RETAINING ACCREDITATION STATUS To retain accredited status until the assigned expiration date, a forensic service provider is expected to continue to meet the requirements under which it was accredited. The principal means by which ASCLD/LAB monitors conformance are surveillance activities, Performance Declarations, external proficiency testing reports submitted by approved test providers, and forensic service provider self-disclosure of significant events and nonconformities. The results of these monitoring activities will be considered when making a decision on the continuation of accreditation between full assessments. The interval between ASCLD/LAB’s on-site visits to a forensic service provider must not exceed two (2) years.
