A middle school in Ohio has a novel take on the Senior Prom.

For years, spring at Troy Intermediate School in Avon Lake, Ohio has meant the Senior Prom, a dance party for sixth-graders and their grandparents.

I read about the tradition in a recent story in the city’s local paper. The party—which, unlike most proms, calls for casual attire—is jointly organized by a social studies teacher and the local PTA.

This year’s event featured hotdogs, a DJ, a photo booth, and games. About 80 students attended with their guests. Kids who don’t have a grandparent in the area can bring another “special senior.”
