Improvement Practitioner
(Green Belt) Apprenticeship

Lead the delivery of change

Level 4 Improvement Practitioner (Green Belt)

Improvement Practitioners use a blend of Lean and Six Sigma, as well as project and change management principles and tools, to identify and lead the delivery of change across organisational functions and processes.

Typically, Improvement Practitioners lead smaller projects or can play a key supporting role in a larger programme. They tackle issues that may require swift problem solving or re-occurring challenges that require in-depth analysis and the implementation of a range of effective and sustainable countermeasures. They are the focal point for all stakeholders and responsible for communication throughout a project.
