This report provides key insights into the difficult working conditions endured by teachers in Arizona and across the nation. Arizona provides just $8,569 in per pupil funding, the lowest among all states. In fact, Arizona provides $5,477 "less" per pupil than the national average. Arizona also invests only 2.5% of its state wealth, as measured by the gross domestic product of its economy, in K-12 public education -- the lowest percentage in the nation. And Arizona's high-need schools, as measured by district poverty levels, receive the same levels of funding as the state's low-need schools. In this report, the authors present their analysis of the condition of public school funding in Arizona and 48 other states. Using the most recently available data from the 2016-17 school year, they rank and grade each state on three core measures to answer the question: How fair is school funding in your state? The measures are: (1) Funding Level; (2) Funding Distribution; and (3) Funding Effort. Each state's rankings and grades on these school measures are presented as a tool to inform policymakers, business and community leaders, teachers, parents and students about the condition of public school funding in their state. The report is also designed to assist advocates in their efforts to improve the level and distribution of school funding for students in state public school systems.
