Psychological clinical science has made enormous progress both in terms of scientific contributions and as a source of continued development for improving how psychologists are trained for the future. At this crucial juncture, we see not only great challenges but also great opportunities, not the least of which is rethinking and expanding how internship training could be conceptualized within clinical science training. As ongoing changes in the health-care delivery system impel psychological clinical scientists to continue the process of redefining themselves as a field, so have those changes brought into relief the limitations of the traditional internship model. Redefinition and reconceptualization are in order, and this article is intended to encourage and facilitate that process. Three of the authors are currently directors of clinical science internships and the fourth previously served in that role. As we articulate later, we see an opportunity for internship experiences to integrate more seamlessly with graduate training by providing unique training opportunities associated with expanded clinical science career trajectories and identifying proximal and distal measures of training and career success.Among the core goals for clinical science training is the effective integration of science and clinical practice. However, although the clinical science model has done a commendable job of defining and measuring key standards for scientific training (with well-articulated outcomes measures that allow program directors to meet identified training goals in a flexible way), the model has yet to fully meet the challenge of defining, measuring, and incentivizing key clinical practice standards. We propose that the assessment of clinical competence within the clinical science model requires an appreciation for
