Cornwall has three elementary schools, all educating students from kindergarten through fourth grade. The former Cornwall on Hudson main school building, on NY 218 in the center of the village, is now Cornwall-on-Hudson Elementary School. Cornwall's school, located on Willow Avenue outside downtown Cornwall near the hamlet of Firthcliffe, is now Willow Avenue Elementary School after educating sixth and seventh graders for the later 20th century. A third school, known formally as Cornwall Elementary School, is referred to within the district as Lee Road Elementary School for the street it is located on. It was built in 1968 due west of what is now Cornwall Central Middle School, located along Main Street just south of Route 218 outside the village.
