What this means: About 60% of students here test proficient in math and reading, well above the roughly 44% typical for Arkansas schools with a similar share of low-income students. BeatsExpectations ranks schools against others at the same poverty level, not by raw scores, so a school can post high scores and still fall short of its prediction, or post lower scores and still beat it. This school clears its prediction by about 17 points, placing it in Arkansas's top 10%.
BeatsExpectations runs a per-state regression of proficiency on free/reduced-lunch share, then scores each school by residual.
How this is calculated →What is ATLAS?
ATLAS is the statewide standardized test administered by Arkansas public schools.
What does "% Proficient (Level 3+4)" 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 55.7% mean for English Language Arts at GREENBRIER WESTSIDE ELEMENTARY?
It means about 55.7 percent of students tested at GREENBRIER WESTSIDE ELEMENTARY performed at grade level or above on the ATLAS English Language Arts test in 2023-24. The statewide average for Arkansas that year was 33.9%. 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 Arkansas, 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?
Arkansas Department of Education, Arkansas Teaching, Learning & Assessment System (ATLAS). School-level Post-Appeals summary from the ADE DESE assessment files. Headline metric is the cumulative Level 3 + Level 4 rate (top 2 of 4 ATLAS performance levels).
How often is it updated?
ATLAS 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.
