Summary:
ZIP code 98235 has one listed public school, Clear Lake Elementary School, serving students in kindergarten through sixth grade within the Sedro-Woolley School District. With 314 students, the area does not offer a local middle school, high school, or alternative school in the available list, so families will need to look outside the ZIP code for later grades.
Clear Lake Elementary School is a relatively small school with an 18:1 student-teacher ratio and generally strong academic results compared with both its district and Washington state. In 2025–2026, 58.0% of students were proficient in English Language Arts and 56.2% in math. Those results were 16.2 and 23.1 percentage points above the district, respectively. The school also exceeded statewide averages by 5.2 points in ELA and 13.0 points in math. Fifth-grade ELA was a standout result, with 72% proficiency, while reported math results were above the state in third, fifth, and sixth grades. Third-grade ELA, at 41.7%, was the clearest area for improvement because it fell below the statewide result, even though it exceeded the district.
The school’s statewide ranking improved from the 67th percentile in 2023–2024 to the 72nd percentile in 2025–2026, when it received a four-star rating. ELA improved year over year, while math was essentially stable. About 40.5% of students qualify for free or reduced-price lunch, an important context when considering school outcomes, and reported per-student spending was $17,939 for 2023–2024. Science performance cannot be evaluated fully because the latest school and fifth-grade results were suppressed, as was fourth-grade math. Overall, the available data suggest that Clear Lake Elementary School is a higher-performing school within the Sedro-Woolley School District, with particular strengths in math and upper-elementary ELA.
