This article describes how people adapt to new roles by experimenting with
provisional selves that serve as trials for possible but not yet fully elab
orated professional identities. Qualitative data collected from professiona
ls in transition to more senior roles reveal that adaptation involves three
basic tasks: (1) observing role models to identify potential identities, (
2) experimenting with provisional selves, and (3) evaluating experiments ag
ainst internal standards and external feedback. Choices within tasks are gu
ided by an evolving repertory that includes images about the kind of profes
sional one might become and the styles, skills, attitudes, and routines ava
ilable to the person for constructing those identities. A conceptual framew
ork is proposed in which individual and situational factors influence adapt
ation behaviors indirectly by shaping the repertory of possibilities that g
uides self-construction.
