 Most programs are members of the National Association of Therapeutic Schools and Programs (NATSAP); several have additional affiliations, such as the National Association of Therapeutic Wilderness Camping.The Aspen Education Group in 2005 was the target of criticism related to the large revenues its programs generated, and the charge that the provider takes advantage of parents in desperate situations.The Group has been closing programs since then, citing the difficulty in keeping enrollment numbers up, such as when the Oakley School announced on its website in May 2017 that it would be closing.
