Mountainside High School's academic performance is impressive, with significantly higher proficiency rates on state assessments compared to the Beaverton School District and the state of Oregon in English Language Arts, Mathematics, and Science. For example, in the 2024-2025 school year, 60.9% of 11th-grade students at Mountainside High School were proficient or better in English Language Arts, compared to 53.2% for the Beaverton School District and 44.4% for the state.
