Summary:
There are three elementary schools in zip code 79849, serving grades PK-6 in the San Elizario area of Texas, all part of the San Elizario Independent School District (Isd).
For parents, the standout school is L G Alarcon Elementary, which is the smallest school with the lowest student-teacher ratio (16.5:1) and the highest per-student spending ($11,704). It consistently posts the highest test scores in the area, including the best 3rd Grade Reading (43.86%) and 3rd Grade Math (35.94%) proficiency rates. In contrast, Josefa L Sambrano Elementary is the largest school with the highest student-teacher ratio (21.5:1) and lowest spending ($10,457), but it shows the most improvement, jumping from the 10th percentile to the 44th percentile between 2017 and 2019. Alfonso Borrego Senior Elementary has a unique strength in 6th Grade Math, where it achieved a 49.12% proficiency rate in 2024-2025, outperforming the state average of 37.68%.
All three schools serve a student population that is over 87% economically disadvantaged, and overall academic performance is well below state averages in both Reading and Math. A clear pattern emerges: smaller schools with more resources per student tend to perform better, as seen with L G Alarcon. The district as a whole faces significant challenges, but the data suggests that targeted instruction, particularly in math for English Language Learners, and smaller class sizes could be key to improving outcomes for students in this area.
