Summary

Sebastian River High School is a large public high school in Sebastian, FL, serving 1,777 students in grades 9-12 as part of the high-performing Indian River School District, which ranks in the top 10% of Florida districts.

While the school has a solid 3-star rating and a strong graduation rate of 98.1%—higher than both the district (96.0%) and state (92.2%) averages—it faces a significant challenge with chronic absenteeism. Nearly half of students (47.3%) are chronically absent, which is 1.5 times higher than the district average and far worse than nearby Bayside High School (28.9%) and Indian River Charter High School (18.0%). Academically, the school shows a split: Algebra 1 proficiency is a notable weakness at just 29% (well below the district average of 64%), but students perform at or above state averages in Biology 1 (78%), US History (80%), and English Language Arts (62-66%). The school also spends slightly more per student ($10,415) than its peers, yet outcomes lag behind the charter school, which spends less.

On a positive note, Sebastian River is on an upward trajectory, with its state ranking improving from the 41st percentile in 2021-2022 to the 65th percentile in 2025-2026. Test scores in ELA, Biology, and US History have steadily risen over the past three years, suggesting recent initiatives are making a difference. The high graduation rate despite high absenteeism may indicate effective credit recovery programs, but families should consider the school's math support and attendance culture when evaluating options. For comparison, Vero Beach High School has similar absenteeism (51.7%) and math scores (33%), while Indian River Charter High School offers a starkly different profile with lower absenteeism and higher test scores across the board.
