This report focuses primarily on the state and local revenues available to support public education, with particular attention paid to the structure of the financing system and changes to it over time. This report also covers the major factors, economic, political, and demographic, that influence performance of state and local revenues. Despite the significant resources being dedicated to K-12 education, there are concerns that the system is somehow “broken” and that schools are “under-funded.” Additionally, concerns about the long-term health of the financing system hinge on projections that spending pressures will outpace revenue growth prospectively.
