Summary:
ZIP code 97412 covers the rural Blachly area in Oregon's Coast Range and contains exactly one school: Triangle Lake Charter School, a K–12 campus serving 416 students and the only school in Blachly School District 90. Because the district has just this one school, district-level numbers are identical to school-level numbers, so the meaningful comparison point is the state of Oregon, not a set of local peers. About 68.99% of students qualify for free or reduced-price lunch, and per-student spending is $16,156 with a 23.2-to-1 student–teacher ratio.
The school's profile points in two different directions. On completion measures it beats the state clearly: a 93.3% graduation rate against Oregon's 83.0%, and chronic absenteeism of 25.6% against 33.5% — meaning roughly a quarter fewer students are chronically absent than statewide. On test proficiency, however, it trails the state at the All-Grades level in every subject: 33.0% versus 43.8% in English language arts, 22.9% versus 32.9% in math, and 23.3% versus 30.6% in science. The one bright spot is 6th-grade math, at 36.8% proficient versus 29.7% statewide. The sharpest weak points are 3rd-grade math, at 5.3% against 41.3%, and 8th-grade science, at 10% against 27.7%.
Parents should note two things about how to read these numbers. First, the state suppresses four test results — 8th- and 11th-grade ELA and math — to protect student privacy; those are unknown, not zero, and no figure should be assumed for them. Second, the data mixes school years: test scores are from 2025–26, while graduation, attendance, spending, and staffing are from 2024–25. The file also provides no state benchmark for spending, poverty, or class size, so those figures can't be judged as high or low from this data alone.
