To become a child psychologist, you must first earn a bachelor's degree. Generally, those pursuing this career will major in psychology or a related field. After graduating, you'll then need to pursue a graduate-level degree. A master's or doctoral degree (PhD) in child psychology is typically required to work in the field. To work in your own practice, you will usually be required by licensing regulations to hold a doctorate. Many of these programs require students to complete a supervised internship before earning their degree. Finally, you need to become licensed in your state and become board certified by the American Board of Professional Psychology (ABPP).
