Summary:
ZIP code 98648, which includes the Stevenson area of Washington, has one high school: Stevenson High School, serving grades 9–12 with 271 students. Because it is the only high school in the ZIP code, families do not have multiple local high schools to compare directly. The school is part of the Stevenson-Carson School District and offers a relatively small-school setting, with a 20.2-to-1 student-teacher ratio. About 53.51% of students qualified for free or reduced-price lunch, an important factor when considering the resources and support students may need.
Stevenson High School performs especially well in English Language Arts. In 2025–2026, 76.47% of students were proficient, compared with 39.82% in the district and 52.81% statewide. Science was another relative strength, with 54.90% proficiency—above both the district’s 45.33% and the state’s 50.95%. The school’s overall state ranking improved to 74th out of 396 schools, placing it in the 81st percentile, and it maintained a four-star rating. Graduation was 85.5% in 2024–2025, 2.9 percentage points above the Washington average, while the 9.2% dropout rate was slightly below the statewide rate.
Mathematics is the clearest area for improvement. Math proficiency rose from 34.43% in 2024–2025 to 41.67% in 2025–2026, but it remained just below the state rate of 43.11%. Science also declined from an unusually strong 63.64% to 54.90%, although it still exceeded state and district results. Since the school is relatively small, annual percentages can shift noticeably when the number of tested students or graduates changes. Overall, the school offers strong literacy and science outcomes, improving math performance, and graduation results above the state average. Parents may want to ask about math support, credit recovery, attendance services, and programs that help students stay on track to graduate.
