Summary:
Foster, Oregon has one elementary school in this data set: Foster Elementary School, which serves grades K–6, enrolls 277 students, and belongs to Sweet Home School District 55. Because there is only one elementary school in the city, there are no in-city school-to-school comparisons; the useful comparisons are to the district and state. The school’s profile is mixed, with a strong 3rd grade cohort but notable gaps in science, upper-elementary math, and student attendance.
In 2025–2026 OSAS testing, all-grade proficiency was below both district and state: ELA was 36.9% at the school vs. 37.4% in the district and 43.8% statewide; math was 25.1% vs. 28.9% and 32.9%; and science was 5.1% vs. 20.8% and 30.6%. The standout bright spot is 3rd grade, where ELA proficiency was 51.1% vs. 42.9% district and 41.5% state, and math was 44.4% vs. 40.7% and 41.3%. By contrast, 4th grade math was 14.0% vs. 31.6% and 38.9%, 5th grade math was 10.0% vs. 22.8% and 32.4%, and 5th grade science was 5.1% vs. 23.5% and 30.8%. Sixth grade math was near the state at 29.8% vs. 29.7%, though slightly below the district’s 30.9%.
Other context matters for parents. Chronic absenteeism in 2024–2025 was 42.1%, above the district’s 40.2% and well above the state’s 33.5%. About 75.09% of students were eligible for free/reduced lunch, per-student spending was $15,140, and the student-teacher ratio was 16.2. The school’s rank has also declined across the reported years, from 325 out of 710 (54th percentile, 3 stars) in 2023–2024, to 412 out of 706 (42nd percentile, 2 stars) in 2024–2025, and to 490 out of 709 (31st percentile, 2 stars) in 2025–2026. Overall, the school shows a clear 3rd grade strength, but the broader picture includes below-district and below-state proficiency, a large science gap, high absenteeism, and a declining rank trend.
