Selected positive signals, not a summary of performance. The same rules choose them on every page: only the latest one-year gain, results meaningfully better than the currently selected comparison with broad reporting, and distinctive top-three placements. Demographics, staffing and spending cannot become academic “wins.” The overall rating and the full results below remain the complete picture for this school.

Put the numbers in context
Follow the solid line to see how this school has changed. Turn comparison lines on or off to add context.
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 84 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.

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.
| Domain | Score | Grade | Points to next grade |
|---|---|---|---|
| Student Achievement | 94 | A | — |
| School Progress | 96 | A | — |
| Closing the Gaps | 90 | A | — |
| Academic Growth | 70 | C | 10 |
| Relative Performance | 96 | A | — |
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 (96), so Student Achievement (94) is published above but does not enter the overall score at all — gaining points there changes nothing until it passes 96.
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.
These measures use TEA's standard-accountability population. Each comparison average includes only schools in that population that report that specific measure; its reporting count is shown beside the average. It is an unweighted average of those reported school rates, not a pooled rate across every student in the group.

Every row is a share of this school's graduates, and every row is a way of meeting CCMR — so on every row, a bigger share is better. Difference is this school minus the average for schools with a similar economic-disadvantage rate, counted in percentage points: +5.0 would mean five more graduates in every hundred met that criterion here. The selected comparison is an unweighted average of the reported school percentages, not a pooled rate across all graduates in the group. Graduates may meet several criteria, so the rows do not add up to the total.
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.

Selected comparison counts are neutral cohort scale context. The percentages put differently sized graduating classes on the same basis, but still cover only the limited Texas-public system observed by this report.
Source: Texas Higher Education Coordinating Board, high-school graduates enrolled in higher education, fetched 24 August 2026. The report covers graduates who enrolled in a Texas public college or university the following fall and includes only districts or campuses with more than 25 graduates.
“Not found” does not mean a graduate did not continue their education. It can include private or out-of-state college, work, military service, enrollment after the fall term, or another path the Texas public system does not observe.
“Not trackable” is not an outcome. THECB uses it for graduates with a non-standard identifier that could not be matched to higher-education records.
Placed after the results deliberately: this is context for reading them, not an explanation of them.

TEA-published share: 65.7%
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. Small-number and complementary masks, unavailable values, and blank not-reported fields stay separate and are never estimated. TEA masking definitions.
TEA-reported student enrollment for each available school year. Enrollment growth or decline is not a measure of school quality.
TEA did not publish an enrollment count for 2025–26 in this PEIMS report, so no current year-over-year change is calculated. The latest available PEIMS count is 173 students in 2024–25.

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.
The campus and its parent district stay fixed while the selected same-sector txschools.net comparison changes with the page-wide control. TEA's own peer group and statewide reference remain visible as separately published, fixed TEA references.
For 2025, TEA reported $17,062 per student for this campus, $21,252 per student for its parent district, Southwest ISD, $18,972 per student for the Texas average.

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.
