Abstract This study surveyed the selection practices of group leaders. The study explored methods of selection, variables used to make selection decisions, and the types of selection errors that leaders have experienced. The results suggest that group leaders use clinical judgment to make selection decisions and endorse using some specific variables in selection, and that selection errors can have a detrimental effect on the selected member, the group, and the leader. Suggestions on ways that these selection errors might have been prevented are also reported.
