What Westat does
Westat is a U.S.-based, employee-owned professional research corporation founded in 1963 and headquartered in Bethesda, Maryland, providing statistical survey research, custom research, program evaluation, and technical assistance to U.S. federal agencies and select commercial clients. Its core work spans health services research, clinical research, education, social policy, transportation, public health, food and nutrition, and labor — anchored by long-tenured contracts such as the AHRQ Medical Expenditure Panel Survey Household Component (MEPS-HC, in continuous operation since 1996 and re-awarded in October 2024) and the U.S. Department of Education's IDEA Data Center (since 2013). Westat fields one of the largest in-house multimode survey infrastructures in the federal research market, combining CAPI, CATI, CAVI, web, and paper self-administered questionnaires with proprietary statistical imputation (4,000 class variables for MEPS), NLP-based classification of open-ended responses, AI-driven falsification detection in recorded interviews, and synthetic data generation methods (MACH, SDCPert, DataSwap, sdcnway).
The company's technology backbone is WesLytics™, a trademarked enterprise data intelligence platform that integrates the Databricks AI and cloud management platform with Westat's statistical and methodological expertise for managing, engineering, and analyzing data at population scale, including synthetic data work over 30+ billion rows of real-world patient records. Operations are governed by enterprise-wide Data Governance and AI Governance frameworks aligned with NIST, FCSM, and NAIRR standards, plus an Institutional Review Board for Human Subjects Protections and Common Rule-compliant research practices. Complementary capabilities include biostatistics and epidemiology, biomedical informatics and data coordination (e.g., REDS-IV-P), biostatistics support for clinical trials, and policy evaluation for CMS Innovation Center models such as EOM and AHEAD.
Westat's business model is contract-driven and proposal-based, with revenue primarily derived from multi-year U.S. federal prime contracts and subcontracts (e.g., teaming with the Lewin Group for CMS work); pricing is not publicly disclosed and is set through federal procurement vehicles rather than list prices. Customer segments are led by HHS operating divisions (CMS, AHRQ, NIH, NCI, CDC), the U.S. Department of Education, the U.S. Census Bureau, USDA, and state agencies such as Nebraska DHHS, with a smaller commercial clinical research line. Distribution combines direct federal enterprise sales, subcontractor and teaming partnerships, and a self-serve research-participant portal; demand generation is reinforced by active participation in industry conferences (AAPOR, ASA, AERA, APPAM, FedCASIC, WSS, SAE) and a content marketing program (Insights, podcasts, webinars, newsletters).
