Summary:
ZIP code 98513 has one listed high school, River Ridge High School, serving grades 9–12 in Lacey. The school enrolls 1,547 students and is part of North Thurston Public Schools. Because it is the only listed high school in the ZIP code, there is no local school-to-school comparison; the most useful benchmarks are the district, Washington state, and River Ridge’s recent results.
River Ridge has a mixed but improving academic profile. Its strongest area is English language arts: 65.87% of students were proficient in 2025–2026, about 13 percentage points above both the district and state averages. Math and science are more challenging, with proficiency rates of 30.56% and 41.98%, respectively—below district and state levels in both subjects. Still, all three subjects improved from the prior year, with math showing the largest gain of 5.15 percentage points. The school’s ranking also rose from the 40th percentile to the 55th percentile, and its rating increased from two stars to three.
For parents, graduation results are encouraging but should be considered alongside student-retention concerns. River Ridge’s 2024–2025 graduation rate was 84.3%, above Washington’s 82.6% but below the district’s 86.8%. Its 11.0% dropout rate was higher than both the state rate of 9.8% and the district rate of 8.9%, making attendance, engagement, credit recovery, and early intervention important areas to examine. Nearly half of students qualify for free or reduced-price lunch, and the student-teacher ratio is 20.1 to 1, providing useful context when considering support needs. Overall, River Ridge shows positive momentum and notable ELA strength, while math, science, and dropout prevention remain the most important improvement priorities.
