Data Quality Certification


We conduct data quality assurance and data profiling services to ensure decision support data are complete and accurate. We also independently verify and validate system requirements and data.

Our work includes certifying that systems, data, deliverables, and other products developed by a third party meet a client's requirements. We directly evaluate these products and review system-generated reports to make recommendations for our clients, who can use this information to make a final determination. Our quality standards and thorough quality assurance reviews ensure effective certification plans and processes and give clients confidence in the results.

Featured Work:
  • Data Requirements Testing and Integration Engineering for Federal Health Insurance Exchanges. Mathematica developed tools for the new health insurance exchanges created by the Affordable Care Act that generate test data for all federal and state partners for different types of system testing and calculate the expected results for these data. Mathematica’s partners on this project include state Medicaid and Children’s Health Insurance Programs (CHIP), the Social Security Administration, the Internal Revenue Service, the U.S. Department of Homeland Security, Medicare, and other federal and state agencies. We are also analyzing and recommending improvements to the testing process. 

  • Assessment of Nutrition Assistance Program Administration in the Commonwealth of Northern Mariana Islands. The recent Farm Bill required the Food and Nutrition Service to determine what changes must be made to the Commonwealth's Nutrition Assistance Plan so that it conforms to the requirements of the Supplemental Nutrition Assistance Program used in the 48 contiguous states. We are analyzing the Commonwealth's employment and training programs to determine what changes must be made to conform to the Supplemental Nutrition and Assistance Program and to estimate administrative costs. 

  • Providing Business Analytics and Data Quality Development for Medicaid and CHIP Business Information Solutions (MACBIS)Medicaid and CHIP are the largest sources of health coverage in the United States and are growing in size and complexity. The Centers for Medicare & Medicaid Services is partnering with states to support innovations that will slow growth in program costs and increase the quality of care provided by these programs. The team focuses on developing a program and tools for advanced data quality detection and dissemination as well as designing and developing reports and other analytic products.  

  • Helping State Unemployment Insurance Agencies Improve Data QualityMany states have interpreted federal requirements for Unemployment Insurance data collection and reporting in different ways, leading to confusion among states about what data they should report. Mathematica has worked with numerous state unemployment agencies to independently verify and validate their data validation systems. By helping to improve Unemployment Insurance data quality and generate more reliable and accurate reports, Mathematica’s work improves programs that provide benefits to assist millions of Americans dealing with job loss.

  • National Medicaid Statistical Information System. Mathematica is the Center for Medicaid and CHIP Services’ lead data quality assessor for Medicaid Statistical Information System and Transformed Medicaid Statistical Information System operational readiness testing files. In this role, Mathematica detects anomalies in the databases submitted by all state Medicaid agencies and advises states attempting to resolve the critical anomalies. This project is a continuation of work that Mathematica has been carrying out for the Centers for Medicare & Medicaid Services since 1998.

  • TANF Technical Assistance.  Mathematica has performed four tasks for the District of Columbia, Department of Human Services, Income Maintenance Administration’s TANF program: (1) developing report specifications for the TANF Performance System; (2) providing technical assistance to the Income Maintenance Administration and to its software vendor on the functionality of the TANF Performance System; (3) testing all updates to the system to ensure that they conform to the specifications; and (4) providing data and policy analysis to support the District’s TANF program.
