Summary

San Isidro Elementary is a high-performing PK-5 school in Laredo, TX, serving 794 students within the United Independent School District (Isd), and it has earned a 5-star rating from SchoolDigger for five of the last six years, consistently ranking in the 94th to 96th percentile statewide.

What truly sets San Isidro apart is its exceptional ability to drive success for all students, particularly those from low-income backgrounds. The school ranks in the 99th percentile statewide for its effectiveness with both Hispanic students and low socio-economic status (SES) students, a rare achievement that shows it closes achievement gaps rather than just serving a more affluent population. While nearby schools like Kazen Elementary (95th percentile) and Col Santos Benavides Elementary (91st percentile) are also strong, San Isidro’s sustained performance in the 96th percentile over the past three years is unmatched. In contrast, other nearby schools like Barbara Fasken Elementary (68th percentile) and Finley Elementary (25th percentile) perform significantly lower. The school’s test scores are consistently 20-30 percentage points higher than the district average and 25-35 points higher than the state average across all subjects and grade levels.

San Isidro’s success is built on a foundation of consistent excellence over time, with only a brief dip during the pandemic year (2020-2021) before quickly rebounding to the top 5% of Texas elementary schools. The school serves a student population with a lower poverty rate (about 36% free/reduced lunch) compared to neighbors like Nye Elementary (76.79%) and Roberto J Santos Elementary (58th percentile), but its ability to rank in the 99th percentile for low-SES students proves it is not just a "good school for wealthy kids." One area for potential growth is 5th Grade Science, where proficiency rates (50.97% in 2024-2025) are still above district and state averages but lower than the school’s stellar reading and math scores. Overall, San Isidro stands out as a model of educational equity and effectiveness in Laredo.
