The data story: Peninsula Elementary School vs Winterhaven School
Peninsula Elementary School and Winterhaven School sit 6.5 miles apart in Portland, Oregon, and their overall ratings are nearly identical — 9.2/10 for Peninsula Elementary School versus 9.1/10 for Winterhaven School. In state terms, Peninsula ranks #29 of 1,226 Oregon schools and Winterhaven ranks #38 of 1,226, placing both firmly in the top 3% statewide. The gap at the top of the list is negligible; the meaningful differences lie in the categories underneath that headline number.
Academically, the two schools diverge sharply. Winterhaven School earns a perfect 10.0/10 academic score compared to Peninsula Elementary School's 8.2/10 — a 1.8-point gap that reflects measurably higher tested proficiency at Winterhaven. Peninsula counters with a stronger growth score: 9.9/10 versus Winterhaven's 9.6/10, meaning students at Peninsula are advancing at a faster rate relative to similar peers, even if their absolute proficiency ceiling starts lower. Families who weigh trajectory and value-add alongside raw achievement will read those two numbers differently.
The demographic and structural profiles of the two schools differ considerably. Peninsula Elementary School enrolls 234 students with a student-teacher ratio of 15.6:1 and serves a high-need population — 64% of students qualify for free or reduced lunch. Winterhaven School is larger at 315 students, carries a 19.7:1 student-teacher ratio, and has a 23% free/reduced lunch rate. Peninsula's smaller classes mean more direct teacher contact per child, a tangible daily difference of roughly four additional students per teacher at Winterhaven.
The grade span is the most concrete structural distinction. Peninsula Elementary School serves grades KG–05, so families will face a middle school transition after fifth grade. Winterhaven School runs KG–08, keeping students through eighth grade and eliminating one school transition entirely. That continuity can matter for families who value stable peer cohorts and a single school community through early adolescence.
