The BPS "Arts in Education" policy requires elementary schools to offer at least 90 hours of arts programming for children every year. Each school decides which art classes it wants to offer, choosing from different kinds of dance, music, theater, and visual arts (painting, drawing, pottery, etc.). Children can learn art from different people during the year: their regular classroom teacher, a separate trained arts teacher, artists who visit the school, and arts staff at organizations that sponsor the children on field trips. In addition to the 90 hours each year during the school day, some schools also incorporate art into their after school programs.
