As a behavioral intervention specialist, your job is to help create and implement a treatment plan to manage the mental health of your client. In this role, you may conduct a psychological assessment of each patient, use ongoing testing to monitor their progress, and put them under observation to determine what other care they may need. As an interventionist, you are most likely going to work with children from a variety of situations and backgrounds, including children with complex medical conditions or history in a troubled household. Being able to identify the causes of problematic behavior and adjusting your responses to account for these is essential to this job.
