this investigation dealt with the problem student actors confront in making a transition from educational to professional theater due to inadequate or insufficient training. A mail survey was conducted with 110 Equity stock theaters to determine whether or not those theaters serve an internship function to offer additional training and assist the beginning actor in his transition period. The introduction considers professional attitudes toward educational theater and the subsequent need for internship. The second and third chapters discuss the construction of the mailed questionnaires and the more significant responses. The last chapter concludes from the 57.3 per cent response that Equity stock theaters constitute an important but limited source for the student actor to learn and practice the arts of the theater.
