Summary:
Zip code 30117 in Carrollton, Georgia, is served by two public high schools—Carrollton High School and Mt. Zion High School—which together educate about 2,355 students in grades 9-12 across two different districts: Carrollton City and Carroll County.
These two schools offer very different profiles. Carrollton High School is the larger option with 1,859 students and posts stronger academic results across the board—for example, 39.1% proficiency in Algebra I and 45.4% in Biology, compared to Mt. Zion’s 21.8% and 28.4%. Carrollton also has a better state ranking (158th vs. 311th), lower chronic absenteeism (20.8% vs. 26.2%), and higher per-student spending ($13,447 vs. $12,401). Its graduation rate of 92.8% is solid, though below Mt. Zion’s exceptional 99.1%. Mt. Zion High School is much smaller (496 students) and clearly excels at getting students to graduation, but its academic proficiency lags significantly—especially in Algebra I, where fewer than 1 in 4 students are proficient. Both schools exceed the state’s chronic absenteeism average of 17.7%, and both have seen their state rankings slip over the past three years, with Mt. Zion’s decline being steeper.
For parents, the choice comes down to priorities. Carrollton High School offers stronger academics, more resources, and better attendance, making it the stronger all-around performer. Mt. Zion High School stands out for its near-perfect graduation rate, suggesting strong support for students to finish, but families should weigh that against its lower test scores and higher absenteeism. Both schools struggle with math proficiency, and US History is a relative strength at Carrollton. Note that English Language Arts scores are not yet available; they will be released in December, which will provide a fuller picture of each school’s performance.
