Most summer psychology jobs come in the form of paid internships as well as clinical research positions for students. In temporary internships, you gain exposure as well as experience that’s essential for advancing in this field and getting your license to practice psychology. In clinical research positions, you usually assist ongoing studies and learn more about various mental health conditions. The exact duration of a summer psychology job varies by employer. Licensed psychologists may also find summer jobs at camps or summer schools, which often involves working with children who have various disabilities, so employers prefer experienced applicants for these positions.
