This is the first in a series of reports on a national study of college students spiritual development currently being conducted at the Higher Education Research Institute. The results are derived from a sample of 3,680 undergraduates attending 46 diverse colleges and universities across the United States. Each student completed a specially designed followup questionnaire in spring 2003 (the junior year in college) in addition to an extensive survey when they first entered college 3 years earlier. Substantial numbers of third-year undergraduates express a strong interest in spiritual matters. More than half place a high value on "integrating spirituality into my life" and more than two-thirds report that they have had a spiritual experience. Three-fourths believe that "we are all spiritual beings." Only 12% said that they did not consider themselves to be on a spiritual quest. In spite of this high degree of personal religious commitment, most students also demonstrate a substantial degree of religious tolerance and acceptance of nonbelievers. About one student in five evidences a high degree of religious and spiritual skepticism, but most students appear to have achieved a relatively high level of "spiritual equanimity." (SLD)
