Summary:
ZIP code 97133 covers North Plains, Oregon, a small community west of Portland served by just two public schools — both elementary schools teaching grades K–6, and both part of Hillsboro School District 1J. There are no middle or high schools in this ZIP, so families here continue elsewhere in the district after 6th grade. Both schools perform above district and state averages, but they are not equal in results.
Atfalati Ridge is the standout. It ranks 72 out of 709 schools statewide — the 90th percentile, 4 stars — and has stayed in the 88th–92nd percentile range for three straight years. Its all-grades proficiency is 64.0% in ELA, 58.2% in math, and 51.9% in science, above both district and state averages, and it leads North Plains in every reported grade-level comparison, with the biggest gaps in 5th and 6th grade math (about 25 points each). Chronic absenteeism is 18.7%, the student-teacher ratio is 15.7, and 71.29% of students qualify for free/reduced lunch.
North Plains Elementary School ranks 239 out of 709 — 66th percentile, 3 stars. It still beats district and state averages in all three subjects (ELA 47.8%, math 43.0%, science 42.9%) and has strong pockets such as 5th grade ELA at 64.0%, but its rank has slipped from 153/710 and the 78th percentile three years ago, dropping from 4 stars to 3. Absenteeism is 21.4%, the student-teacher ratio is 18.1, and per-student spending is reported at $21,799 versus $6,885 at Atfalati Ridge. Notably, the school with the higher free/reduced lunch rate and lower reported spending posts the stronger results — spending figures shouldn't be read as a simple predictor of outcomes. Bottom line: both schools exceed district and state averages, but Atfalati Ridge leads clearly on rank, proficiency, attendance, and class size.
