Best High Schools in Zip Code 30135

ZIP code 30135 in Douglasville, Georgia, is home to three public high schools—New Manchester High School, Alexander High School, and Chapel Hill High School—all serving grades 9–12 within the Douglas County School District, which ranks in the middle of Georgia districts.

Each school has a distinct academic strength. Chapel Hill High School stands out for its remarkable Algebra I turnaround, jumping from 36.2% to 54.2% proficiency—now well above both district and state averages—and it also leads the group with a 94.6% graduation rate and the lowest dropout rate at 1.5%. Alexander High School is the most consistent performer, excelling in U.S. History (39.8% proficiency, above the state average) and improving its state ranking year-over-year. New Manchester High School posts the highest Biology proficiency (49.3%, above the state average) and holds the top state ranking in the ZIP code, but it also has the lowest graduation rate (89.3%) and highest chronic absenteeism (27.2%). Notably, no single school dominates all subjects, and all three exceed the state graduation rate of 87.2%.

The most pressing concern across the area is chronic absenteeism: all three schools exceed the state rate of 17.7%, with rates ranging from 22.7% at Alexander to 27.2% at New Manchester. This may help explain why test scores in most subjects lag state averages, despite strong graduation outcomes. Per-student spending varies modestly ($11,303 to $12,078) and does not correlate with results—Chapel Hill spends the least yet achieves the best graduation rate. Student-teacher ratios are nearly identical (18.3–18.7), so class size is not a differentiator. Year-over-year trends show all three schools improved in Algebra I and Biology but declined in U.S. History, suggesting a district-wide STEM emphasis. For parents, this area offers solid graduation rates and pockets of academic excellence, but chronic absenteeism is a systemic issue worth monitoring.
