Attendance zone
Zones are set by Gwinnett County Public Schools and do not follow city limits. Check any address with Find My School, or see the district’s Meadowcreek Cluster map (PDF). In the analysis behind our neighborhoods guide, which matched Gwinnett County’s address points inside Duluth to the district’s 2026 zone map, no address in the city is zoned for Radloff; it serves homes with Duluth mailing addresses south of the city, around I-85.
Ferguson Elementary feeds Radloff, and Radloff students go on to Meadowcreek High, according to the district’s 2026 zone map data. Students in the Meadowcreek Cluster can also choose McClure Health Science High, according to McClure’s registration page. The district’s Meadowcreek Cluster page lists every school in the cluster.
We found no rezoning approved by the Board of Education that changes this zone. Gwinnett County Public Schools paused its multi-year redistricting plan effective Sept. 23, 2026, said it will not redraw attendance boundaries for the 2027-28 school year, and plans community conversations in the second semester; our schools guide has the details.
The school’s website is subtitled “Readiness, Respect, and Responsibility” and has a page telling Louise Radloff’s story.
