The Preschool Program

The Thorne School offers two morning preschool programs, one for 3-year-olds and one for 4-year-olds. Although the Thorne Preschool is designed for typically developing children, children with special needs can be considered for admission if their needs can be met in the regular classroom.

The morning program begins at 9 a.m. and concludes by noon. Children may arrive as early as 8:30 a.m. and must be picked up by noon. Morning programs are five days per week.

"At each stage of Thorne school I have watched my daughter become more skilled at navigating social situations. She knows how to share, she knows how to stand up for herself, she knows how to play with old and new friends." —Preschool Parent

Thorne School also offers an afternoon program for children from both the younger and older morning classes. This mixed-age group class is similar in structure to the morning program but includes a lunch, rest time, and a special activity (music, science, art, movement). The afternoon program concludes at 3:15 p.m. and is offered two, three, or five days per week. Children staying for the afternoon must provide their own lunch.
