Step-by-step explanation:
The correct order of professions in the field of mental health, starting from the highest level of education required, is: 1) Psychiatrist, 2) Psychologist, 3) Therapist, 4) Psychiatric Technician. Psychiatrists are medical doctors with a specialization in mental health and are able to prescribe medication, which requires earning a Doctor of Medicine (MD) degree. Psychologists usually hold a doctoral degree, either a PhD or PsyD, and are trained to administer and interpret psychological tests, but do not prescribe medication. Therapists can have a range of qualifications from a master's degree to a doctoral degree, depending on their practice area. Psychiatric Technicians typically do not require education beyond an associate's degree or certification.
