Denmark High School in Alpharetta, GA, is a large public high school serving 2,527 students in grades 9-12 within the highly-ranked Forsyth County School District. The school has earned a 5-star rating for six consecutive years and currently ranks 34th in Georgia (93rd percentile), with a graduation rate of 97.6% that far exceeds the state average of 87.2%.
Denmark stands out for its dramatic improvement in student attendance. The chronic absenteeism rate has plummeted from 25.5% in 2022-2023 to just 6.2% in 2025-2026—a 76% reduction that now beats both the district average (8.2%) and the state average (17.7%). The school also excels in Biology, where 75.3% of students scored proficient, and in U.S. History (53% proficient), both exceeding district and state benchmarks. Notably, Denmark ranks in the 94th percentile statewide for supporting special education students, a rare strength among high-performing schools. The school achieves these results while spending $11,368 per student—considerably less than nearby Cambridge High School ($15,530) and Milton High School ($14,558), yet Denmark's graduation rate (97.6%) slightly exceeds Cambridge's (97.4%) and its U.S. History proficiency (53%) tops Milton's (43.6%).
While Denmark performs well, it trails its top-tier neighbors like Lambert High School (ranked 10th) and South Forsyth High School (ranked 11th) in Algebra I and Biology proficiency. Denmark's Algebra I scores have been volatile—dipping to 23% in 2023-2024 before recovering to 66.8%—and consistently trail the district average. The school also shows a gap for English Language Learner students, who rank in the 30th percentile statewide. Still, Denmark's overall trajectory is positive: graduation rates hit a five-year high, attendance improved dramatically, and the school maintains strong outcomes despite serving a growing share of students from economically diverse backgrounds (free/reduced lunch rose from 12.4% to 20.5%). For parents seeking a large, comprehensive high school with strong graduation outcomes, effective special education support, and improving attendance, Denmark offers excellent value in a competitive educational landscape.
