What this means: About 78% of students here test proficient in math and reading, well above the roughly 48% typical for Nevada 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 30 points, placing it in Nevada'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 Nevada SBAC?
Nevada SBAC is the statewide standardized test administered by Nevada 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 86.4% mean for English Language Arts at Coral Academy Tamarus?
It means about 86.4 percent of students tested at Coral Academy Tamarus performed at grade level or above on the Nevada SBAC English Language Arts test in 2024-25. The statewide average for Nevada that year was 45.8%. 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 Nevada, 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?
Nevada Department of Education / Nevada Report Card. Smarter Balanced (ELA + Math grades 3-8) and Nevada CRT Science (grades 5, 8). School-level data via the Nevada Report Card public API. Headline metric is the cumulative "% Proficient" rate (Meets + Exceeds Standard, top 2 of 4 SBAC levels).
How often is it updated?
Nevada SBAC 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.
