Summary:
The two public schools in zip code 78588 serve the rural community of San Isidro, Texas, and are part of the San Isidro Independent School District (Isd), a small district with about 153 students across San Isidro Elementary (serving pre-kindergarten through 8th grade) and San Isidro High School (serving 9th through 12th grade).
San Isidro High School stands out as the district's academic bright spot, achieving a 100% graduation rate and a 0% dropout rate despite serving a 100% economically disadvantaged student body. The high school has shown strong performance in English, with a 100% proficiency rate on the English II Reading EOC exam in the most recent school year, far exceeding the state average. In contrast, San Isidro Elementary faces significant challenges, particularly in mathematics, where multiple grade levels recorded 0% proficiency in recent years. However, the elementary school does have a notable bright spot: its 7th grade class achieved a 100% proficiency rate in Reading, and the school benefits from a very low student-teacher ratio of 8.6 to 1, allowing for personalized attention.
A key takeaway is the stark disparity between reading and math performance across the district. While reading scores show moments of excellence, math proficiency remains critically low, with the highest math proficiency rate in the entire district being just 50% in 5th grade. The district spends significantly more per student ($16,000 to $18,000) than the state average, yet this investment has not translated into strong math outcomes, suggesting a need for specialized math curriculum or instructional strategies. The high school's ranking volatility—jumping from the 55th to the 83rd percentile in one year—is typical for small schools, where the performance of a single class can dramatically shift overall metrics.
