How to read these scores

What is ISAT?
ISAT is the statewide standardized test administered by Idaho public schools.
What does "% Proficient" 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 77.6% mean for English Language Arts at PROSPECT ELEMENTARY SCHOOL?
It means about 77.6 percent of students tested at PROSPECT ELEMENTARY SCHOOL performed at grade level or above on the ISAT English Language Arts test in 2024-25. The statewide average for Idaho that year was 53.4%. 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 Idaho, 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?
Idaho Department of Education, Idaho Standards Achievement Test (ISAT — Smarter Balanced for ELA/Math, Idaho Science). School-level All Students subgroup from the Idaho Report Card public DataExport API. Headline metric is the cumulative "Proficient + Advanced" rate (top 2 of 4 ISAT levels: Below Basic / Basic / Proficient / Advanced).
How often is it updated?
ISAT 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.
