Rancho Isabella El, Angleton TX - Test Scores & Data

Original Research by School Decision on Rancho Isabella El

Rancho Isabella Elementary sits on Corral Loop in Angleton, the Brazoria County seat, serving children from pre-kindergarten through fifth grade as part of Angleton ISD. The school draws from a community that is growing quickly: new subdivisions are being platted and occupied across the city, a master-planned community called Ashland is rising in north Angleton with its own school campuses, and the city has launched a comprehensive plan to manage growth over the coming decades. That context matters for families thinking about neighborhood stability and school capacity.

The student body is a majority-Hispanic school with a substantial share of White and Black students and a smaller multiracial population. A large majority of students qualify for free or reduced-price lunch, placing the school squarely in a high-need economic context. Data on English learner enrollment and special education rates were not available in what was provided.

On the Texas STAAR, the picture is uneven and worth examining grade by grade. Third grade lands near the middle of the state in both reading and math, with roughly half to slightly more than half of students reaching the proficient bar. Fifth grade is the school's strongest tested year: a majority of fifth graders met or exceeded expectations in reading, and about half did so in math and science. Fourth grade is the soft spot. Reading proficiency in fourth grade was well below the other grades, and math was lower still. That single-grade dip is noticeable, and a parent may want to ask the school directly what is being done to support students through that transition year. Across all tested grades and subjects combined, the school's overall proficiency index places it in the top quartile relative to districts in Brazoria County, which is a meaningful position in a county that includes several large suburban systems. The "approaches grade level" threshold, the lowest bar on STAAR, is met by a large share of students across subjects, suggesting most kids are in the range. Mastery-level performance, the highest bar, is reached by a smaller share, which is common but worth naming.

Multi-year trend data was not available; only a single year of results appears in the data, so there is no way from what was provided to say whether performance is climbing, flat, or declining. Program details for the school were not included, so specifics about tutoring, enrichment, bilingual offerings, or intervention supports are not described here.

Angleton itself is a car-dependent small city, publicly reported as minimally walkable, with no public bus transit. The downtown preserves early-twentieth-century commercial architecture, and the Brazoria County Library and historical museum anchor civic life. Employers range from the school district and county government to a regional hospital campus and, further out, industrial employers tied to energy and manufacturing near Freeport. Housing here is priced well below both the Texas median and the national median, and monthly carrying costs remain more accessible than in much of the Houston metro. Rents run meaningfully lower than a comparable mortgage payment, which makes renting a financially viable path in this market.

No parent-relevant district changes were confirmed through research, so that piece of context was left out rather than guessed at.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
