Summary

Grossmont High is a large, traditional public high school serving approximately 2,172 students in grades 9-12 within the Grossmont Union High district in La Mesa, California.

Academically, the school shows a mixed profile: its performance in English Language Arts (56% proficient) is solid and exceeds both state and local averages, outperforming nearby schools like El Cajon Valley High and Monte Vista High. However, math proficiency is a significant and persistent challenge at 25%, which is below the state average. The school's overall statewide ranking has declined in recent years. On a positive note, Grossmont High demonstrates particular strengths in supporting its Special Education students, English Language Learners, and Homeless student population, with these groups performing well above average.

Two key areas of concern are the graduation and dropout rates. The 82% graduation rate is below state and district averages, and the 16% dropout rate is double the state average. While this dropout rate is better than some district alternative schools like Chaparral High, it is much higher than at the high-performing Helix High in a neighboring district. Compared to other schools in its own district, Grossmont is a mid-performer, situated between exceptional schools like Grossmont Middle College High and others that are struggling significantly.
