The River Valley Community School District operates public schools serving the community. It was established on July 1, 1996 by the merger of the Eastwood Community School District and the Willow Community School District.
Quimby once had its own school district, its mascot known as the "Quimby Peacocks" but financial pressure and dwindling enrollment forced the school to combine with nearby Washta school district to create Willow Community School District, the mascot being the T-Birds. In the early nineties the same factors led to the merger of Willow and nearby Eastwood School district to form River Valley School District, with the mascot of the Wolverines. The new district encompasses the towns of Quimby, Washta, Cushing, and Correctionville. Although it is the second-largest,[which?] Quimby does not house a portion of the school's classes.
Quimby maintained a school building, which housed the River Valley Middle School classes until the building, which was constructed in 1921, became too expensive to keep up to code. The building was sold to a local resident, Tim Tapper who held the property for several years before selling it to a private developer who demolished the building.
Quimby boasts a nine-hole golf course, a rarity for towns in the area of relative size.
