- TMMi Accredited Service Provider have their own TMMi Accredited Assessment Method
- TMMi Recognized Service Provider are using the TMMi Assessment Method, (TAM), developed and provided by the TMMi Foundation

- They may have tools sets / frameworks to assist in improvements after an assessment to reduce time and cost of improvements
2. Accredited TMMi (Lead) Assessors using SCAMPI
The TMMi Foundation has not formally accredited the SCAMPI appraisal method for use on TMMi assessments. However, SCAMPI is recognized as a valid method to perform TMMi assessments.
SCAMPI Lead Appraisers (CMMi Institute certified and part qualified) may apply for TMMi Lead Assessor or TMMi Assessor accreditation provided they meet the defined criteria.
The set of advantages stated above, largely also applied with assessment performed by accredited TMMi (Lead) Assessors using SCAMPI.
3. Self Assessment Using a Accredited Assessment Method
This option involves having at least one TMMi Accredited Assessor (by acquiring the necessary training qualifications and skill) within the organization, in order to license from the TMMi Foundation or Accredited Service Provider an accredited assessment method.
4. Self Assessment without an Accredited Assessment Method
