Summary:
Forest Grove School District 15 is home to two high schools serving grades 9–12 — the large comprehensive Forest Grove High School and the much smaller Tuality Plains High School — with a combined enrollment of 1,990 students. The district is ranked 102 of 141 in Oregon, at the 28th percentile with 1 star, and both schools share that district rating.
Forest Grove High School enrolls 1,849 students, roughly 13 times as many as Tuality Plains, and generally posts the stronger results. It graduates 84.0% of students, above the district's 81.2% and the state's 83.0%, and its chronic absenteeism of 36.3% sits near the district and state rates. In 11th-grade testing it reaches 45.8% proficiency in English language arts, 29.6% in science, and 14.3% in math, beating district averages in all three subjects but trailing the state in math by 8.6 points and in science by 4.2 points. After two years at 3 stars and the 56th–58th percentile, it slipped to 2 stars and the 39th percentile in 2025–2026.
Tuality Plains High School serves just 141 students and faces extreme challenges: it graduates 64.4%, a 19.6-point gap with Forest Grove, and 80.9% of its students are chronically absent — more than double the district and state rates. Test proficiency is under 5% in ELA, math, and science, and the state suppressed the exact figures. It also has the highest economic need, at 90.07% free/reduced lunch, and the lowest per-student spending at $5,860, versus $21,397 at Forest Grove, even though student-teacher ratios are similar (19.4 vs. 20.1). Math is a district-wide weakness: the district's 11th-grade rate of 13.3% is the largest gap against the state's 22.9%. With only 141 students, results can swing more easily from year to year.
