Results from the Oregon Statewide Assessment System’s proficiency tests for the 2025-2026 school year were released in late September, revealing a range of outcomes for students in Tillamook’s three school districts.
Proficiency rates in English and language arts (ELA) and math were up in the Tillamook School District, while science scores saw a slight dip, with students scoring within two percentage points of the state average in all three tests.
Neah-Kah-Nie saw across the board improvement, with the most significant progress in science scores, and outpaced statewide average proficiency rates in all three subjects.
Fewer Nestucca students exhibited proficiency in ELA and science testing than had their peers a year prior, while improving slightly in math, though they continued to lag statewide averages across all three tests.
Tillamook’s biggest improvement came in ELA, with overall grade level proficiency rising to 44.5% from 42.2% in the 2024-2025 school year and 27% in the 2023-2024 school year.
