The Heldrich Center worked with The Workplace of Southwestern Connecticut to conduct a process evaluation of its U.S. Department of Labor, Office of Disability Employment Policy’s Add Us In grant, which sought to improve the employment outcomes of gay, lesbian, bisexual, and transgender (GLBT) persons with disabilities. Through the grant, The Workplace built partnerships with employers, GLBT-serving organizations, disability-serving organizations, and the workforce system to help GLBT people with disabilities become employed. Through the evaluation, the Heldrich Center generated actionable information on the implementation of the individual project services designed to enable the evaluators to assess the overall effectiveness of Add Us In’s effort to improve vocational services for GLBT persons with disabilities. Specifically, three research questions guided the evaluation: (1) Which of the project services have worked well and which have not been as effective in improving services for GLBT individuals? (2) In what ways can the services be modified during the course of their implementation to maximize their effectiveness? (3) Do Add Us In project services have the intended positive effect on client outcomes (e.g., employment and earnings)?
