WICHE’s Multistate Longitudinal Data Exchange (MLDE) facilitates data sharing between states from K-12 education, higher education, and labor agencies. For the past several years, WICHE has retained the Education and Employment Research Center at Rutgers, The State University of New Jersey to conduct an evaluation of the development and deployment of the MLDE. This brief is one of a series written by EERC and examines the process of building trust within the context of the development and implementation of the MLDE.
