What this means: About 18% of students here test proficient in math and reading, below the roughly 34% typical for Texas schools with a similar share of low-income students. BeatsExpectations compares each school with others at the same poverty level, not by raw scores, so a school lands here when its results trail those comparable schools, which is not the same as having low scores. A higher-scoring school can still fall in this tier if similar schools score higher still.
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 STAAR?
STAAR (the State of Texas Assessments of Academic Readiness) is the annual statewide test used by all Texas public schools. Students in grades 3 through 8 take it in reading and math, with science added in grades 5 and 8 and social studies in grade 8. High school students take End-of-Course (EOC) STAAR exams in Algebra I, English I, English II, Biology, and U.S. History.
What does "% Meets Grade Level or Above" mean?
It is the percentage of students at the school whose scores reached or exceeded the "Meets Grade Level" threshold on the test. Texas reports four performance levels (Did Not Meet, Approaches, Meets, Masters). "Meets" and above means the student is performing at grade level or above. A higher number is better.
What does 28.0% mean for Reading at CHARLES GRAEBNER EL?
It means about 28.0 percent of students tested at CHARLES GRAEBNER EL performed at grade level or above on the STAAR Reading test in 2025-26. The statewide average for Texas that year was 54.5%. 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 Texas, 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?
Texas Education Agency, State of Texas Assessments of Academic Readiness (STAAR), via the Texas Academic Performance Report (TAPR). School-level All Students subgroup. Headline metric is the cumulative "Meets Grade Level or Above" rate.
How often is it updated?
STAAR 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.
