Treasure Coast Elementary School in Sebastian

Treasure Coast Elementary is the Indian River County public school for kindergarten through fifth grade at 8955 85th Street in Sebastian, open 9:00 am to 3:40 pm.

The school's own site lists the day as 9:00 am to 3:40 pm, grades K-5 and the main number 772-978-8500, under the line A School of Marine Science, All Grit No Quit (Treasure Coast Elementary). The district's 2026-2027 Parent Guide directory gives the same 8955 85th Street, Sebastian, FL 32958 address, the 978-8500 number and a K-5th span (SDIRC Parent Guide, page 15). The other public schools with Sebastian addresses in that directory are Sebastian Elementary at 400 Sebastian Boulevard, Pelican Island Classical Magnet at 1355 Schumann Drive and Sebastian River High at 9001 Shark Boulevard (SDIRC Parent Guide, page 14), plus Sebastian River Middle at 9400 CR 512, the Wabasso School at 8895 US Hwy 1 and Indian River Virtual School at 8895 US Highway 1 (SDIRC Parent Guide, page 15).

Indian River County Emergency Management describes the location as Highway 510, just east of Sebastian River High School (Indian River County Emergency Management), and the federal school directory files it under the locale Rural, Fringe (NCES).

The 9:00 start matters for Sebastian families with an older child at Sebastian River High next door, whose day runs 7:20 am to 2:07 pm (Sebastian River High School): the high school student is out more than an hour before the Treasure Coast Elementary bell rings at 3:40.

Treasure Coast Elementary presents itself as a marine science school, and its home page carries the line A School of Marine Science, All Grit No Quit.

The current school site lists the bell times, grades and that tagline on its home page (Treasure Coast Elementary), and its school story page gives only the 8955 85th Street address and the (772) 978-8500 main number (Treasure Coast Elementary story page). Neither current page lists clubs, after-school programs or the details of the marine science curriculum, so families checking whether a specific program runs in 2026-2027 should call the front office at 772-978-8500 before choosing the school for it.

The state grades file gives one measurable view of the science emphasis: Treasure Coast Elementary scored 76 in science achievement in the 2025-26 school grades, its second highest component after grade 3 reading at 80, and above its 70 in English Language Arts achievement and 73 in math achievement (FLDOE school grades file).

Treasure Coast Elementary had 679 students and 42 full-time-equivalent classroom teachers in 2024-2025, according to NCES.

The federal Common Core of Data puts the 85th Street school at 679 students, 42.00 classroom teachers and a student/teacher ratio of 16.17 for 2024-2025, with 347 boys and 332 girls (NCES). That is nearly twice the 354 students the same directory counted at Pelican Island Classical Magnet on Schumann Drive that year (NCES). NCES counted 346 Treasure Coast Elementary students eligible for free or reduced-price lunch.

The Treasure Coast Elementary kindergarten count of 89 is the smallest class in the building, 44 students fewer than grade 3, so the incoming classes at the 85th Street school were smaller than the ones moving through it in 2024-2025.

Treasure Coast Elementary earned an A in Florida's 2025-26 school grades, with 67 percent of possible points, its fourth straight A since the 2023 baseline year.

The Florida Department of Education file dated September 1, 2026 lists Treasure Coast Elementary with 537 points, 67 percent of total possible points and 98 percent of students tested (FLDOE school grades file). The elementary A line in that file is 62 percent. The Sebastian school's components were 80 in grade 3 English Language Arts, 70 in ELA achievement, 64 in ELA learning gains, 51 in ELA gains of the lowest 25 percent, 73 in math achievement, 70 in math gains, 53 in math gains of the lowest 25 percent and 76 in science.

The grade 3 reading score of 80 is the strongest Treasure Coast Elementary number, while the gains of the lowest-scoring quarter, 51 in reading and 53 in math, are the weakest. The file lists the school as Title I, with 59.5 percent of students economically disadvantaged (FLDOE school grades file). The grade history on file begins in 2007, the earliest grade the state lists for the 85th Street school.

Indian River County Emergency Management designates Treasure Coast Elementary at 8955 85th Street, Sebastian, as the county's Special Needs Shelter for residents who need medical assistance during an evacuation.

The county shelter sheet says the Special Needs Shelter is located at Treasure Coast Elementary School on Highway 510, just east of Sebastian River High School (Indian River County Emergency Management). When activated, it is operated by the Fire Rescue Division, the Indian River County School District and the county Health Department, and preregistration is required for the Special Needs Shelter and for transportation to a general population or pet friendly shelter (Indian River County).

Registration is online through the Florida Department of Health, and Indian River County residents without a computer can call 772-226-3900 to request a paper copy (Indian River County). The county sheet adds the practical limits: cots are provided to preregistered special needs clients but caregivers must bring their own cot or sleeping gear, pets are not allowed in the Special Needs Shelter, and anyone needing a ride must register before hurricane season because there are no guaranteed pickups after an evacuation order (Indian River County Emergency Management).

Treasure Coast Elementary is only for residents who meet the medical criteria. Indian River County general population shelters take anyone who is self-sufficient, and people with decreased mobility but no additional medical problems are provided for in a regular shelter rather than at 85th Street (Indian River County Emergency Management). The county also warns that not all shelters open at the same time and some may not open at all, and that pets are allowed only at designated pet-friendly shelters, so a Sebastian household with a pet and a medically fragile member needs two plans.

Treasure Coast Elementary is a zoned neighborhood school, so enrollment starts with the district BusPlanner address lookup and the Focus Parent Portal, with Extended Day care before and after school.

The district's BusPlanner Web site offers a Which School do I Attend? search for the 2026-2027 school year, and states that where there is any discrepancy the transportation office has the final word (SDIRC BusPlanner). Families outside the Treasure Coast Elementary zone can apply through the School Choice application, open each year from November 1 to the end of June (SDIRC Parent Guide, page 23).

The district Extended Day Program runs at Treasure Coast Elementary on regular school days for kindergarten through fifth grade. The 2026-2027 Parent Guide sets the K-5 hours at 7:00 to 8:30 a.m. and 3:40 to 6:00 p.m., with the fees below; a late pickup costs $10.00 per child for every 15 minutes past 6:00pm, and the office number is 772-564-4999 (SDIRC Parent Guide, page 45).
