Research evidence of this type in school counseling is difficult to find for several reasons.
The outcomes of school counseling are somewhat less easily defined and measureable
than those of other professions. Few rigorous, large-scale studies of the benefits of
school counseling have been conducted, although these studies have typically found that
school counseling is very beneficial to students (see Lapan, Gysbers, & Sun, 1997; Sink,
Akos, Turnbull & Mvududu, 2008; Sink & Stroh, 2003). Good research is expensive and
unfortunately few foundations or federal agencies have been interested in supporting
research in school counseling.
