The field of special education recognizes the need to foster self-dete
rmination among students with disabilities; here we argue that support
for self-determination must begin long before students leave schools
to assume adult responsibilities of work, independent living, and comm
unity participation. We begin by describing developmental investigatio
ns of metacognition, self-perception, social problem solving, and auto
nomous decision making. Because development occurs within the context
of interpersonal relationships, we discuss critical attributes of the
social environment that must be considered if efforts to support self-
determination are to be successful. Our examination of the development
al underpinnings of self-determination leads us to conclude that atten
tion must shift to (a) supporting basic research on the emergence of s
elf-determined behaviors in young children; (b) promoting policies tha
t draw attention to elementary and middle school contributions to self
-sufficiency; and (c) ameliorating aspects of the curricular instructi
onal, and service delivery systems that foster dependence, while expan
ding students' opportunities to exercise choice and engage in self-enh
ancing independence.
