Summary:

The River Islands Technology Academy II District has one listed school, River Islands Technology Academy II, serving kindergarten through grade 8, with 954 students. In 2025–26, the school’s all-grades proficiency was above the state result in ELA (61% versus 49%), math (51% versus 38%) and science (41% versus 36%). The key finding for parents is that those above-state overall results hide a substantial difference in math performance by grade: grade 6 was below the state, while grade 8 was far above it.

There are no other listed schools to compare, so the strongest and weakest results are within this school. Grade 8 math stands out positively: 65% proficient compared with 36% statewide, a 29-point advantage; grade 7 math was also strong at 63% versus 38%, 25 points higher. Grade 6 math is the clearest weak spot, at 27% versus 37% statewide, 10 points lower. ELA was also notably stronger than the state in grades 7 and 8, at 71% and 70%, compared with about 50% statewide in each grade. In contrast, grade 5 math was nearly even with the state, at 37% versus 37% (a 0-point gap when rounded).

Results changed in different directions from 2024–25 to 2025–26: ELA proficiency fell by 5 points and math by 4 points, while science rose by 9 points. Even after those declines, all three overall results remained above state levels; science shifted from 1 point below the state to 5 points above. SchoolDigger’s ranking also weakened, moving from the 76th percentile and 4 stars in 2023–24 to the 67th percentile and 3 stars in 2025–26. For context, the school’s student-teacher ratio was 24.3 in 2024–25, and 35% of students were free/reduced lunch eligible that year. Chronic absenteeism was 12% in 2025–26, 7 points below the statewide rate.
