Level 1 certifications, sometimes referred to as yellow belts or bronze level, require the learner to complete a prescribe curriculum (typically a basic level of understand). Level 1 requires the learner to:

• Pass series of tests to confirm that knowledge has transferred and that the learner has retained the key points of the training

Many organizations also choose to require the learner to participate in at least one Lean event / activity before receiving their Level 1 certification.

Level 2 certifications, sometimes referred to as green belts or silver level, require the learner to complete Level 1 and a prescribe curriculum (a limited set of advanced topics). Level 2 requires the learner to:

• Pass series of tests to confirm that knowledge has transferred

• Execute projects that demonstrate a capability has been established within these advanced topics. The projects used to demonstrate capability will be reviewed by the instructor at key checkpoints within the project and as a final completed project

Often a peer review process will also be established for Level 2 Certification.

Level 3 certifications, sometimes referred to as black belts or gold level, require the learner to complete Level 2 and a prescribe curriculum (a set of advanced topics). Level 3 requires the learner to:

• Pass a series of tests to confirm that knowledge has transferred

• Execute projects that demonstrate a capability has been established within these advanced topics and demonstrate capabilities that reflect a depth of knowledge related the application of the Lean principles

The projects used to demonstrate capability will be co-facilitated with an instructor to:

• Confirm knowledge

• Capability

• Facilitation skills

Often conducting peer reviews and coaching are also included in Level 3 Certification.
