Summary:
Hanahan, South Carolina is served by a single public high school, Hanahan High, which enrolls 1,061 students across grades 9-12 and is part of the Berkeley 01 school district.
For parents considering Hanahan High, the most encouraging news is its remarkable upward trajectory. The school has jumped from the 49th percentile statewide in 2023-2024 to the 75th percentile in 2025-2026, earning a 4-star rating and ranking 61st out of 245 schools. This improvement is driven by genuine academic strengths: English 1 proficiency sits at 75.6% (nearly 15 points above the state average), English 2 proficiency is 85.6%, and U.S. History proficiency is 71.0%—all above district and state averages. The school also boasts a very low dropout rate of 0.9%, less than half the state average of 2.1%, and a graduation rate of 89.0% that exceeds both the district (86.2%) and state (86.7%).
However, there are two significant concerns. First, Algebra 1 proficiency collapsed from 67.2% in 2024-2025 to just 31.0% in 2025-2026—a drop of over 36 points that leaves the school far behind the district (46.2%) and state (64.6%). This appears to be an isolated issue, as all other subjects improved or held steady, but it warrants immediate attention. Second, chronic absenteeism is notably high at 27.2%, compared to 23.9% for the district and 22.3% for the state. Despite this, students remain enrolled and graduate at strong rates, suggesting the school has effective retention strategies. With per-student spending of $14,018 and a student-teacher ratio of 16.5:1, Hanahan High is delivering strong results in most subjects, though the math decline suggests resources may need to be redirected to support Algebra 1 instruction.
