Related Online Degrees & Career Pathways

Studying Psychology in the USA opens many doors to fulfilling careers, with social work being a popular pathway. Earning an online degree in Psychology or a related field can help you work toward licensure as a social worker or counselor. However, requirements for licensure vary widely across states.

For example, if you’re interested in becoming a social worker in Colorado, you’ll need to complete specific accredited educational requirements, pass exams, and obtain supervised experience.

The process is different for each state. In Connecticut, you should carefully review the Connecticut social work license requirements before applying. Delaware also has its own path to becoming a social worker in Delaware, which includes unique coursework and internship hours.

If you plan to practice in the Southeast, be sure to study the Florida social work license requirements. Each state’s requirements reflect different approaches to training and professional standards, so it’s important to research your options early and choose an online program that meets your state’s guidelines for licensure.
