Summary:
Schools in ZIP code 96021 include 11 schools—seven elementary, one middle and three high schools, including alternative high school options—with 2025–2026 test results available for most. The strongest schools approach or exceed state results in some subjects, but the unweighted averages across reported schools were about 25% in ELA, 16% in math and 16% in science, compared with state rates of 49%, 38% and 36%. The most important takeaway is that school performance varies widely, and the average reported school was 20 to 24 percentage points below the state rate, depending on the subject.
Richfield Elementary stands out overall: it led schoolwide ELA at 48% and science at 39%, and ranked second in math at 29%. Its science rate was 3 percentage points above the state, while its ELA was 2 points below; math remained 10 points below. Kirkwood Elementary led math at 36%, but its science result was 13%. At the low end, Centennial Continuation High and Corning Independent Study each reported 0% in ELA and math; Independent Study also reported 0% in science. SchoolDigger ranked Richfield in the 48th statewide percentile and Kirkwood in the 38th; both alternative high schools were at the 0th percentile.
Recent changes are mixed, with the paired-school averages nearly flat in ELA and science and down 2 percentage points in math, while state rates improved in all three subjects. Individual gains include Woodson Elementary’s 9-point science increase and Richfield’s 13-point science increase. Woodson also rose from the 17th to the 23rd SchoolDigger percentile between 2023–2024 and 2025–2026. Its results are stronger than Olive View Elementary’s despite similar free/reduced lunch eligible shares in school year 2024–2025: 89.5% at Woodson and 89.6% at Olive View. Woodson’s ELA, math and science rates were 28%, 26% and 23%, compared with Olive View’s 23%, 16% and 8%. Columbia Academy’s test results are suppressed, and no science result is listed for Rancho Tehama.
