Skyline Elementary School vs Portland Arthur Academy Charter School

Skyline Elementary School and Portland Arthur Academy Charter School both rank among Oregon's top 40 schools out of 1,226, but Skyline holds a slim edge: an overall rating of 9.4/10 versus Portland Arthur Academy Charter School's 9.2/10, placing Skyline at #24 statewide and Portland Arthur Academy at #37. That 0.2-point gap is narrow but consistent across every subscale, suggesting neither school is a clear outlier — both simply outperform the overwhelming majority of Oregon elementary schools.

Academically, the delta is modest but real. Skyline Elementary School scores 9.6/10 on academics against Portland Arthur Academy Charter School's 9.3/10 — a 0.3-point difference. Growth scores follow the same pattern: Skyline at 9.2/10 versus Portland Arthur Academy at 9.0/10. Both schools are driving measurable student growth above state norms, but Skyline's 0.2-point growth advantage suggests its students are progressing at a slightly faster clip relative to academic starting points.

The demographic and classroom-environment differences are where the two schools diverge more meaningfully. Portland Arthur Academy Charter School serves a higher proportion of economically disadvantaged students — 30% qualify for free or reduced lunch compared to 16% at Skyline Elementary School — which makes its strong ratings particularly notable. Portland Arthur Academy also offers a more intimate classroom setting: a student-teacher ratio of 16.4:1 versus Skyline's 18.2:1, despite smaller total enrollment of 164 students compared to Skyline's 218.

One structural difference matters for families with older children. Skyline Elementary School runs from kindergarten through 8th grade, meaning students can stay through middle school without a transition. Portland Arthur Academy Charter School serves only kindergarten through 5th grade, so families will need to plan a school change at the elementary-to-middle transition. The two schools sit 14.5 miles apart, and Portland Arthur Academy's charter status gives it a distinct admissions and governance model compared to Skyline's status as a regular public neighborhood school.
