ExploreHealthCareers.org has lots of information about a wide variety of careers, including LOTS beyond doctor and nurse—acupuncture practitioner, massage therapist, medical librarian, dental hygienist, environmental health specialist, athletic trainer, . . . even crime scene investigator!
The site also has search feature where you look for careers based on how long you want to be in school and how much money you would like to earn. (It shouldn't be a big surprise that the careers that pay the most often require the most training, e.g., college and medical school.)
If you are a student thinking about possible careers—or if you are a tutor looking for good information to share with your student—this is a great site to explore.
