Camps provide a substantial opportunity for youth to develop important life skills. Identifying and training staff on critical competencies are essential to achieving the desired outcomes for camp participants. The purpose of this study was to determine the most critical competencies of the 4-H residential camp staff for achieving high staff performance. The modified Delphi technique was used to achieve study objectives. The Delphi panel of this study consisted of 23 4-H camping experts from across the United States. This three-round Delphi study led to identify 15 critical competencies that will be useful in standardizing 4-H camp staff training programs.
