Olmito El, Brownsville TX - Test Scores & Data

Original Research by School Decision on Olmito El

Olmito Elementary is a small elementary school serving pre-K through fifth grade in Brownsville, part of Los Fresnos Consolidated Independent School District. The school draws a student body that is overwhelmingly Hispanic, with a substantial share of students qualifying for free or reduced-price meals, reflecting the economic circumstances common to the Rio Grande Valley. Most of its enrollment comes from the neighborhoods immediately surrounding the school along Arroyo Boulevard.

On state assessments, Olmito's students show solid proficiency across tested grades and subjects. In third-grade English language arts, about three-quarters of students scored at proficient or above. Fourth graders in English also reached similar proficiency, while fifth graders in both English and math showed broadly comparable performance, with English proficiency in the higher seventies and math in the mid-seventies. The school's overall proficiency index ranks in the top quartile among districts across Cameron County, a strong position that reflects consistent performance across the grades that are tested.

The school has very limited state assessment data for fourth and fifth grade math, and for science, due to small Spanish-language testing cohorts, so a complete picture of performance in those areas cannot be drawn from the available results. The data that does appear shows the school performing well in foundational English language arts and math at the grades where larger numbers of students take the assessments.

Brownsville itself is a border city in transition. It is experiencing rapid residential growth driven by major economic investments from SpaceX, Texas LNG, and the Port of Brownsville, with housing development accelerating as employers move into the region. The city has been investing heavily in downtown revitalization, walkability, and civic infrastructure, though much of the broader city remains auto-oriented commercial corridors. For families in the Olmito attendance zone, the school fits into a district that has expanded its capacity and programs through recent bond funding. Los Fresnos CISD opened a new middle school in the past couple of years and, as of fall 2025, opened a Career and Technical Education Center and a new Performing Arts Center, giving students access to expanded career training and arts programming. The district has also cut its property tax rate repeatedly, directly reducing the tax burden for homeowners.

Olmito Elementary's teaching environment is characterized by a small, economically diverse student population in a district making visible long-term investments in facilities and programs. For families seeking a neighborhood elementary school with solid foundational academic results and access to growing district-level career and arts pathways, the school offers a clear pathway. Parents may want to look into the school's specific literacy and math support structures for students scoring below proficient, since a quarter to a third of students in each grade fall into that range.

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.
