Riverdale Grade School vs Llewellyn Elementary School

Llewellyn Elementary School and Riverdale Grade School are two of Oregon's top-performing schools, separated by just 2.6 miles and 0.2 rating points. Llewellyn holds a 9.3/10 overall to Riverdale's 9.1/10. In state rank, Llewellyn sits at #22 of 1,226 Oregon schools while Riverdale lands at #40 of 1,226 — both firmly elite, but Llewellyn edges ahead by 18 positions.

Academic scores are identical: both Llewellyn Elementary School and Riverdale Grade School earn 9.9/10, meaning neither school has a meaningful advantage in tested proficiency. The gap opens on growth. Llewellyn's growth score is 9.0/10 versus Riverdale's 8.6/10 — a 0.4-point difference suggesting Llewellyn is advancing students at a measurably faster rate relative to their starting points. For families who weight year-over-year academic progression, that delta is the most consequential number between these two schools.

Enrollment is nearly identical — 393 students at Llewellyn and 400 at Riverdale — so neither school is dramatically larger. Student-teacher ratio follows the same close pattern: 15.7:1 at Llewellyn versus 16.0:1 at Riverdale. That fractional difference in class size is unlikely to produce a noticeable classroom experience gap, and both ratios reflect genuinely small class environments relative to Oregon norms.

The most structurally meaningful distinction is grade span. Llewellyn Elementary School serves kindergarten through fifth grade only, after which students transition to a separate middle school. Riverdale Grade School runs kindergarten through eighth grade, keeping students in the same building through early adolescence. Families who prefer consistency of campus, staff relationships, and community across the elementary and middle years will find Riverdale's K–8 model a meaningful advantage — independent of rating differences.
