Summary

Mount Si High School is a large, top-ranked public high school serving over 2,150 students in grades 9-12 within the highly-regarded Snoqualmie Valley School District.

The school consistently ranks among the best in the state, with a stellar 96% graduation rate and particularly strong student performance in English and Science. A key strength is its exceptional support for Hispanic students, where it ranks in the state's 98th percentile, demonstrating effective, equitable education. It also shows a unique pattern where male students consistently perform at a very high level. While the school excels overall, its math scores, though solid, are an area for growth compared to some nearby peers like Skyline High School or Issaquah High School.

Mount Si achieves these excellent results efficiently, spending moderately per student compared to other schools. Its success is stable and long-term, suggesting strong systems and leadership. While it operates in a competitive area with specialized schools like Nikola Tesla STEM High School, Mount Si stands out as a model of a comprehensive high school that delivers high-quality education for all its students, outperforming even its own high-achieving district in several subjects.

My son graduated last year and got a great education from Mount Si. He had lots of class options, learned in a culture of respect, and earned admission to the University of Washington this fall. I am grateful for the school that clearly cares about its students and works hard to help set them up for success. Close Quote

There is a path for a wide variety of students at this comprehensive school. From many AP courses to choose from to quality vocational courses in culinary arts, horticulture, construction and others. It has been a pleasure to have my children in this district. Close Quote
