This article explores, first, the roles that school psychologists theoretic
ally might adopt as change agent: non-change, technician, the social broker
and the social interventionist. Then, we analyse data from a sample of pra
ctising school psychologists to see the extent to which these roles are act
ually manifest in their orientations toward serving as change agent. To ser
ve as successful change agents, though, school psychologists must understan
d the political context, since their stance toward change almost automatica
lly injects them into the political arena. We use examples drawn from the p
olitics of planning literature to note how the role adopted by a change age
nt interacts with political structures to shape the odds of successful chan
ge efforts. Techniques for the school psychologist to learn to better adapt
to political circumstances are outlined.
