Data governance provides state agencies a structure in which to define the roles and responsibilities needed to ensure clear processes for collecting and reporting education data and to ensure accountability for data quality and security. To make informed policy decisions across agencies, such as the state education agency and early childhood, higher education, and workforce agencies, cross-agency data governance is needed. This roadmap provides recommendations for states who are looking to develop and implement a high-quality cross-agency data governance committee. To learn about three leading states and how they approached developing their data governance, see "The Art of the Possible: Cross-Agency Data Governance Lessons Learned from Kentucky, Maryland, and Washington" (ED607233).
