Summary:
The five elementary schools in the Carroll Independent School District (Isd) in Southlake, Texas, serve grades PK-5 and are part of a district ranked 2nd out of 951 in the state, with all schools placing in the top 2% of Texas elementary schools.
Three schools form a clear top tier: Carroll Elementary (ranked 14th), Jack D Johnson Elementary (15th), and Robert H Rockenbaugh Elementary (16th) are clustered in the top 16 statewide. Carroll Elementary is the standout riser, jumping from 36th to 11th to 14th and achieving a perfect 100th percentile ranking in 2025-2026. Jack D Johnson is a math powerhouse with the highest 3rd and 4th-grade math scores in the district, despite having the lowest spending per student ($9,329). Robert H Rockenbaugh is the consistent performer, ranking in the top 16 for three straight years with the highest spending ($11,813) and the lowest student-teacher ratio (12.1). In contrast, Walnut Grove Elementary (74th) and Old Union Elementary (81st) are still elite but rank roughly 60 places behind their peers, revealing a significant internal performance gap.
Key metrics show enrollment ranges from 458 (Old Union) to 614 (Jack D Johnson), with an average student-teacher ratio of 13.6. A notable paradox is Old Union Elementary, which has the lowest student-teacher ratio (12.0) but the lowest test scores and a steep ranking decline from 20th to 81st, suggesting unique challenges not captured in the data. A district-wide dip in 4th-grade math scores in 2024-2025 was successfully rebounded in 2025-2026, indicating effective intervention. Overall, while all schools perform exceptionally, parents should note the clear performance tiers and the fact that higher spending does not guarantee a higher ranking, as demonstrated by Jack D Johnson's success with the lowest per-pupil expenditure.
