Psychology's knowledge is fundamental to the preparation of professionals i
n human service settings, and psychology informs practice applications to t
he design of community services. This article provides examples of the conc
eptual developmental process in 4 applications of psychology to education-i

ion professionals, and in consultation to education professionals. These ex
amples support 3 general propositions for promoting psychology's educationa
l applications. First, the student or professional, not the professor or th
e supervising psychologist, generates applications derived from the array o
f problems identified. Then theory-based arguments are used to develop new
perspectives. Second, the professor of psychology or the supervising psycho
logist after providing opportunities to acquire knowledge tools, creates ta
sks designed to develop and evaluate applications to problems. Third applic
ations of psychological knowledge reflect conceptual change, which is evide
nt ill the descriptions of the ways psychological knowledge is used and mod
