Summary:
ZIP code 94596 has three schools serving 2,455 students: Las Lomas High (grades 9–12) and Murwood Elementary and Walnut Heights Elementary (both K–5). In 2025–26, all three schools exceeded California’s proficiency rates in ELA, math, and science. The clearest elementary-school distinction is that Walnut Heights led Murwood in all three all-grade subjects.
Walnut Heights has the strongest all-grade results among the elementary schools: it scored 72% in ELA, 68% in math, and 61% in science, compared with Murwood at 66%, 65%, and 52%—gaps of 6, 3, and 10 percentage points. Both schools were well above California’s rates, including in math: 65% and 68%, versus 38% statewide. Murwood has a clear grade-specific exception: in fourth grade, it led Walnut Heights by 8 points in ELA and 6 in math. Las Lomas also exceeded state rates, with leads of 18 points in ELA, 12 in math, and 16 in science; because it serves high school grades, its results should not be ranked directly against the elementary schools.
Recent results are mixed: from 2024–25 to 2025–26, Walnut Heights improved by 3 points in ELA and 11 in science but fell 6 in math; Murwood declined by 4 in ELA, 1 in math, and 10 in science. Las Lomas fell by 4, 6, and 6 points in those subjects, respectively, though it remains above state proficiency. SchoolDigger placed all three in the top 16% statewide in 2025–26: Walnut Heights at the 89th percentile, Las Lomas at the 85th, and Murwood at the 84th. Enrollment and context measures do not explain the differences: Murwood has 451 students and a 22.5 student-teacher ratio, while Walnut Heights has 427 students and a 23.7 ratio. Both report free/reduced lunch eligible figures for 2024–25: 22% at Murwood and 15% at Walnut Heights; Las Lomas reports 15%.
