I can provide some general information on the topic.
In the real world, licensing requirements for clinical psychologists vary by country, state, or jurisdiction. The process typically involves completing specific educational requirements, obtaining supervised experience, and passing licensing examinations.
In the United States, most states require a doctoral degree in psychology from an institution accredited by the American Psychological Association (APA) or another recognized accrediting body. Walden University is indeed accredited by the Higher Learning Commission (HLC), but it's not accredited by the APA. As a result, graduates of non-accredited programs like Walden University may face limitations in obtaining licensure in some states.
However, it's important to check the specific licensing requirements of the state or country in which one intends to practice, as regulations can change over time, and there may be alternative pathways to licensure for individuals who have graduated from non-accredited programs. Additionally, some individuals who hold a doctorate in psychology from a non-accredited institution may still find opportunities to work in related fields or pursue different careers outside of licensed clinical practice.
