The school's performance is particularly strong for certain student subgroups, such as ranking 32nd out of 352 Colorado middle schools for male students and 20th out of 275 Colorado middle schools for white students, both with 5-star ratings.

When compared to the nearby Ignacio Middle School and Bayfield Middle School, Mountain Middle School significantly outperforms these schools in academic assessments and overall school rankings.

While the school excels in most areas, its performance for gifted and talented students is relatively lower, which could be an area for the school to focus on and improve.

Could be a great school. Poor leadership that does not know how to deal with teenagers, especially boys. Not free, really, as so much out of pocket stuff just to complete assignments. A few really great teachers, but again, this is overshadowed by unreasonable leaders. Close Quote
