Summary
Discovery Elementary is a K–5 school serving 648 students in Everett, Washington, in the Mukilteo School District, near several other elementary schools, including Olivia Park Elementary, just 0.52 miles away. The school has a relatively favorable student-teacher ratio of 13.9 to 1, but its academic results are considerably below district and state averages. In 2025–2026, 28.76% of students were proficient in English language arts, 23.53% in math, and 23.96% in science. Discovery ranked 1,015th of 1,138 Washington elementary schools, in the 11th percentile.
Science is the school’s largest current weakness: Discovery’s 23.96% proficiency rate was about 25 percentage points below the Mukilteo district and less than half the statewide rate. Math also declines notably by grade, from 32.69% proficiency in third grade to 15.63% in fifth grade. Results are generally among the lowest of nearby Mukilteo schools. For example, Challenger Elementary and Lake Stickney Elementary School each had math proficiency near 40%, compared with Discovery’s 23.53%. Discovery’s performance is also well behind nearby Silver Lake Elementary, which posted 52.36% ELA, 57.51% math, and 59.15% science proficiency.
The school’s economic-need level is elevated, with 63.43% of students qualifying for free or reduced-price lunch, but nearby schools serving similar or higher percentages sometimes achieve stronger results. Emerson Elementary School, for instance, had a higher rate of 74.47% but substantially stronger proficiency, particularly in science at 58.54%. Discovery’s latest ranking improved modestly from the 9th percentile the previous year, though its longer-term results remain persistently low. Low subgroup effectiveness rankings—especially the 0th percentile for special education students and 6th percentile for English Language Learners—point to a need to examine instructional consistency, interventions, and student supports. Its staffing ratio and spending are comparatively solid, making schoolwide teaching practices and resource use important areas for improvement.
