Summary

Kennesaw Mountain High School is a large public high school in Kennesaw, GA, serving 1,695 students in grades 9-12 as part of the Cobb County School District, and it has earned a reputation as one of the top-performing schools in the northwest Atlanta metro area.

This school is a standout for good reason. It holds a 5-star rating and ranks 39th out of 455 high schools in Georgia, placing it in the top 10% statewide—a position it has maintained for the past decade. Its graduation rate is exceptionally strong at 94.5%, well above the district (89.2%) and state (87.2%) averages, and its dropout rate of 1.1% is less than half of both. Academically, the school shines in STEM subjects: 73.4% of students are proficient in Biology (15 points above the district and 26 points above the state), and Algebra I proficiency sits at 66.4%. What truly sets Kennesaw Mountain apart, however, is its consistency across all student groups. The school earned 5-star ratings for every reported subgroup, including a remarkable 97th percentile ranking for Special Education students and a 95th percentile ranking for African American students. This shows that high achievement is not limited to a few—it is a school-wide norm.

Compared to nearby schools, Kennesaw Mountain is a clear leader. It outperforms Kell High School (ranked 57th), Allatoona High School (61st), and North Cobb High School (85th) in overall ranking. Its closest rival is Harrison High School (ranked 22nd), but Kennesaw Mountain serves a far more economically diverse student body—40.6% of its students receive free/reduced lunch versus Harrison’s 16.0%—while achieving nearly identical outcomes. The school also keeps chronic absenteeism (15.7%) below the state average and significantly lower than nearby Sprayberry High School (20.7%). For parents seeking a school that combines elite academics, strong graduation rates, and genuine equity across all learners, Kennesaw Mountain is an outstanding choice.
