After you have an idea of the settings you wish to work and the specialty populations or therapy you wish to apply in practice, you can then find a program that meets your training needs. The program search should be driven by your interests in Psychology and not by a vague or romanticized idea of what a psychologist does. This interest does not need to be absolutely specified before you start graduate school.
Most programs provide some range of training interests.
However, major areas of interest may not be represented in some programs. For example, many programs do not have substantial training in child clinical psychology. If you have an interest in working with children, you will not find the training experiences you need to become proficient in child clinical psychology if you attend such a program. Investigate a large number of programs thoroughly before you apply. After you have a clear idea of the interest areas and specialties that you would like to focus on in training, the next step is to search listings and web resources that describe the programs.
