Best Public Schools in Zip Code 30021

ZIP code 30021 in Clarkston, Georgia, is served by four schools—two elementary schools, one high school, and one specialized state-operated school—that together enroll roughly 3,300 students, with all three traditional schools in the DeKalb County district reporting 100% of students qualifying for free/reduced lunch.

The standout story here is Clarkston High School, which has made a remarkable turnaround, jumping from the 15th to the 53rd percentile in state rankings over two years and improving from a 1-star to a 3-star rating. Its End of Course proficiency rates climbed sharply, with Biology nearly doubling to 43.2% and Algebra I rising to 40.7%. However, the school still faces serious challenges: chronic absenteeism sits at 42.6%—more than double the state average—and its graduation rate of 67.1% trails the state by 20 points. Among the elementary schools, Indian Creek Elementary School consistently outperforms Jolly Elementary School despite identical demographics and similar spending. For example, Indian Creek’s 4th grade math proficiency (33.6%) is more than double Jolly’s (16.3%), and Indian Creek’s chronic absenteeism rate of 16.8% is actually below the state average, while Jolly’s is 28.6%. Atlanta Area School for the Deaf, part of the State Schools district, offers an intensive 3.3:1 student-teacher ratio but reports a 33.3% graduation rate and very low test proficiency, though its specialized mission makes direct comparisons difficult.

All three traditional schools spend well above the state average per student—between $18,234 and $19,406—yet proficiency rates in most subjects remain below state averages, highlighting that funding alone cannot overcome the effects of concentrated poverty. The ZIP code also has no middle school, forcing students to leave the area during a critical transition period. For parents, the key takeaway is that Indian Creek Elementary and Clarkston High School show promising momentum, while Jolly Elementary and the high school’s attendance and graduation metrics point to a need for stronger non-academic supports.
