This report urges states to participate in the State Wage Interchange System (SWIS), as it can aide states in satisfying Workforce Innovation and Opportunity Act (WIOA) reporting requirements, and help states better understand whether former participants in workforce training and education programs are finding good jobs. SWIS is a data sharing tool jointly managed by the Department of Education (ED) and the Department of Labor (DOL) that allows states to exchange anonymized employment and earnings data--wage data, for short--with other states. Compared to earlier wage record exchange systems, SWIS enables states to access individual-level information about more program participants, simplifies the query process for states, and enables states to more efficiently and accurately report the performance of workforce training and education programs. This report discusses the process of data sharing for research and evaluation, SWIS versus Wage Record Interchange System (WRIS) and WRIS 2, data privacy and security provisions, and limitations of SWIS.
