Summary:
Lake Dallas Independent School District (Isd) is served by a single high school, Lake Dallas High School, which educates 1,283 students in grades 9-12 in Corinth, Texas, and has shown a strong upward trajectory in state rankings over the past three years.
Lake Dallas High School stands out for its near-perfect graduation rate of 99.7% and a very low dropout rate of 0.2%, both significantly better than district averages. The school consistently outperforms the state in core subjects like U.S. History (77.92% proficient vs. 70.17% state) and Biology (73.74% vs. 70.51%), and also excels in English I and II reading. However, a key anomaly is Algebra I, where the school slightly underperforms the state average (52.74% vs. 54.03%). Notably, this Algebra I proficiency rate more than doubled from the previous year (24.91% to 52.74%), a dramatic swing that warrants further investigation into curriculum or testing changes. With a student-teacher ratio of 15.5:1 and per-student spending of $10,639, the school operates with reasonable resources while maintaining a positive trend, improving its state percentile rank from the 63rd to the 69th percentile over three years.
For parents, the key takeaway is that Lake Dallas High School offers a strong, improving educational environment with excellent graduation outcomes and solid performance in humanities and sciences. The main area of concern is math proficiency, which, despite a recent huge improvement, still lags behind state averages. The school’s consistent upward momentum in state rankings and its ability to move nearly all students to graduation suggest effective leadership and a focus on continuous improvement, making it a compelling choice for families in the area.
