The decisions you make about where to apply and what type of program to pursue are monumental. Graduate programs consist of advanced study of a particular discipline in the natural or social sciences, humanities, arts, etc., and can prepare you for a variety of careers.
Professional programs involve training for a specific profession.
This can be found in a school's program description. Graduate programs at the Masters level vary from 1 to 3 years and a Ph.D. can range from 4 to 7 years. Conducting informational interviews in the fields of your interest can be a valuable way to discover if a program is for you. Spend plenty of time discussing options and concerns with your academic and career advisors too. Consult with your professors and the Career Development Center.
