What this means: About 88% of students here test proficient in math and reading, compared with the roughly 82% typical for Iowa schools with a similar share of low-income students. BeatsExpectations measures results against demographically similar schools rather than by raw scores, and this school falls within the typical range, neither among Iowa's top nor bottom 10%.
BeatsExpectations runs a per-state regression of proficiency on free/reduced-lunch share, then scores each school by residual. How this is calculated →

How to read these scores
What is ISASP?
ISASP is the statewide standardized test administered by Iowa 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 88.0% mean for English Language Arts at Dike Elementary School?
It means about 88.0 percent of students tested at Dike Elementary School performed at grade level or above on the ISASP English Language Arts test in 2024-25. The statewide average for Iowa that year was 73.6%. 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 Iowa, 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?
Iowa Department of Education, Iowa State Assessment of Student Progress (ISASP). School-level data by grade and subject from educate.iowa.gov. Headline metric is the cumulative "Proficient" rate (Proficient + Advanced, top 2 of 3 ISASP levels).
How often is it updated?
ISASP 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.
