Police say 30-year-old Aleyda Uceta also bit an officer trying to arrest her after Friday's incident at Roger Williams Middle School in Providence.
She is charged with assault on school officials, assault on police officers and resisting arrest.
Police say Uceta punched Principal Rudolph Moseley Jr. in the face and bit his left arm after he told her that her son would be suspended for three days for refusing to go to a room for misbehaving students.
Attempts to reach Uceta by phone for comment were unsuccessful.
