This includes people in roles such as as test process improvers, test consultants, TMMi (lead-)assessors, business stakeholders, test managers, and members of a Test Process Group.

TMMi Professionals are individuals who have demonstrated an understanding of the TMMi model and its application to a standard defined in the TMMi Professional syllabus. In order to illustrate this, candidates must pass a formal exam.
