Every summer more than 10 million children attend day or resident (sleep-over) camps sponsored by churches, not-for-profit youth agencies, and independent operators. This study explored the outcomes of a 1-week or longer camp experience from the perspective of parents. A national sample of almost 2,300 parents responded to pre-, post-, and follow-up surveys about their children's growth experiences at camp. Parents perceived statistically significant gains from precamp to postcamp in 10 youth development constructs with the highest effect sizes related to adventure/exploration, independence, making friends, positive identity, and peer relationships. Additional gains from the precamp to the 6-month follow-up were noted for leadership. Parents also described what their children learned at camp and what changes they perceived occurred as a result of their child's camp experience. (Contains 7 tables.)
