: Continuous Process Improvement (30%)
  • Module 3: Consistent Lean Enterprise Culture (20%)
  • Module 4: Business Results (30%)

You must first complete the requirements for earning the Lean Bronze Certification before advancing to Lean Silver Certification.

Schedule and Take

The Lean Silver Certification exam is a three hour, open book and open notes exam. It consists of 150 multiple-choice questions mapped to the Body of Knowledge (PDF). Exam questions are taken from the core reference materials. You must submit your Proctor Form and Agreement (PDF) to SME at least two weeks before your scheduled exam date.

Interpret Your Results

To pass the exam, you need to score 75% or higher. After your exam is scored, you will receive official results by mail, which includes an Examination Analysis Report (PDF) that provides a breakdown of your results by knowledge area.

Next Steps

If you passed your exam, congratulations! To receive your Lean Silver Certification you must exercise your lean knowledge by participating in activities in which lean principles and tools are applied. This is demonstrated through the development of a lean portfolio, which must document and include:

  • 160 hours of education and training requirements (PDF) (80 hours earned from Lean Bronze Certification plus 80 additional hours).
  • Three tactical projects and two integrative value stream projects where specific lean principles and tools are applied.
  • Mentoring and/or coaching (PDF) activities.
  • A reflection statement that captures your lean journey and what you have learned through the certification process.

Visit for the portfolio requirements and forms (MS Word), portfolio information and instructions (PDF), writing tips, and additional resources.

Upon passing your portfolio review you will earn your Lean Silver Certification (LSC) which is valid for three years. During this time you may choose to pursue recertification or pursue the Lean Gold Certification.


Lean Silver Certification candidates are expected to seek out others in their lean journey to help them grow and develop. This activity must be demonstrated and include measurable outcomes in your portfolio.
