State postsecondary education governance systems play an important role in the policy and decisionmaking processes that affect a state's ability to pursue its education and workforce goals. In general, postsecondary education governance relates to the responsibilities and authority of entities and leadership positions charged with developing, implementing and overseeing policies and practices. To assist policymakers and the broader education community in expanding their knowledge of the governance systems in their states and others, Education Commission of the States developed a comprehensive set of resources that include a 50-State Comparison, individual state profiles and a data visualization tool. These resources do not reflect changes that states made in 2019. This Policy Guide summarizes these comprehensive resources to describe postsecondary governance models and structures and examine key components of postsecondary governance systems, and also offers questions for further consideration.
