A Child Study Team (CST) is a group of three professionals who evaluate children for special education services. The basic CST consists of a school psychologist, a learning disabilities/teacher-consultant, school social worker, and (for preschool students) a speech-language specialist.
CST members also provide ongoing services for students after educational classifications are designated. As a student's case manager individual CST members are responsible for overseeing their educational program.
School psychologists provide direct support and interventions to students, consult with teachers, families, and other school-employed mental health professionals (i.e., school counselors, school social workers) to improve support strategies, work with school administrators to improve school-wide practices and policies, and collaborate with community providers to coordinate needed services. https://www.nasponline.org/about-school-psychology/who-are-school-psychologists
