Sebastian River High School: two rating tools, two different reads
Sebastian River High School earns a B on Niche and a 5/10 GreatSchools rating -- ranked #3 among best public high schools in Indian River County -- with 1,791 students at a 23:1 student-teacher ratio. State testing shows 23% of students proficient in math and 45% in reading, alongside a strong 98% graduation rate and an average GPA of 3.47 (SAT average 1150, ACT average 23). As with the Niche-vs-GreatSchools gap common across Florida school ratings, check both tools and visit the school directly before relying on either alone.
Family fit given the city's older demographic
With a median age of 58.2 and 36.8% of residents 65 or older -- the highest senior share of any Treasure Coast market covered in this content stack -- Sebastian's strong district-wide school grades sit alongside a population skewed heavily toward retirees rather than families with school-age children. Movers with kids should weigh the real school quality against a citywide demographic profile oriented toward an older population.
