How to read these scores
What is AASA?
AASA is the statewide standardized test administered by Arizona public schools.
What does "% Passing" mean?
It is the share of students at the school who performed at grade level or above on the test, summed across the top two of four performance levels. A higher number is better.
What does 35.0% mean for English Language Arts at Tartesso Elementary School?
It means about 35.0 percent of students tested at Tartesso Elementary School performed at grade level or above on the AASA English Language Arts test in 2024-25. The statewide average for Arizona that year was 45.4%. The other students fell into the lower performance levels.
How is the state average calculated?
It is a weighted average, not a simple average of each school's number. We multiply each public school's score by how many of its students tested, add those together for all schools in Arizona, and divide by the total students tested that year. This way a big school with 1,500 students counts more than a small school with 50 students, which is the right way to ask "how did the typical student do this year?". District and county averages on this page use the same method, just scoped to that district or county.
Where does this data come from?
Arizona Department of Education, Arizona's Academic Standards Assessment (AASA) for grades 3-8 and Arizona Science Assessment (AzSCI). School-level All Students subgroup scraped from azreportcards.azed.gov SPA JSON API. Headline metric is the cumulative 'Passing' rate (Proficient + Highly Proficient, top 2 of 4 AASA performance levels).
How often is it updated?
AASA is administered once a year (spring). Results are released by the state in the summer or early fall. We refresh this page after each annual release.
