Summary

Miller Grove High School in Lithonia, GA, is a large public high school serving 1,073 students in grades 9-12 within the DeKalb County School District, where 100% of students qualify for free or reduced lunch.

Miller Grove is a school on the move. After several years ranked in the bottom quarter of Georgia high schools, it jumped to the 31st percentile (2 stars) for the 2025-2026 school year—a significant improvement from the 21st percentile the year before. This upward trend is backed by real academic gains: Algebra I proficiency more than doubled from 14.6% to 33.4% between 2023-2024 and 2024-2025, and U.S. History proficiency jumped from 24% to 36% in the same period. While current proficiency rates in Algebra I (32.1%), Biology (30.9%), and U.S. History (25.1%) still trail state averages, the momentum suggests recent interventions are working. One standout: the school ranks in the 54th percentile (3 stars) for its African American students, placing it in the top half of schools statewide for that group—far above its overall rank.

The biggest challenge is attendance. Chronic absenteeism sits at 43.9%, more than double the state average (17.7%) and well above nearby Stephenson High School (29.2%) and Arabia Mountain High School (15.3%). The dropout rate of 4.6% is also nearly double the state average, though it's a marked improvement from 7.7% two years ago. However, there's a bright spot: the graduation rate of 83.5% exceeds the district average (81.4%) and has climbed from 76.5% in 2020-2021. With a favorable student-teacher ratio of 14.9 and per-student spending of $19,071, the school has resources to build on its gains. Compared to peers, Miller Grove outperforms Towers High School and Martin Luther King Jr. High School (both 22nd percentile) but trails Stephenson (55th) and Arabia Mountain (61st). The path forward is clear: improve daily attendance and sustain recent academic progress.
