The Ph.D. degree culminates in a dissertation based on original research. Courses in quantitative research methods, which include the use of computer-based analysis, are an integral part of graduate study and are necessary to complete the dissertation. The Psy.D. may be based on practical work and examinations rather than a dissertation. In clinical or counseling psychology, the requirements for the doctoral degree usually include at least a 1-year internship. Competition for admission into graduate programs is keen.
Some universities require an undergraduate major in psychology.
Others prefer only course work in basic psychology with courses in the biological, physical, and social sciences, statistics, and mathematics. The National Council for Accreditation of Teacher Education, with the assistance of the National Association of School Psychologists, also is involved in the accreditation of advanced degree programs in school psychology. The APA also accredits institutions that provide internships for doctoral students in school, clinical, and counseling psychology. Psychologists in independent practice or those who offer any type of patient care, including clinical, counseling, and school psychologists, must meet certification or licensing requirements in all States and the District of Columbia. Licensing laws vary by State and by type of position.
