Limited empirical data on the roles associated with boards of directors in nonprofit organizations are available, yet understanding the work of boards is vital to ensure the roles desired by organizational members and the roles required by the organization are being fulfilled. The roles or functions of boards in nonprofit organizations, as found in the management literature, were used to explore the roles associated with a sample of nonprofit amateur sport organizations. Data were generated from a survey of executive directors, volunteer presidents, and volunteer board members of sport organizations housed at Ontario's Provincial Sport Centre in Toronto. The survey data yielded a 4-factor subscale providing support for a theoretical perspective in assessing roles of the board in mission, planning, executive director, and community relations areas. Similarities and differences of respondents by gender and position on ratings of importance and performance for the board roles were explored with implications for board development discussed.
