DPS Crime Lab Accreditation Program

The DPS Crime Lab Accreditation Program was created on September 1, 2003, in Government Code §411.0205. A laboratory or other entity (public or private) conducting forensic analysis of physical evidence must be accredited by DPS in order for that laboratory's evidence or testimony to be admissible in a criminal proceeding.  A laboratory may apply to the Director for statutory DPS accreditation if accreditation is required for evidence admissibility under Code of Criminal Procedure Article 38.35. Accreditation is part of a laboratory's quality assurance program, which should also include proficiency testing, continuing education, customer liaison, and other programs to help the laboratory provide more effective overall service.

In order for a laboratory or other entity to receive full DPS accreditation, the laboratory must first be accredited by a recognized accrediting body.  However, under certain circumstances, provisional DPS accreditation is available for a limited term. The normal term for DPS accreditation begins on the date of issuance of the initial DPS accreditation letter and extends until withdrawn by the recognized accrediting body or withdrawn by the Director.
