Best Public Schools in Zip Code 77990

Zip code 77990, serving the rural community of Tivoli, Texas, is home to two small public schools—Austwell-Tivoli High School (grades 6-12, 74 students) and Austwell-Tivoli Elementary (grades PK-5, 67 students)—both part of the Austwell-Tivoli Independent School District (Isd), which holds a 3-star rating and ranks in the 53rd percentile statewide.

The standout school in this area is Austwell-Tivoli Elementary, which demonstrates exceptional strength in mathematics. In the 2025-2026 school year, 80% of its 6th graders were proficient in math, far exceeding the state average of 38.57%, and 70% of 5th graders were proficient, also well above the state norm. In contrast, Austwell-Tivoli High School shows a troubling decline, dropping from the 72nd percentile (4 stars) in 2023-2024 to a projected 34th percentile (2 stars) in 2025-2026. The high school also struggles with Algebra I, where only 30.77% of students were proficient versus the state's 54.03%, despite strong elementary math foundations. Both schools benefit from very low student-to-teacher ratios—6.2:1 at the high school and 11:1 at the elementary—and high per-student spending ($22,217 and $17,394, respectively), yet academic performance is inconsistent due to small class sizes where one student's score can dramatically shift results.

Key metrics reveal a mixed picture. The high school has a 76.9% graduation rate but a 0% dropout rate, suggesting students may take longer to graduate rather than leave entirely. The elementary school has a lower percentage of economically disadvantaged students (34.33%) compared to the high school (59.46%). A notable "leaky pipeline" exists: strong elementary math skills do not translate to high school Algebra I success, and subject performance is inconsistent, with the high school excelling in English II Reading (66.67% vs. 59.88% state) and U.S. History (70% vs. 70.17% state) while lagging in English I Reading and Algebra I. This volatility, combined with the high school's declining rank, suggests the district relies heavily on individual teachers or specific student cohorts rather than a systemic, high-quality instructional program across all subjects.
