Summary:
Zip code 30022, spanning the Johns Creek and Alpharetta areas of Georgia, is home to two top-tier public high schools—Johns Creek High School and Chattahoochee High School—both serving grades 9-12 within the Fulton County School District.
Both schools are elite by any measure, ranking in the top 6% of all Georgia high schools. Johns Creek High School is the clear academic leader, holding a #14 state ranking (97th percentile, 5 stars) and posting a 97.1% graduation rate with a remarkably low 0.7% dropout rate. It also excels in Algebra I, with 75.1% of students proficient, and maintains a chronic absenteeism rate of just 11.3%—well below the state average of 17.7%. Chattahoochee High School is also outstanding, ranked #27 in the state (94th percentile, 5 stars) with a 97.0% graduation rate. However, it has slipped from its #17 ranking the previous year, largely due to a notable 6.7-point drop in Algebra I proficiency (from 70.7% to 64.0%). Despite this, Chattahoochee actually outperforms Johns Creek in Biology (79.6% vs. 76.8% proficient) and had stronger American Literature scores in the prior year.
Both schools serve relatively affluent populations, with free/reduced lunch rates of 12.1% at Johns Creek and 16.3% at Chattahoochee, and they dramatically outperform district and state averages across nearly every metric. Interestingly, Chattahoochee spends slightly more per student ($15,135 vs. $14,813) and has a better student-teacher ratio (16.5:1 vs. 18.3:1), yet Johns Creek still holds the academic edge—suggesting factors like school culture and student engagement play a significant role. For families in this area, both schools offer exceptional opportunities, with Johns Creek High School providing a slight but consistent advantage in overall ranking and college readiness metrics. Note that English Language Arts scores are not yet available for this release and will be published in December.
