Summary

Old Union Elementary in Southlake, TX, is a PK-4 school within the highly acclaimed Carroll Independent School District (Isd), serving 458 students and consistently ranking among the top 100 schools in Texas, including a #1 state ranking in 2018-2019.

While Old Union remains an elite school—ranking 81st out of 4,627 schools in 2025-2026, placing it in the 98th percentile—it operates in an intensely competitive environment. Its closest district peers, Carroll Elementary (#14), Jack D Johnson Elementary (#15), and Robert H Rockenbaugh Elementary (#16), have all surpassed it in recent rankings. A key factor is a dip in math proficiency: in 2025-2026, Old Union's 3rd-grade math proficiency (77%) and 4th-grade math proficiency (79%) fell below the district average (84% and 86%, respectively), a reversal from previous years when it exceeded those averages. However, the school shows strength in reading, with 3rd graders achieving 96% proficiency—the highest in the district—and exceptional performance with Asian students, ranking 20th in the state. Old Union also maintains a favorable student-teacher ratio of 12:1, lower than its main district rivals, suggesting a more personalized learning environment.

The contrast with nearby schools in the Grapevine-Colleyville Independent School District (Isd) is striking. For example, Timberline Elementary, just 1.28 miles away, scored 55% in 3rd-grade reading compared to Old Union's 96%. This disparity highlights the profound impact of school district boundaries on educational outcomes. Despite recent fluctuations, Old Union's strong reading scores and improved subgroup performance suggest it is well-positioned for a return to the top tier of its district.
