The objective of the study is to examine the factors of a successful diversity program within four companies that attempt to break down the barriers contributing to the lack of diversity within the design and technical field of theatre. Companies in different regions of the United States (West, Midwest, South, and Northeast) were selected and analyzed for their fellowship, apprenticeship, internship, and educational program in order to see why it is successful and how it contributes to diversifying the design and technical field of theatre. The findings of the study provide a guide to the best practices used in establishing a design and production program that can contribute to diversifying the theatre industry.
