Intern Experience

There is a wealth of training opportunities at D6 for interns including, but not limited to, individual and group psychotherapy, psychological and neuropsychological assessment, functional behavioral assessment, behavior support plan development and implementation, consultation, crisis intervention, and professional development. As part of the internship experience, interns provide psychological services at an elementary school, middle, or high school. 

Additionally, supervisors work collaboratively with interns to provide opportunities to meet their individual training needs and goals, which are agreed to at the beginning of internship and adjusted as needed throughout the year.  This may include working with specialized programs (intensive autism, affective behavior, deaf and hard of hearing, and life skills); district teams (BrainSTEPS, crisis intervention, juvenile corrections, preschool, and transition 18-21); professional development; and supervision. We strive to support our interns as they progress in their development and become more independent in their competencies.
