P20 WIN was established to inform sound policies and practice through the secure sharing of longitudinal data across participating agencies to ensure that individuals successfully navigate supportive services and educational pathways into the workforce.
Connecticut created P20 WIN in 2014 and codified in Connecticut General Statutes 10a-57g. The SLDS is as a federated longitudinal data system, which means data is not housed centrally in state government. A comprehensive data request process has been created in order to facilitate data requests for internal agency analysis, academic and other researchers, and policy-makers. The P20 WIN Learning Agenda reflects the priority issues of the state and state agencies.
In July 2025, P20 WIN was re-branded as DataLinkCT to better communicate its role in facilitating the sharing and linking of data for approved data requests.
