This survey report relates and analyzes the results of an exhaustive survey study of the status of theater in U.S. high schools. The report is divided into six sections. Part 1 is a general description or "snapshot" of the status of educational theater. Part 2 takes a look at the people who teach theater. Part 3 is an examination of theater in the high school classroom. Part 4 describes production facilities and activities. Part 5 employs an analysis of the survey findings to define and identify effective theater programs. Part 6 compares these 1991 findings with the findings of Joseph L. Peluso's 1970 study of the same subject. In addition, the report contains a section on how the survey was conducted and two short articles: "Laying the Foundation for a New School Theater" (Kent Seidel); and "Finding the Keys to Good School Theatre: Some Comments on the ETA Survey" (Burnet M. Hobgood). The report indicates the following results: (1) almost 90% of American high schools offer their students some kind of theater activity; (2) principals generally have a high opinion of the value of theater for students in classes and shows, but are less aware of the value for other students and for the school's standing in the community; (3) well over half of the theater teachers in U.S. high schools hold advanced degrees; and (4) students involved in educational theater tend to be disproportionately white and are rated as affluent. Fourteen figures are included. (PRA)
