Summary:
Zip code 30238 in Jonesboro, Georgia, is served by a single high school, Mundy's Mill High School, part of the Clayton County School District, which enrolls 1,665 students in grades 9 through 12.
For parents considering this area, Mundy's Mill High School presents a mixed picture. The most encouraging statistic is its graduation rate of 92.5%, which exceeds both the district (86.3%) and state (87.2%) averages, and its dropout rate of 2.8% is only slightly above the state's 2.4%. However, academic proficiency on End of Course tests is a significant concern. In 2025–2026, only 14.1% of students were proficient in Algebra I and 18.9% in Biology, compared to state averages of 48.1% and 47.2%, respectively. U.S. History is a relative bright spot, with 27.8% proficiency, which is above the district's 26.3% but still below the state's 38.5%. The school's state ranking has also declined sharply, falling from the 34th percentile in 2023–2024 to the 18th percentile in 2025–2026.
Two factors likely drive these academic struggles. First, chronic absenteeism is alarmingly high at 34.1%, nearly double the state rate of 17.7%. Second, the school serves an exceptionally high-poverty population, with 99.4% of students qualifying for free or reduced lunch. Notably, per-student spending is $13,498, which is above average, suggesting that financial resources are not the primary constraint. The school's strengths in graduation and retention, combined with its challenges in test scores and attendance, indicate that while students are staying in school, improving daily attendance and instructional support in core subjects will be essential to reversing the downward trend in academic performance.
