Summary

Cobb Horizon High School is a public high school located in Atlanta, Georgia, serving grades 6-12 with a total enrollment of 1,027 students. It is part of the Cobb County School District, which is ranked 54 out of 206 districts in Georgia and has a 4-star rating from SchoolDigger. However, over the past 5 school years, Cobb Horizon High School has consistently ranked in the bottom half of Georgia high schools, with a 1-2 star rating from SchoolDigger.

Cobb Horizon High School significantly underperforms compared to the Cobb County and Georgia averages across all Milestones Assessment subjects and grade levels. For example, in 2024-2025, only 20.1% of Cobb Horizon students were proficient or better in American Literature and Composition, compared to 52.8% in Cobb County and 40.4% statewide. Additionally, Cobb Horizon High School has had 4-year graduation rates ranging from 58.1% to 87.9% over the past 5 years, which is lower than the Cobb County average of 85.4%. The school also has a relatively high percentage of students receiving free or reduced-price lunch, ranging from 15.65% to 23.47% over the past 3 years, which is higher than the district average.

Cobb Horizon High School significantly underperforms compared to other high schools in the Cobb County district, such as Sprayberry High School, Walton High School, and Campbell High School, which have much higher test scores, graduation rates, and SchoolDigger rankings. While Cobb Horizon High School has lower student-teacher ratios and slightly higher spending per student compared to the district average, these factors do not seem to be translating into better academic outcomes for the school. Addressing the persistent underperformance at Cobb Horizon High School should be a priority for the Cobb County School District.

Saturday, May 16, 2020

I supposedly graduated in December.. I attended the ceremony, my name was called and I didn't receive my diploma afterwards. I was told I had to pick it up at the school, so when I went to the school they told me I had to come back because i "was missing a credit".. I went to the district with my mom to let them know what was happening and they had no idea about this so then when the principal found out I had went he gave me a call NOW just to yell at me and had my number the whole time but never reached out to me before.. 5 months later and I still haven't received anything and I contacted the principal and still haven't had a reply.
