Not Back To School Camp (NBTSC) is a summer camp founded in 1996 by Grace Llewellyn, the author of The Teenage Liberation Handbook. NBTSC offers support to teenagers age 13 to 18 most of whom are active unschoolers or are pursuing alternative avenues of secondary or higher education. The camp has no religious affiliation. As of 2014, the camp offers about four annual sessions, which are one-to-two weeks long and take place at venues in Oregon, Vermont, and California. Typically, sessions are directed by Llewellyn and attended by about 100 campers plus an eclectic staff who come from all over the U.S., Canada, and other countries.
