Original Research by School Decision on Martin Luther King- Jr. High School
Martin Luther King Jr. High School is a public high school serving grades 9–12 in Lithonia, located in eastern DeKalb County on the Atlanta metro fringe. The school enrolls a mid-sized student body, drawn almost entirely from the immediate area and overwhelmingly from families who qualify for free or reduced-price lunch. The student population is predominantly Black or African American.
Academic performance shows a sharp divide across subjects. State proficiency data from the most recent testing cycle shows the school performing at high levels in English language arts, science, and social studies. Mathematics proficiency, however, is substantially lower. Because only one year of state testing data is available, no trend can be established; a parent may want to look into this further with the school, particularly what the school is doing to address the mathematics gap and whether additional support is available for students in that area.
The school is part of DeKalb County School District, which is currently in the middle of a significant multi-year restructuring. The Student Assignment Project, launched in 2024, aims to close or consolidate dozens of underutilized schools over the next several years to address empty capacity across the district. An initial scenario flagged more than two dozen schools for possible closure; revised cluster-specific scenarios have followed, with a final recommendation to the Board of Education expected in December 2026. Any family considering this school should be aware that attendance boundaries and school assignments across several clusters—including the Druid Hills cluster—may shift as the project moves forward. This is not a near-term or speculative concern; it is an active, multi-year planning process that could affect where a student attends school or where a family decides to live.
In addition, the district has funded a slate of capital projects through E-SPLOST VI, a one-cent sales tax approved by voters in 2021 and running through mid-2027. Those projects include new and rebuilt schools and the creation of specialized academies in performing arts, cyber technology, and career and technical education. While Martin Luther King Jr. High School itself is not listed among the major facility projects, the broader reshaping of program offerings and school assignments across DeKalb will touch the ecosystem in which this school operates.
Property taxes in DeKalb have been a significant cost factor for homeowners. The district's millage rate, historically among the highest in Georgia, has been reduced for three consecutive years, but because property values in the area have risen, the actual tax bills on homes have continued to climb. Housing values in the Lithonia zip code are below the state average, and rents are moderate relative to income. The area is growing, with new residential subdivisions and townhome communities under construction nearby, and transit-oriented development around the I-20 corridor is being studied as a longer-term growth opportunity.
Lithonia itself is a small city rooted in its granite-quarrying past, with a walkable historic downtown and a tight-knit community. Schools serving the city are located outside the historic core; the school sits in the broader Stonecrest corridor, which has emerged as one of DeKalb's faster-growing areas. A parent choosing this school should do so with eyes on both its current academic strengths and weaknesses and the district's ongoing structural changes, which will reshape school assignments and offerings over the next few years.
