Zip code 94558 has 18 schools—11 elementary, three middle, three high and one alternative; 17 have 2025–26 all-grades results, while Stone Bridge’s latest scores are from 2024–25. The area’s school averages trail the state by 11 percentage points in ELA, 8 in math and 9 in science, but those averages hide large differences: the gap between the highest- and lowest-scoring schools ranges from 48 points in ELA to 63 in math. The main takeaway is that families will find sharply different results among schools in the same zip code.

Northwood Elementary leads in science at 56%, 20 points above the state; Pueblo Vista Elementary is also strong in math (60%) and science (47%).

Recent changes are mixed: across the 17 schools with year-to-year data, average ELA proficiency fell 3 points from 2024–25 to 2025–26, while math rose 1 point and science rose 3. SchoolDigger ranks Northwood at the 76th percentile and Vichy at the 78th among state elementary schools; Valley Oak is at the 7th percentile among high schools. Attendance provides another point of comparison: chronic absenteeism is 60% at Valley Oak, versus 6% at Pueblo Vista and 20% at Northwood. The reported low-income measure is free/reduced lunch eligible for 2024–25; it is 50% at Northwood, 55% at Pueblo Vista and 91% at McPherson Elementary, whose ELA result is 18%. These broad all-grades comparisons are not fully like-for-like because schools serve different grade spans.
