5. Optional – Attend a classroom review course or register for Lean Online Review Program (LORP)
Review courses are not meant to be training, but a way to understand the Lean Certification exam, organize your reference material, and refresh your memory. You must bring the recommended reading material to the classroom review program or have available for the online review program.
6. Take the exam
The open-book, 170-question exam takes three hours. It is strongly recommended that you bring your recommended reading materials (PDF) to the exam. All exam questions are taken from those sources. You can find exam taking tips here. (PDF)
7. Receive the Lean Knowledge Certificate
When you pass the knowledge exam, you receive a certificate (not a certification) that serves as a base for your pursuit of the Lean Bronze, Lean Silver, and Lean Gold Certifications. It is valid for three years and is not renewable. To earn your certification, you must submit and pass the lean portfolio review.
8. Submit your lean portfolio
To earn your Lean Bronze Certification, you must submit and pass your lean portfolio review. You have three years from the date on your knowledge certificate in which to submit your lean portfolio for review.
Your portfolio should document and include:
- Completion of 80 hours minimum of education/training requirements.
- Five (5) tactical projects: events, projects and/or activities to which specific lean principles and tools were applied*
- A portfolio reflection that captures your personal lean development journey and your reflection about what you have learned through the portfolio and certification process.
Once you have passed your portfolio review, you will receive your Lean Bronze Certification (LBC), which is valid for three years.
Portfolio forms and additional resources can be found on the Preparing for Certification webpage.
*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.
9. Optional – Work with a mentor
Mentoring is an informal relationship between you and someone with more lean knowledge and experience. Seeking a mentor is strongly recommended. To find a mentor, look within your own company. There may be a mentoring program already in place, your manager or supervisor may be willing to take on the role, or there may be a lean leader or champion who can help you.
If you are an SME member, your local chapter may be a source. You may also want to contact one of the Association for Manufacturing Excellence (AME) leaders in your region. You can also join the lean registry for support and mentoring.
10. Plan your next step
Your Lean Bronze Certification is valid for three years. You may choose to pursue recertification or the Lean Silver Certification.
