TMMi Professional

TMMi Professional null

The TMMi Professional certification validates theoretical knowledge of the Test Maturity Model integration (TMMi) and the business reasons for test process improvement. It is intended for people who work with the model, including test process improvers, test consultants, TMMi (lead-)assessors, test managers, and Test Process Group members, as well as stakeholders who need a clear understanding of TMMi.

The level focuses on knowledge and understanding (K1-K2), not assessment execution, and is a prerequisite knowledge level for those aiming to become an accredited TMMi Assessor or Lead Assessor.

TMMi Professional covers the theoretical foundation of Test Maturity Model integration (TMMi) at K1-K2 levels only (remember and understand, not apply). Candidates learn to:

  • Explain why organizations invest in test process improvement, including business reasons, what parts of testing can be improved, and typical TMMi costs and benefits.

  • Summarize the TMMi background, including the structure of CMMI V1.3, testing-relevant aspects of CMMI V2, staged vs continuous representations, key sources used to develop TMMi, the Gelperin and Hetzel testing evolution, and TMMi scope as lifecycle independent.

  • Describe TMMi maturity levels and process areas, and how they fit together.

  • Explain the TMMi model structure, including required, expected, and informative components, generic goals, institutionalization (GG2 and GG3), and the relationship between TMMi and CMMI V2.

  • Summarize process areas, goals, and recognize practices across TMMi Levels 2-5, plus how TMMi is interpreted in Agile, how assessments support improvement (informal vs formal and the generic process), and the phases for implementing TMMi (initiating, diagnosing, establishing, acting, learning).

TMMi Test Process Improver

TMMi Test Process Improver null

TMMi Test Process Improver is an advanced qualification for experienced test professionals involved in test consultancy and test process improvement. It focuses on applying the TMMi Model to plan, initiate, and manage a test improvement project, including implementing TMMi-based improvements and supporting adoption within an organization or project.

Compared with entry-level TMMi knowledge, this level emphasizes practical process improvement and assessment skills, helping candidates lead structured maturity improvements and demonstrate recognized expertise to employers and stakeholders.

TMMi Test Process Improver focuses on the skills needed to support organizations in TMMi-based test process improvement. Candidates learn to:

  • Initiate, plan, and manage a test improvement project using the TMMi Model.

  • Assess the current test process and identify improvement priorities, including how assessments support improvement work.

  • Select and implement TMMi-based improvements within an organization or project, linking improvements to stakeholder needs and expected business value.

  • Support adoption and sustainment of changes by guiding teams through improvement actions and follow-up.

Certification

TMMi Certification Path

TMMi (Test Maturity Model Integration) is a framework that helps organisations improve their testing processes. The certification path supports both individuals and organisations that want to work with the TMMi model.

1. TMMi Professional

This is the starting point for individuals.

You learn the TMMi maturity levels, process areas, and how organisations improve their testing practices.

After the exam, you receive the TMMi Professional certificate, confirming your understanding of the TMMi model.

2. Assessor & Lead Assessor Path

Experienced professionals can continue with assessor training.

Assessors participate in official TMMi assessments and evaluate how organisations apply testing practices using the TMMi model.

3. Organisational Certification

TMMi also offers certification for organisations.

Companies can be assessed at maturity levels 2 to 5, showing that their testing processes follow structured and improving practices.
