The TMMi Professional certification is aimed at anyone involved in using the TMMi model.
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.
The TMMi Professional exam is comprised of 40 multiple-choice questions. Each correctly answered question is worth one point. A score of at least 65% (26 or more points) is required to pass.
