School attendance zones in Sebastian, Florida

The zoned public schools for Sebastian addresses are Treasure Coast Elementary or Sebastian Elementary, then Sebastian River Middle and Sebastian River High.

A Sebastian address is matched to one neighborhood school at each level by the School District of Indian River County. On the north county side those zoned schools are Treasure Coast Elementary and Sebastian Elementary for the early grades, Sebastian River Middle for grades 6 through 8, and Sebastian River High for grades 9 through 12. The consolidation plan adopted in December 2025 sends Sebastian Elementary from its Sebastian Boulevard site to the Sebastian River Middle grounds on County Road 512 for August 2026, but in October 2026 both zoned schools still appeared at separate addresses.

The district's address tool decides the edge cases. Its transportation site, BusPlanner Web, offers a Which School do I Attend? search for the 2026-2027 school year and states that the transportation office has the final word on any discrepancy. That lookup carries extra weight in Sebastian this year, because the 2026 rezoning redrew both the Sebastian Elementary and Sebastian River Middle lines.

Every zoned school for Sebastian, along with Pelican Island Classical Magnet, carries a Sebastian 32958 address in the federal school directory.

Federal directory data pins down each campus. The NCES school record places Sebastian River High at 9001 90th Avenue, serving grades 9 to 12. Sebastian River Middle is listed at 9400 Fellsmere Road, the County Road 512 corridor west of the city, with 775 students across grades 6 to 8 in 2024-2025. Treasure Coast Elementary sits at 8955 85th Street with grades K to 5 and 679 students that year, the largest elementary enrollment on the Sebastian side.

Two more campuses carry Sebastian addresses but work differently. Sebastian Elementary is still recorded at 400 Sebastian Boulevard with grades PK to 5 and 312 students in 2024-2025, figures that predate the planned move. Pelican Island Classical Magnet is at 1355 Schumann Drive and listed with grades KG through 6, reflecting its growth into a K-8 school. The Wabasso School on U.S. 1 is classed as a special education school rather than a zoned neighborhood school.

For 2026-2027 the adopted plan redrew the Sebastian Elementary and Sebastian River Middle zones and called for Sebastian Elementary to move onto the middle school campus.

Sebastian's first broad boundary change since 2011 arrived with the 2026-2027 school year. Treasure Coast Newspapers reported in October 2025 that boundaries had for the most part been left alone since 2011, when zones shifted with the opening of Storm Grove Middle School. A month later the district's proposal named the elementary and middle zones to be redrawn: Glendale, Citrus, Sebastian and Dodgertown elementaries, and Gifford, Oslo, Sebastian River and Storm Grove middle schools, along with moving Sebastian Elementary School of the Arts to share the Sebastian River Middle building.

The School Board adopted the plan unanimously. Sebastian Daily reported the 5-0 vote in December 2025, with changes taking effect in August 2026, and said families affected would be contacted about options to remain at their current schools. WQCS dated the vote to Dec. 17, 2025 and tied the plan to a drop of about 2,000 students since 2019.

The Sebastian Elementary site is on the district's possible sale list. In June 2026 Vero News listed the 41.1-acre campus at 400 Sebastian Blvd. among properties the district might sell, noting that its students and faculty would move in with the Sebastian River Middle School campus, leaving the school empty, and gave its assessed value as $4,266,901. The same report said Wabasso School students would move to the Glendale Elementary campus in Vero Beach that summer.

Whether Sebastian Elementary actually relocated is not settled by the official record. By October 2026 the Sebastian Elementary School of the Arts website still printed 400 Sebastian Blvd as its location (school website), and the school calendar placed its October 19, 2026 School Advisory Council meeting at 400 Sebastian Blvd (Sebastian Elementary calendar). The Sebastian River Middle site lists Grades 6-8 and nothing younger (Sebastian River Middle School). A Sebastian Daily back-to-school story dated August 9, 2026 counted the summer relocations, including Glendale Elementary merged into Citrus Elementary, without naming Sebastian Elementary (Sebastian Daily).

Indian River County redrew the lines because its traditional middle schools, Sebastian River Middle among them, were roughly half empty while K-8 and magnet seats had waitlists.

Empty seats drove the vote. Superintendent David Moore told the School Board in October 2025 that district schools stood at about 72 percent of capacity while the K-8 schools, including Pelican Island in Sebastian, were near 128 percent with waitlists, and traditional middle schools used about 57 percent, according to Treasure Coast Newspapers. CBS12 reported a 54 percent enrollment rate across the four middle schools in November 2025, one of which is Sebastian River Middle.

Pairing an elementary and a middle school on the CR 512 site was the Sebastian version of that fix. The same October report quoted Moore saying the numbers did not justify four middle schools, and the November plan also aligned start and dismissal times so elementary and K-8 schools in Indian River County run on one schedule.

Sebastian River High already worked the way the district now wants its other campuses to work. In the October 2025 discussion, Moore noted that Vero Beach High, with its separate Freshman Learning Center, cost about $1.2 million a year more to operate than Sebastian River High, which has all grades 9-12 on the same campus. The consolidation folded the Vero Beach ninth graders back into their main campus, leaving the Sebastian high school zone itself unchanged in shape.

The magnet waitlists were the other pressure. Moore said magnets including Pelican Island and Liberty turned away about 90 students a year, and that about 35 of them ended up in schools outside the district. CBS12 reported the superintendent's assurance that the existing bus fleet would cover the new transportation pattern, a pattern drawn to include routes carrying Sebastian Elementary children to the County Road 512 campus.

Under the 2025 consolidation plan, the Wabasso School program on U.S. 1 in Sebastian was assigned to the Glendale Elementary building in Vero Beach for 2026-2027.

The Wabasso School is not a zoned neighborhood school, but its move is part of the same plan. Vero News reported in June 2026 that the 3.61-acre property at 8895 U.S. 1 in Sebastian, whose main building was built in 1925 and served as the area's first school, later became a center for special needs students ages 5 to 22. Those students were moving to the Glendale Elementary campus in Vero Beach for 2026-2027, and the Wabasso property was among the sites the district asked Cushman and Wakefield to market. WQCS reported that the Glendale building would house the Wabasso school program and a prekindergarten center.

Magnet and charter schools in Sebastian fill seats by application, though Pelican Island kept places for children already zoned there.

Pelican Island shows how a zoned school can become a choice school. When the School Board approved the classical magnet in December 2024, students then zoned to Pelican Island were given first option to remain, while new kindergarten seats follow magnet applications and, if needed, a lottery. The school then held 352 students in a building with room for 654, and new families were reported moving into the Pelican Island attendance zone after the magnet was announced.

Zones still matter for Pelican Island's older students. Its middle grades have no athletics, gym or field, so those Sebastian students play at their zoned neighborhood middle school. Pelican Island, along with Fellsmere Elementary, added sixth grade in August 2025 and was set to add seventh in 2026 and eighth in 2027. Sebastian Charter Junior High on Wave Street is a public charter school that families apply to, outside the zone system.

About 2,227 Sebastian residents were enrolled in grades 1 through 12 in the ACS 2020-2024 estimates, public and private combined.

The U.S. Census Bureau's ACS 2020-2024 5-year release counts 26,262 Sebastian residents with a median age of 58.2, and splits the city's school enrollment into roughly 748 in grades 1 to 4, 731 in grades 5 to 8 and 748 in grades 9 to 12. Sebastian River High alone enrolled 1,777 students in 2024-2025, more than twice the estimated 748 city residents in grades 9 to 12, so its zone draws heavily on unincorporated north Indian River County outside the Sebastian city limits.
