Schools in Zip Code 95428

Zip code 95428 has four schools: two elementary schools and two high schools, serving grades K–12 across spans from K–6 to grades 10–12. Test scores are supplied for only some schools and years. The clearest overall concern is that every reported all-grades proficiency result is below its state comparison; in 2025–26, the two schools with scores averaged 40 percentage points below the state in ELA, 34 points below in math and 31 points below in science.

Among schools with 2025–26 scores, Round Valley Elementary led in all three subjects, with 11% proficient in ELA, 8% in math and 9% in science; Round Valley High recorded 8% in ELA and 0% in math and science. In 2024–25, Eel River Charter led science at 9%, while Round Valley High led ELA at 21%. Completion outcomes tell a different story: Round Valley High’s 95% graduation rate exceeded the state’s 88%, and its 5% dropout rate was below the state’s 8%. Yolla Bolly Continuation High had the most concerning supplied attendance and completion figures: 100% chronic absenteeism, 75% graduation and 25% dropout.

Results shifted in opposite directions at the two Round Valley schools: from 2024–25 to 2025–26, Round Valley Elementary improved by 1 point in ELA, 3 in math and 6 in science, while Round Valley High fell by 13, 5 and 5 points, respectively. SchoolDigger’s percentile ranking rose for the elementary school from 1 to 4 across its listed years, but fell for the high school from 17 to 2. All four schools reported free/reduced lunch eligible for 2024–25, ranging from 89% at Round Valley High to 95% at Yolla Bolly; student–teacher ratios ranged from 9.9 at Round Valley High to 30.4 at Yolla Bolly. These are contextual differences, not explanations for school results, and all-grades scores should not be read as like-grade comparisons.
