Summary

Petronila Elementary in Robstown, TX, is a small, rural school serving 110 students in grades PK through 5, and it is part of the high-performing Bishop Consolidated Independent School District. This school is an academic powerhouse, ranking in the 97th percentile statewide (131 out of 4,627 schools) and earning a 5-star rating, with a history of excellence in 6 of the last 10 years. Despite 67% of students being eligible for free or reduced lunch, the school achieves results that far exceed expectations, ranking in the 99th percentile for serving low socio-economic status students—a stark contrast to nearby schools like Los Encinos Ses (47th percentile) and Driscoll Elementary & Middle (35th percentile), which have similar or higher poverty rates.

Petronila’s STAAR test scores are consistently 20-40 percentage points higher than the state average and local peers. For example, 4th-grade math achieved 100% proficiency, double the state average (49.28%) and far exceeding Bishop Elementary (84.81%) and Robert Driscoll Junior Stem Academy (27.72%). Similarly, 5th-grade reading scored 95% proficiency, compared to the state average of 58.47% and Bishop Elementary’s 62.07%. The school also excels with specific subgroups, ranking in the 99th percentile for male students and the 98th percentile for Hispanic students, a key differentiator from many schools in the region.

With a student-teacher ratio of 14.4:1, Petronila offers a personalized learning environment that supports targeted interventions and strong relationships. Its spending of $13,733 per student yields an exceptional return on investment, especially compared to Driscoll Elementary & Middle, which spends more ($14,643) but ranks much lower. The school’s rank history shows a remarkable turnaround after a dip during COVID-19, jumping from the 83rd percentile in 2021-2022 to the 97th percentile in 2025-2026. In a region where many schools struggle—like those in Robstown Independent School District (Isd), which rank in the bottom 13%—Petronila proves that high poverty does not have to mean low performance, serving as a beacon of excellence in rural education.
