Summary:
ZIP code 97133 is home to two elementary schools, both serving grades K–6 within Hillsboro School District 1J: North Plains Elementary School with 235 students and Atfalati Ridge with 209 students, for a combined 444 students. The district itself ranks 69th of 141 in Oregon, at the 51st percentile with 3 stars, placing it roughly middle-of-the-pack statewide — yet both of these schools perform above the district average in the available metrics.
Atfalati Ridge is the standout. It ranks 72nd of 709 Oregon elementary schools in 2025–2026, the 90th percentile with 4 stars, and has stayed near the top for three years (88th percentile in 2024–2025 and 92nd percentile with 5 stars in 2023–2024). Its proficiency is strong and consistent: 64.0% in ELA, 58.2% in math, and 51.9% in science — above district and state in every reported subject and grade level. Its ELA scores range from 60.7% to 69.2% and its math scores from 50.0% to 65.4%. It also reports the lower chronic absenteeism of the two (18.7%) and a smaller student-teacher ratio (15.7).
North Plains Elementary School is also above district and state overall — 47.8% in ELA, 43.0% in math, and 42.9% in science — but it ranks 239th of 709, the 66th percentile with 3 stars, down from the 78th percentile three years ago. Its brightest spots are 3rd grade math (59.0%) and 5th grade ELA (64.0%), while math slips in the upper grades and 4th grade ELA falls below both district and state. Both schools report lower chronic absenteeism than the district's 31.8% and the state's 33.5%. The large reported spending gap between the schools ($21,799 versus $6,885 per student) is striking but should be viewed cautiously, as school-level spending figures can reflect differences in how costs are reported.
