Compare against
2021-22 is shown under the refreshed methodology TEA adopted in 2023, so it is comparable with later years. Under the original scoring it was rated B with 86 that year.
Comparison lines follow the current rated cohort backward through time. The table gives the number in that fixed cohort that reported a score each year; it can be smaller than cohort membership.

Where the score comes from
Texas builds the overall rating from the better of Student Achievement and School Progress, weighted 70%, plus Closing the Gaps at 30%. School Progress is itself the better of Academic Growth and Relative Performance. The 60, 70, 80 and 90 rules mark the letter-grade thresholds.

Closest to moving up: School Progress, 1 point below A in that domain — the nearest of the measures that count toward the overall rating.
TEA does not add the domains up. The overall score is the better of Student Achievement and School Progress at 70%, plus Closing the Gaps at 30%. For this school that better measure is School Progress (89), so Student Achievement (85) is published above but does not enter the overall score at all — gaining points there changes nothing until it passes 89.
Student outcomes
STAAR performance
- Approaches grade level
- Meets grade level
- Masters grade level
- Tick: Similar economic-disadvantage rate (1,112 in cohort)
Percentage of tests at or above each level. Masters is a subset of Meets, which is a subset of Approaches. The selected-comparison tick on each bar marks the average for schools with a similar economic-disadvantage rate — a comparison TEA does not publish.
Counts in the comparison controls describe full cohort membership, not the denominator of every average. Each average uses only schools for which TEA reported that measure; metric-specific reporting counts are shown on the STAAR, graduation and CCMR rows and may vary.

The mobility count and rate use TEA’s separate 2024–25 campus denominator shown above, not current enrollment. This site does not recalculate a missing rate.
The first figure is TEA’s student count for this accountability summary. It is a separate publication from the fall PEIMS enrollment shown above and can differ; this site does not substitute one for the other. Counts come from TEA’s 2025-26 accountability summary, fetched 29 August 2026. A reported zero is shown as 0.

TEA-reported student enrollment for each available school year. Enrollment growth or decline is not a measure of school quality.

The selected comparison column is the average enrollment among reporting schools in that group. It changes with the comparison control; this school's own counts do not.
Source: TEA PEIMS Student Program and Special Populations Reports, fetched 24 August 2026. TEA reports these counts from its fall student snapshot; changes compare adjacent reported school years.
These counts show how enrollment changed, not why. Attendance-zone changes, school openings or closures, grade reconfigurations, transfers and population shifts can affect the total.

Selected comparisons use rates, not raw counts, so differently sized schools can be read on the same basis. Each average uses only group members for which TEA reported that rate; this school's own counts and rates remain fixed.
Students, actions and incidents are different units. One student can receive multiple actions. The categories overlap, so they must not be added together. Rates use TEA's matching cumulative year-end enrollment, not the October enrollment shown elsewhere on this page.
Source: TEA Discipline Reports, fetched 24 August 2026. Suppressed values stay unavailable rather than being estimated. Use 2020–21 cautiously because remote instruction during the pandemic changed students' exposure to in-person discipline. TEA consolidated its separate action-group reports into this product in 2024–25; this trend uses only the stable “All discipline” heading.

Where this comes from
The Texas Education Agency publishes the underlying accountability reports and data downloads. Ratings, outcomes, demographics, staffing and finance on this page come from TEA data available through txschools.gov, fetched 15 August 2026. TEA’s Reports and Data Portal links the official bulk files. Enrollment history comes from TEA's PEIMS Student Program and Special Populations reports, fetched 24 August 2026. The student-count context comes from TEA’s bulk accountability summary, fetched 29 August 2026; TEA’s masking definitions explain withheld values. The dated notice, staffing, discipline, transfer, community and postsecondary sections cite their separate TEA, Census or THECB publication in place. Every archived source carries checksums so each number stays traceable to the bytes the public agency served.
