Summary

Dilley Elementary School is a small K–4 school in Forest Grove, Oregon, serving about 201 students as part of Forest Grove School District 15, a district ranked 102nd of 141 in Oregon. Despite that district standing, Dilley itself ranks 119th of 709 Oregon schools in 2025–2026 (83rd percentile, 4 stars). It serves a high-poverty population: 81.09% of students were eligible for free/reduced lunch in 2024–2025, up from 63.32% the year before and 18.93% in 2022–2023. Per-student spending was $19,269, with a student–teacher ratio of 17.1.

Academically, Dilley is well above both its district and the state. In 2025–2026, 55.9% of tested students were proficient in English Language Arts and 61% in math, compared with district rates of 33.1% and 22% and state rates of 43.8% and 32.9%. Dilley outperforms every nearby school in both subjects, including Gaston Elementary School, Farmington View Elementary School, Forest Grove Community School, W Verne McKinney Elementary School, Harvey Clarke Elementary School, Joseph Gale Elementary School, Fern Hill Elementary School, Echo Shaw Elementary School, Cornelius Elementary School, and Free Orchards Elementary School. Math is the standout: third-grade math proficiency is 74.1%, versus 32% in the district and 41.3% statewide.

Chronic absenteeism was 28.7% in 2024–2025, better than the district's 35.6% and the state's 33.5%, though it rose from 20.5% the previous year and is worth watching. School-effectiveness rankings show strong results for female students (90th percentile, 5 stars) and above-average results for male students (70th percentile, 3 stars), along with above-average historical rankings for low-income students. Notably, Dilley spends less per student than several nearby schools with lower scores, including Joseph Gale, Echo Shaw, Fern Hill, Harvey Clarke, and Cornelius, suggesting the results aren't simply about smaller classes or bigger budgets.
