As influential as spirituality might be, it is an aspect of human life that has not been well researched as such. Related aspects of religion and values have been researched a great deal, and these studies help counselors understand the probable effects of spirituality. The probable impact of spirituality on school counseling is not yet a subject of concerted study. Spirituality provides an opportunity for collaboration between school counselors and students around student diversity and development. North America in general and counseling in particular are now emerging from the limitations of worldviews that led to avoidance of spiritual topics. Spirituality, religion, and values, of course, are not synonymous. They overlap. Spirituality contains numerous values and religion is one expression of spirituality. The biggest restriction of school counselor-student collaboration is the counselor's belief that a restriction exists. Given that spirituality is too big of an issue to ignore, it is important to address the phenomenon cogently and systematically. The purposes of this article are fourfold. First, spirituality in general is considered. Second is a summary of various notions of spirituality and worldviews. Third, the place of spirituality as an aspect of diversity and development is examined. Fourth is a discussion of the practical implications for school counselors.
