Related Online Degrees & Career Pathways

Earning an online degree in psychology can lead to various rewarding career paths, including roles such as counselor, clinical psychologist, school psychologist, and licensed professional counselor (LPC). However, pursuing a career in mental health involves more than just obtaining a degree—there are specific education, practicum, and state licensing requirements that must be met.

If you’re considering becoming a licensed therapist, it’s important to be aware that requirements can differ significantly by location. For example, explore the Boise licensed therapist education requirements to understand what is necessary in Idaho, or review the Boston licensed therapist education requirements to see how Massachusetts approaches licensure. Similarly, New York candidates should be familiar with the Buffalo licensed therapist requirements, while those in Arizona can review the process for becoming a licensed therapist in Chandler.

No matter where you plan to practice, researching state-specific regulations—alongside choosing a strong online psychology program—can help you take the right steps toward a successful career in mental health.
