Monroe’s strongest outcomes are in graduation and English Language Arts.

In 2025–2026, ELA proficiency reached 69.11%, well above the district’s 53.20% and the state’s 52.81%. That result was higher than Snohomish High School and similar to Sultan Senior High School, though below Cedarcrest High School, Glacier Peak High School, North Creek High School, and Woodinville High School.
Mathematics is Monroe’s clearest challenge: 39.02% of students were proficient, below both the district’s 43.42% and the state’s 43.11%, despite improvement from 22.73% in 2023–2024. Science proficiency recovered to 50.98%, nearly matching the state average. Compared with nearby schools, Monroe is ahead of Sultan in math but trails the higher-performing comprehensive schools by sizable margins. The school’s recent gains are broad, including improved ELA, math, science, graduation, and several subgroup results. However, effectiveness for students receiving special education services fell to the 25th percentile, making it another important focus. Overall, Monroe offers solid completion outcomes and notably strong ELA performance, with targeted improvement in math and special education likely to have the greatest impact.
