Abstract Based on a survey of boards of non-profit organizations in India, this paper examines the extent to board effectiveness is influenced by board inputs, structures and processes. The findings provide mixed support for the normative literature on board effectiveness. Using stepwise logistic regression the research suggests that board inputs and three process variables are important in explaining board effectiveness, namely: board members have the time, skills and experience to do the job; clear board roles and responsibilities; the board and management share a common vision of how to achieve their goals; and the board and management periodically review how they work together.
