After graduating from high school, prospective psychologists must earn a bachelors of science in psychology, according to Degree Directory. The website suggests taking classes in statistics, math and learning development as well as in various types of psychology.
Students must also complete a master's degree in psychology, followed by a doctor of psychology (Psy.D.) or Ph.D. The latter entails at least 5 years of graduate study including a research-based dissertation, while the Psy.D. degree is based on examinations and practical work. Students must take classes in research design and experimental methods, according to the Bureau of Labor Statistics.
Raymond Lloyd Richmond, Ph.D., a licensed psychologist in California, advises potential psychologists to become friendly with a psychological research professor while still in undergraduate school and volunteering their services as an assistant. Graduate programs are highly competitive and prefer candidates with research experience. He also recommends applying to many different post-graduate programs because universities are highly selective about their doctoral applicants.
