Does the online Lean training include (practical) certification?

Yes, every online Lean training we offer includes certification. Upon successful completion of the training, you will receive an internationally recognised Lean certificate from Cardiff University.

This also applies to the Lean Green Belt and Lean Black Belt courses, which include your practical certification.

We guarantee full transparency: there are no hidden fees or the need to purchase additional training to obtain your certificate. Your investment covers everything needed to certify both the theory and practice of Lean.
