An analysis of spending in Arizona School Districts is performed annually by the Auditor General's Office in accordance with Proposition 301 (passed by Arizona voters in 2000). This report is typically released in March, but is based on data from the previous fiscal year. These reports are listed under the financial year that they are based on, not the release date. Classroom dollar percentage is the amount spent for classroom purposes divided by the total amount spent for day-to-day operations, or total operational spending.
