TMMI Exams

The HTB the TMMi Foundation official Hungarian representative in January 2018! But what is TMMi? The TMMi Foundation is a non-profit organization with headquarters in London. It is designed to support companies in software development, primarily in testing, to achieve higher quality and efficiency. For this, they developed a widely accepted, widespread and independent framework, the Test Maturity Model integrated.

As the local representative, the purposes and roles of HTB are:

  • the widespread introduction of TMMi (surveys, certification scheme, industry-specific survey averages)
  • to promote and provide TMMi training and exams in Hungary
  • the training of TMMi auditors
  • to issue certificates in Hungary


Dr. Katalin Balla, founding and regular member of HTB, extended her status as TMMi Lead Assessor until September 30, 2026. Her certificate number is BLLK-610698


Maturity Levels of the TMMi Model

The TMMi model looks at software testing at different maturity levels, with the starting assumption that all organizations start at TMMi level 1 of the maturity ladder. The more mature an organization’s testing practices, the higher the level of maturity the organization fulfills.

The model interprets the stages of development by levels, through which the organization gradually develops from the level of "unmanaged" activities to the "managed", "defined", "measured" levels and up to the "optimized" level. (See figure.)

Test process improvement efforts are focused on the needs of the organization in the context of its business environment. Moving through the different maturity levels increases the capability of test and software quality management to align with the needs of the business or project. The benefits being among others improved software product quality with fewer defects.

This includes people in roles such as testers, test managers, test leaders, process developers, business managers, consultants and auditors.
