Evidence worth noticing

Strengths and momentum

No academic result met this site’s published threshold for a selected positive signal against Similar economic-disadvantage rate.

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 charter school system.

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 Not Rated with 69 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.

Academic Growth55F5
Relative Performance50F10

Closest to moving up: Student Achievement, 3 points below D 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 charter school system that better measure is Student Achievement (57), so School Progress (55) is published above but does not enter the overall score at all — gaining points there changes nothing until it passes 57.

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 charter school systems 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 charter school systems for which TEA reported that measure; metric-specific reporting counts are shown on the STAAR, graduation and CCMR rows and may vary.

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.

Enrollment over time

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

TEA reported 132 students in 2025–26, a decrease of 7 (5.0%) from 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.

TEA does not publish a transfers-out total or a resident population for this charter system. A charter system is not a geographic attendance boundary, so a net transfer balance cannot be calculated and this page does not label the system a transfer gainer or loser.

Selected comparison figures are average reported transfer-in counts among charter systems, not rates; system size affects them. They provide scale context and are not a performance judgment. This charter system’s official total does not change when the comparison does.

Source: TEA Student Transfer Reports, fetched 24 August 2026. The total and origin rows are TEA’s published charter-system figures; this site does not add masked detail cells. A transfer-in count does not say why a family chose the charter or whether one school is better.

Discipline and removal from class

Selected comparisons use rates, not raw counts, so differently sized charter school systems can be read on the same basis. Each average uses only group members for which TEA reported that rate; this charter school system'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.

TEA defines this charter school system rate as the share of teacher full-time equivalents from the prior fall who are not employed as teachers in the charter school system in the current fall. That can include leaving the charter school system or remaining in a different role; it is not a campus-level measure. The comparison average changes with the selected group; this charter school system's reported rate does not.

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.
