According to the US Dept of Labor:
A bachelor’s degree in psychology qualifies a person to assist psychologists and other professionals in community mental health centers, vocational rehabilitation offices, and correctional programs. Bachelor’s degree holders may work as research or administrative assistants for psychologists. Some work as technicians in related fields, such as marketing research. Many find employment in other areas, such as sales or business management.
In the Federal Government, candidates having at least 24 semester hours in psychology and one course in statistics qualify for entry-level positions. However, competition for these jobs is keen because this is one of the few areas in which one can work as a psychologist without an advanced degree.
*Most specialists, including clinical and counseling psychologists, need a doctoral degree; school psychologists need an educational specialist degree, and industrial-organizational psychologists need a master’s degree.
*Competition for admission to graduate psychology programs is keen.
*Overall employment of psychologists is expected to grow faster than the average for all occupations through 2014.
FYI: Training for a Psychologist:
A doctoral degree usually is required for employment as an independent licensed clinical or counseling psychologist. Psychologists with a Ph.D. qualify for a wide range of teaching, research, clinical, and counseling positions in universities, health care services, elementary and secondary schools, private industry, and government. Psychologists with a Doctor of Psychology (Psy.D.) degree usually work in clinical positions or in private practices, but they also sometime teach, conduct research, or carry out administrative responsibilities.
A doctoral degree generally requires 5 to 7 years of graduate study. The Ph.D. degree culminates in a dissertation based on original research. In clinical or counseling psychology, the requirements for the doctoral degree include at least a 1-year internship.
What could you do with a masters in psychology?
Persons with a master’s degree in psychology may work as industrial-organizational psychologists. They also may work as psychological assistants under the supervision of doctoral-level psychologists and may conduct research or psychological evaluations. A master’s degree in psychology requires at least 2 years of full-time graduate study. Requirements usually include practical experience in an applied setting and a master’s thesis based on an original research project.
What is it and what does it take to become a psychiatrist?
Psychiatrists are the primary caregivers in the area of mental health. They assess and treat mental illnesses through a combination of psychotherapy, psychoanalysis, hospitalization, and medication.
Formal education and training requirements for physicians are among the most demanding of any occupation—4 years of undergraduate school, 4 years of medical school, and 3 to 8 years of internship and residency, depending on the specialty selected. A few medical schools offer combined undergraduate and medical school programs that last 6 rather than the customary 8 years.
What is a psychologist?
Clinical psychologists—who constitute the largest specialty—work most often in counseling centers, independent or group practices, hospitals, or clinics. They help mentally and emotionally disturbed clients adjust to life and may assist medical and surgical patients in dealing with illnesses or injuries.
Counseling psychologists use various techniques, including interviewing and testing, to advise people on how to deal with problems of everyday living. They work in settings such as university counseling centers, hospitals, and individual or group practices.
