What makes a competent psychologist?

In developing European standards for the psychological profession, two main approaches to the definition of professional competence have been proposed. One focuses on the roles and functions psychologists should be able to perform (output model), the other on the educational curricula that should be followed in order to become a psychologist (input model). This article starts with a discussion of both approaches, which leads to the conclusion that neither of them offers a sufficient base for setting adequate professional standards. Next a comprehensive model of occupational competence is presented which comprises both input and output factors. It is indicated how this model can. be utilized in defining competence profiles for the psychological specialties, as well as in developing and maintaining competence. Issues covered include: student selection, academic curriculum design, initial professional training, continued professional training, institutional and individual.accreditation, and quality assurance.
