Rieke Elementary School vs Portland Arthur Academy Charter School

Rieke Elementary School and Portland Arthur Academy Charter School both rank among Oregon's top elementary schools, but Rieke holds a measurable edge: a 9.4/10 overall rating versus Portland Arthur Academy's 9.1/10, placing Rieke #13 of 1226 schools statewide while Portland Arthur Academy Charter School lands at #39 of the same 1226. That 26-position gap in state rank represents a meaningful difference at the top of the distribution, where schools are clustered closely together.

The academic and growth numbers sharpen that distinction. Rieke Elementary School scores a perfect 10.0/10 on academics compared to Portland Arthur Academy Charter School's 9.3/10 — a 0.7-point difference that reflects measurable proficiency advantages. On growth, which captures how much students improve regardless of starting point, Rieke scores 9.9/10 against Portland Arthur Academy's 9.0/10. That near-perfect growth score means Rieke students are advancing at an exceptional rate, not merely benefiting from an advantaged baseline population.

The two schools serve noticeably different student populations. Rieke Elementary enrolls 288 students at a 19.2:1 student-teacher ratio, while Portland Arthur Academy Charter School serves 164 students at a 16.4:1 ratio — nearly three fewer students per teacher. Portland Arthur Academy also serves a higher share of economically disadvantaged students: 30% qualify for free or reduced lunch versus 17% at Rieke. That difference matters for interpreting both schools' scores; Portland Arthur Academy's 9.1/10 overall rating is achieved with a harder-to-serve population and smaller class sizes that reflect a deliberate structural choice.

Both schools cover grades KG–05 and sit six miles apart within Portland. The key structural distinction is school type: Rieke Elementary School operates as a traditional neighborhood public school, while Portland Arthur Academy Charter School is a charter, meaning families must actively choose and apply rather than enroll by attendance zone. That charter model enables Portland Arthur Academy's smaller enrollment and lower student-teacher ratio, and shapes the community it attracts.
