Lake Dallas Independent School District (Isd)

The Lake Dallas Independent School District (Isd) serves approximately 3,717 students across five schools in the Dallas-Fort Worth area, including one high school, one middle school, and three elementary schools, and is currently ranked in the 55th percentile statewide with a 3-star rating.

Lake Dallas High School is the district's standout performer, boasting a near-perfect 99.7% graduation rate and a 0.2% dropout rate, while outperforming state averages in four of five core subjects (Biology, English I, English II, and U.S. History) and steadily improving its rank from the 63rd to the 69th percentile. In contrast, Lake Dallas Middle faces significant challenges, with its ranking dropping to the 40th percentile and a critical 7th-grade math proficiency rate of just 5.98%, though it excels in advanced Algebra I coursework. Among elementary schools, Shady Shores Elementary is the most consistent, maintaining a 3-star rating and ranking in the 60th-70th percentile with strong 5th-grade reading and math scores, while Corinth Elementary has shown dramatic improvement, jumping from the 36th to the 61st percentile over three years. Lake Dallas Elementary ranks lowest in the district at the 30th percentile with a 1-star rating.

The most striking finding is the "middle school math cliff" at Lake Dallas Middle, where on-grade-level math instruction struggles despite strong advanced math performance, suggesting a need for targeted curriculum support. The high school acts as a powerful "value-add" institution, effectively helping students succeed despite incoming academic gaps. Per-student spending varies from $9,782 at the middle school to $11,220 at Shady Shores Elementary, and student-teacher ratios range from 12.5:1 at Lake Dallas Elementary to 15.5:1 at the high school. For the district to improve its overall standing, focused resources should be directed to Lake Dallas Middle and Lake Dallas Elementary, particularly in mathematics.
