Art museums around the country host programs for teens every year. Are these programs worthwhile? Four museums around the country conducted a study to determine their effects. More than three hundred past participants, ranging in age from eighteen to thirty-six, were asked to rate their experiences. Three-quarters of respondents said that the arts programs had a more positive impact on their lives than school, neighbors, or family. Two-thirds said that the experience had an effect on their later ideas and actions. According to the study, nearly all of the participants continued to visit art museums, and nearly a third worked in arts-related fields.
