Summary:
The city of Southlake, Texas, is served by 12 schools spanning grades PK-12, with the vast majority belonging to the nationally recognized Carroll Independent School District (Isd), which is ranked 2nd in Texas, and one school from the Keller Independent School District (Isd).
For parents, the standout feature of Southlake schools is the exceptional and consistent performance across the entire Carroll Independent School District (Isd). Every Carroll ISD school ranks in the 98th percentile or higher statewide. The top performers are Robert H Rockenbaugh Elementary (ranked 9th in Texas) and Carroll Elementary (ranked 11th), both of which boast math proficiency rates exceeding 98% in some grades. The district's middle schools, such as Carroll Middle and George Dawson Middle, show remarkable math acceleration, with Algebra I proficiency rates over 97%. The high school system is uniquely structured: Carroll High School serves grades 9-10 as an alternative school, while Carroll Senior High School serves grades 11-12 and achieves a 99.3% graduation rate with a 0.0% dropout rate. The only non-Carroll school, Florence Elementary (Keller ISD), is still strong, ranking in the 89th percentile, and is the only school in the city reporting a free/reduced lunch percentage.
A key takeaway is the district's culture of academic excellence, reflected in its low student-teacher ratios (averaging 15.1:1) and high per-student spending (averaging $10,078). However, parents should note a significant anomaly: Carroll Senior High School reported an 11.11% proficiency rate in English II Reading for 2025-2026, a drastic outlier compared to the district's 89.57% average. This single data point warrants further investigation, as it contradicts the school's otherwise stellar record. Overall, Southlake offers a top-tier educational environment with a clear emphasis on math and science achievement, though the English II score discrepancy is a critical detail for families to explore.
