TTI receives CARF accreditation

TTI has once again obtained accreditation for a period of three years from CARF International. This accreditation decision represents the highest level of accreditation that can be awarded to an organization and shows TTI’s substantial conformance to the CARF standards.


According to CARF, an organization receiving a Three-Year Accreditation has put itself through a rigorous peer review process. It has demonstrated to a team of surveyors during an on-site visit its commitment to offering programs and services that are measurable, accountable and of the highest quality.


The latest accreditation is the eighth consecutive Three-Year Accreditation that CARF has awarded to TTI.
