Grulla Middle is a school on a clear upward trajectory, with its state ranking jumping from the 27th percentile to the 48th percentile over the last three years.

The school boasts a favorable student-teacher ratio of 10.9:1 and a 0.0% dropout rate, indicating strong student support. Its most exceptional achievement is in advanced math: 100% of Algebra I test-takers were proficient in the 2024-2025 school year, and 90.91% were proficient the following year—far exceeding both the district and state averages.

However, performance is uneven across subjects and grades. While 8th graders outperform their younger peers in reading and math, 7th-grade math proficiency (19.15%) is a significant concern, well below the state average. The school shows relative strength in 8th-grade Social Studies, outperforming the state, but struggles in 8th-grade Science, where only 22.79% of students were proficient compared to the state average of 46.25%. Overall, Grulla Middle is part of the Rio Grande City Grulla Independent School District (Isd) and demonstrates a promising trend of improvement, especially for its top math students, while still facing challenges in core subjects like science and 7th-grade math.
