The initial education that is involved in most health science careers can be daunting, but it is not necessarily the only education that will be required. Once a student graduates and enters into one of the many health science careers available, often professional associations, personal interests, or even the job itself will require the individual to attend school again at some point in the future. This is often done in stages as specialists slowly decide their exact area of study, and qualify for professional certifications and association memberships.
