The use of children and adults as “practice” subjects in psychological testing courses raises practical and ethical concerns. Surveys examined how instructors of beginning child and adult testing courses handled these concerns. Instructors relied primarily on classmates and nonclient volunteers as practice subjects, but nearly one-third also included testing of child or adult clients. Recruitment, consent, supervision, feedback, and data handling procedures were examined. Ethical problems reported most frequently involved feedback, competency and preparation of students, and access to appropriate practice subjects. These findings guide recommendations for protecting the rights and well-being of individuals who contribute to training efforts.
