The data presented in this report provide facts about the extent to which local, state, and national governments commit resources to public education. As one might expect in a nation as diverse as the United States--with respect to economics, geography, and politics--the level of commitment to education varies on a state-by-state basis. Thus, NEA Research offers this report to its state and local affiliates as well as to researchers, policy makers, and the public as a tool to examine public education programs and services. Part I of this report--Rankings 2017--provides state-level data on an array of topics relevant to the complex enterprise of public education. Part II of this report--Estimates 2018--is in its 73rd year of production. Part III of this report--National Trends 2009--18--presents summary data of national trends in student enrollment and attendance, staff salaries, sources of school funding, and levels of educational expenditures in the previous ten years. A glossary is included. [For "Rankings & Estimates: Rankings of the States 2016 and Estimates of School Statistics 2017", see ED581040.]
