Summary

Lake Brantley High School in Altamonte Springs, FL, is a large public school serving 2,813 students in grades 9-12 within the highly-rated Seminole County district. The school boasts an exceptional graduation rate of 97.7%, far exceeding the state average of 92.2% and outperforming nearby Lake Mary High School (95.9%). However, this success is paired with a notable concern: a chronic absenteeism rate of 30.1%, which is the highest among its main Seminole County peers and nearly 5 percentage points above the district average. This paradox suggests the school is highly effective at ensuring students complete graduation requirements, even as a significant portion misses substantial instructional time.

Academically, Lake Brantley shows clear strengths and one major weakness. The school performs strongly in English Language Arts (69% proficient in 10th grade, the highest among nearby schools) and Biology 1 (76% proficient). However, it struggles significantly in Algebra 1, with only 32% of students proficient—a rate less than half the district average (66%) and well below the state average (63%). This persistent math challenge is the school's biggest academic hurdle and a key factor holding it back from a higher state ranking. In contrast, the school is a top-tier option compared to schools in the neighboring Orange County district, significantly outperforming schools like Wekiva High and Maynard Evans High in nearly every metric.

Lake Brantley achieves these results with the lowest per-student spending ($8,088) among comparable area high schools, including Lyman High School ($9,926) and Lake Mary ($9,078). This efficiency, combined with a higher student-teacher ratio (22.9:1), raises the question of whether targeted investment in math intervention programs could solve the Algebra 1 problem and elevate the school to a 4-star rating. For families, Lake Brantley offers a strong overall education with excellent graduation support, but the math weakness and high absenteeism are important factors to consider.
