The vast majority of funds for pre-K through grade 12 public schools in the United States -- nearly $800 billion or over 90% -- come from state and local funding sources. States, not school districts, are obligated to ensure that all students have access to the resources they need to succeed. States can take steps to reduce disparities between districts based on their property wealth. This brief outlines three broad ways that states can allocate state and local revenue more equitably, as well as examples from states that have enacted these policies. The three policy approaches are as follows: (1) Accurately calculating and incorporating measures of local wealth into funding formulas; (2) Allocating additional funding to less wealthy districts; and (3) Exerting state control over property tax policy.
