Related Online Degrees & Career Pathways

Considering a career in healthcare doesn’t always mean becoming a physician. There are a variety of related fields and online degrees that provide rewarding opportunities in the medical sector. For example, many students with a bachelor’s degree in a non-nursing field are looking at direct entry msn programs for non-nurses online, which offer a fast-track into advanced nursing roles.

Ease of entry is a concern for many applicants. Exploring easiest nursing programs to get into can help bypass some of the intense competition seen at top medical schools. Similarly, for those interested in healthcare administration or insurance, medical coding and billing classes online with financial aid offer practical, in-demand skills from the comfort of home.

Admission requirements can also be a hurdle for some aspiring healthcare professionals. Fortunately, there are absn programs that don't require teas or similar standardized exams, opening doors for more students. Each of these pathways can lead to a fulfilling career in the growing healthcare industry.
