Related Online Degrees & Career Pathways

Studying Psychology in the USA can open doors to a range of rewarding careers, including social work. Many students consider online degrees to fit learning into their busy schedules. It's important to understand the education requirements for specific fields and states before you commit to a pathway.

For instance, the social worker education requirements in Illinois specify that aspiring social workers must earn at least a bachelor’s degree in social work (BSW) for entry-level roles, with higher-level positions requiring a master’s degree. Similarly, the Indiana education requirements for social workers mandate a BSW for basic licensure, while clinical practice calls for advanced study.

States like Iowa also set well-defined benchmarks; the Iowa minimum degree requirement for social workers is a BSW, but those wishing to provide clinical services need a master’s degree. Meanwhile, the social worker education requirements in Kansas highlight both bachelor’s and master’s qualifications for various levels of social work licensure.

Choosing a Psychology program—especially an online option—should align with your career goals and the state-specific requirements for your desired profession.
