Based on the premise that a multischool theatre festival can provide educational interaction on a noncompetitive basis, this guide has been prepared as an aid for schools and theatre arts departments wishing to host such a festival. The guide discusses a variety of theatre festival components, including (1) the purpose and types of festivals; (2) host sites; (3) designing the festival; (4) publicity; (5) evaluation; (6) festival models--theatrefest, drama festival, play clinic, and workshop; (7) scheduling; (8) commentators and workshop presenters; (9) registration fees; (10) accommodations; (11) invitations; (12) information and registration packets; (13) staff; (14) food; (15) final preparations; and (16) festival participants' evaluation.
