The general plan of the 4-year (1966-1970) Educational Laboratory Theatre Project was to have theatre companies in Rhode Island, New Orleans, and Los Angeles give five matinee performances per week for high school students and three evening performances for adults in order to (1) make extensive use of professional theatre as an integral part of school curricula during school hours, (2) provide cultural enrichment to the community at large, and (3) encourage excellence in regional theatre. This first of four volumes of the Project's final report provides a brief history of the Project; information on the reception of the Project in the three sites; reactions of the advisory committee, students, educators, citizens, and theatre companies; summary statements from some of the major figures in the Project; and conclusions and recommendations.
