Summary:
ZIP code 97055 — covering Sandy, Boring, and Welches, Oregon — is home to six elementary schools, five serving grades K–5 and one serving K–8, all within Oregon Trail School District 46, which itself ranks among the top 15 of 141 Oregon districts. Combined enrollment is 1,817 students, with individual schools ranging from 172 to 430.
Oregon Trail Academy is the clear standout: ranked 38th of 709 Oregon elementary schools (95th percentile, 5 stars) — the only school here in the state's top 5% — with 74.8% ELA, 59.6% math, and 57.9% science proficiency, plus the group's lowest chronic absenteeism at 15.6%. Among the traditional K–5 schools, Sandy Grade School leads at 159th of 709 (78th percentile, 4 stars), posting the highest K–5 math score (52.5%) and steady three-year improvement. At the other end, Welches Elementary has slid from 90th percentile (5 stars) two years ago to 72nd percentile (4 stars), and now shows the weakest K–5 math result (45.6%).
Four of the six schools are trending down in state rank, and only Oregon Trail Academy and Sandy Grade are improving. Science is the area's soft spot: the district's science rate is below the state's, and only three of six schools clear the state mark. Spending and class size show no clear relationship to results here — the highest-spending, smallest-class school is not the top performer. Every school does beat the district and state chronic absenteeism rates, a genuine strength for the area.
