The Arizona Department of Education collects student enrollment data from every school district in the state. Arizona Luminaria built a searchable database of that information so you can look up enrollment trends for schools in Southern Arizona’s largest districts.
School enrollment projections by the Arizona Department of Education for Fiscal Year 2026 are based on average daily membership. That number refers to the average number of students enrolled and attending a school each day during the first 100 days of the school year. It is based on daily enrollment and on the instructional minutes required by law for each grade level, Tucson Unified School District Chief Financial Officer Ricky Hernández said.
The membership includes students who are part-time, online, or who transfer mid-year, which can generate partial numbers, according to the state.
The projected count at Day 100 — usually between the end of January and the beginning of March, depending on the school district — is vital to how the state calculates funding. The average daily membership and corresponding funding is not finalized until summer when the state performs a statewide recalculation for any updates to student data that are made through June 30, Hernandez said.
You can search for schools within the six largest school districts in Pima County: Amphitheater, Marana, Sahuarita, Sunnyside, TUSD and Vail.
Notes: Online schools are included in this data. Some merged or closed, others had enrollment peaks in 2022 and numbers have flattened or declined significantly after the COVID-19 pandemic. Districts report their average daily membership numbers by school each month. The fiscal year began July 1 and ends June 30, 2026.
