There are a few different types of accreditation that psychology programs can receive. The most common and well-recognized type of accreditation is from the American Psychological Association (APA). APA-accredited programs have to meet certain standards in order to be accredited, such as having qualified faculty, offering an appropriate curriculum, and providing adequate resources and facilities. Other less common types of accreditation include state licensing boards and the National Register of Health Service Psychologists. While APA accreditation is generally seen as the gold standard for psychology programs, it's not necessarily the only type of accreditation that matters. Different employers or licensure boards may place different importance on different types of accreditation, so it's important to do your research before choosing a program.
