Our Black Belt upgrade training provides candidates everything they need to lead and implement Lean Six Sigma projects.

Attending our online training sessions requires an additional 20 hours of self-directed study. Study consists of reviewing each video class, completion of worksheets and knowledge retention quizzes. Candidates MUST be Green Belt certified prior to attending Black Belt training.

Thornley Group’s Black Belt training provides all the tools and information required for Lean Six Sigma project implementation and leadership. While the course builds on the DMAIC and Lean principles that are central to process improvement, the Black Belt course focuses on team leadership and project management skills, as well as training with advanced statistical and data management tools.

Our Black Belt certifications are aimed at people who lead business improvement projects or who are responsible for managing improvement teams. 

Using simulation exercises and their own practical experience of our programmes, Thornley Group trainers take candidates through the processes they will need to apply the tools and techniques included in the course.


Candidates who complete the Black Belt course are eligible to take the IASSC exam. For professional credibility, we recommend that candidates participate in projects that deliver significant cost savings, defect reduction or have other major impacts on customer experience. After training, Thornley Group provides 6 months of email support to help candidates coordinate and achieve their projects.

  • Candidates must be Green Belt trained prior to attending a Black Belt course and we will need to verify their training. If you have received Lean Six Sigma training from another organisation, you are welcome to attend the course and take the exam. Due to the inadequate course material seen in the content of some organisations, we cannot guarantee your prior training is sufficient to pass the Black Belt Exam.
  • Candidates must have a working knowledge of algebra and have experience analysing numerical data, such as through Green Belt projects.
  • The ideal Black Belt candidate should have the authority to work on an improvement project with their organisation to improve credibility with prospective employers. The project should be cost-saving, defect reduction or have other customer impacts. Where this is not possible, Thornley Group provides a simulation case study.
