Arroyo Seco Museum Science vs Charles H. Kim Elementary

Charles H. Kim Elementary outranks Arroyo Seco Museum Science by a substantial margin within California: Kim sits at #9 of 9533 schools statewide while Arroyo Seco ranks #180 — a gap that reflects meaningfully different performance ceilings even though both schools score well above average. The overall rating difference is 0.5 points, with Kim at 9.6/10 against Arroyo Seco's 9.1/10, but the state rank gap tells the more striking story. Both schools are located in Los Angeles, California, roughly 6.3 miles apart, yet that distance translates to a dramatically different competitive position within one of the nation's largest and most crowded school markets.

Academically, Charles H. Kim Elementary scores 9.5/10 against Arroyo Seco Museum Science's 9.0/10 — a half-point difference that mirrors the overall gap and suggests the advantage is consistent across measures rather than driven by a single outlier. Growth scores follow the same pattern: Kim posts 9.8/10 compared to Arroyo Seco's 9.4/10, meaning students at Kim are not just starting from a higher baseline but are also advancing at a faster measured rate year over year. For families prioritizing academic trajectory as much as snapshot proficiency, that growth delta is the number worth anchoring on.

Charles H. Kim Elementary serves a higher-need population — 88% of students qualify for free or reduced lunch versus 72% at Arroyo Seco Museum Science — making its performance advantage even more notable in context. Enrollment is similar (472 at Kim, 428 at Arroyo Seco), but the student-teacher ratio at Kim is tighter: 18.2 students per teacher compared to 20.4 at Arroyo Seco, a difference of 2.2 students per classroom that can affect individualized attention in a meaningful way at the elementary level.

The two schools diverge sharply on grade configuration. Arroyo Seco Museum Science runs KG through grade 8, keeping students through middle school in a single campus environment. Charles H. Kim Elementary covers only KG through grade 5, requiring a school transition after fifth grade. Arroyo Seco's museum-science identity also suggests a distinct instructional focus that Kim, as a more conventional elementary, does not replicate.
