San Isidro El, San Isidro TX - Test Scores & Data

Original Research by School Decision on San Isidro El

San Isidro Elementary is a small PreK-through-eighth-grade school serving a rural, low-income community in northeastern Starr County. The school operates as part of San Isidro ISD, a district that spans several small unincorporated communities across a wide agricultural area. The locale itself is a census-designated place at the intersection of two farm roads, historically anchored by a Catholic church, a post office, and the consolidated school. The broader community is characterized by dry-land farming and scattered residential settlement, with most families owning their homes.

The school enrolls a small number of students, the vast majority of whom qualify for free or reduced-price meals. Nearly all students are Hispanic, with only a very small share identifying as white. The student body is almost entirely economically disadvantaged by the federal measure. Demographic data on students with disabilities and English learners was not available in the provided information.

On state assessments, the school's performance is uneven and generally weak. In English language arts, a substantial share of students reach the proficient threshold across grades three through eight, with particularly strong results in grade six. However, math proficiency is very low across most grade levels, with only one grade achieving even modest proficiency rates. Science and social studies results are severe: almost no students met proficiency in grade-five science or grade-eight social studies, with only a handful of students reaching proficiency in grade-eight science. The school's overall proficiency index places it below the midpoint among districts in Starr County. A parent may want to discuss with the school specifically what supports are in place for math instruction and what accounts for the disparity between the school's ELA and math outcomes.

San Isidro ISD has recently introduced a new PreK-3 program, offering free early-childhood education for younger families and positioning early learning as a step toward the district's stated early college and career readiness pathways. This is a notable addition for such a small rural district and reflects a commitment to expanding educational access before kindergarten.

The school's enrollment is small, drawn from a community experiencing population decline over recent decades. The surrounding area includes colonias served by the district. While the school is physically situated in a dispersed rural setting with limited walkability or commercial street life, it functions as a genuine civic anchor alongside the historic church and post office. Families living in this area tend to be rooted in farming, oil and gas work, and rural employment, with limited economic diversity visible in the data.

This school is appropriate for families committed to rural community life who are aware that academic performance in core subjects requires close partnership with the school and may benefit from tutoring or outside support, particularly in mathematics.

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.
