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, the National Education Association (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 2019--provides state-level data on an array of topics relevant to the complex enterprise of public education. Since the 1960s, Rankings has presented facts and figures useful in determining how states differ from one another--and from national averages--on important school statistics such as student attendance, teacher employment and average salary, and school revenues and expenditures. Of course, no set of tables tells the entire story of a state's education offerings. Consideration of factors such as a state's tax system, provisions for other public services, and population characteristics also are needed. Therefore, it is unwise to draw conclusions based solely on individual statistics in this report. Part II of this report--Estimates 2020--is in its 75th year of production. Estimates provides data tables projecting public school enrollment, employment and compensation of personnel, and finances, as reported by individual state departments of education. Not surprisingly, interest in the improvement and renewal of public education continues to capture the attention of the nation. Part III of this report--National Trends 2011-20--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. Such trends at the national level have been based on data reported state by state. [For "Rankings of the States 2018 and Estimates of School Statistics 2019," see ED600923.]
