Classical stage‐based theories of human development, drawn from organismic worldviews, possess many shortcomings when extended to counseling applications. In attempting to reduce development to linear, hierarchical sequences, these theories fail to account for the interactional nature of change processes and implicitly pathologize developmental diversity. Responding to these shortcomings, counselors are turning to contextualist models of development that emphasize process over outcome. In this article I review key assumptions of contextualism, as embodied in social role theory and the life‐span developmental tradition, highlighting relevant theory and research. I propose that two vital forces within current counseling—constructivism and interactional counseling—are animated by contextualist notions of development. Specific implications of contextualism for future counseling research and practice are outlined.
