OSTCA is the Oklahoma Speech Theatre Communication Association, an association of college and university faculty promoting speech, theatre, and communications arts education in the state of Oklahoma.

Our purpose is to provide a nonprofit structure that supports the education of Oklahoma speech, theatre, and communications programs; integrates the efforts, interests, and abilities of educators and professionals; and acts as a clearinghouse for state, regional, and national speech, theatre, and communication education programs.

OSTCA has more than 100 members and sponsors at the annual conference each fall. The state conference is open to university and high school faculty and students.
