Summary:
Heidelberg High School is the only high school in zip code 39439, serving grades 9–12 in Heidelberg, Mississippi, with 246 students and a 100% free/reduced lunch rate, operating within the East Jasper School District.
Since only one school is in this area, its performance also represents the district’s results. Heidelberg High School stands out for strong Algebra I scores, beating state averages in both reported years (78.1% proficient vs. 66% in 2025–2026, and 87.2% vs. 67.3% the prior year). Chronic absenteeism is also a bright spot at just 10.0%, well below the state’s 23.9%, despite the school’s high poverty level. The graduation rate of 87.5% is close to the state average of 89.2%. However, the school’s Biology proficiency collapsed from 57.1% in 2024–2025 to just 15.0% in 2025–2026, while the state stayed near 63%. That dramatic drop is the most urgent issue in the data. English II remains below the state average, improving slightly from 39.6% to 42.8% but still trailing the state’s 49.3%.
Heidelberg’s state ranking has slipped from 115th (3 stars) in 2023–2024 to 137th (2 stars) in 2025–2026, though it did improve from 148th the previous year. The school sits in the middle of the state distribution, but performance is uneven: excellent math and attendance contrast with weak science and moderate English results. Because the school and district figures are identical, Heidelberg is effectively the only high school in the district, meaning any changes at the school directly shape district outcomes. Families should view Heidelberg as a school with strong student persistence and math achievement, but should also ask about the Biology decline and literacy support. The school’s 2-star rating reflects a mix of strengths and concerns, with Algebra I and attendance offering a solid foundation for improvement.
