The District of Columbia Department on Disability Services (DDS) releases a revised Provider Certification Review (PCR) Guide, effective December 21, 2018. This replaces all earlier versions of this guide. DDS, DDA, providers, and other internal and external stakeholders are committed to ensuring that individuals served are healthy, safe and receive services and supports that meet their needs and preferences. Through DDS Quality Assurance and Performance Management Administration, information is gathered from a number of sources in order to set benchmarks for improvement including, but not limited to: incident reports, service coordination monitoring reports, Department of Health/Health Regulation and Licensing Administration (HRLA) licensing reports and DDA Provider Certification Reviews (PCR).
