If your career of choice requires additional education, you'll be going to graduate school. Some people decide to go directly into graduate school after college, while others wait a couple of years. Once you decide that you are ready to go to graduate school, make sure to give yourself the time to research the schools you're interested in, apply for admission, take the required entrance exams, and get your financial aid in place.
If you have student loans, find out if they can be deferred if you go on to graduate school. Also, be sure that your undergraduate credits will transfer to the graduate school you're thinking of attending. Talk with your academic advisor about this issue.
You may be thinking you have to attend graduate school full-time, as you are doing with your undergraduate degree. For some programs, this will be the best—and possibly only-approach. However, if you're pursuing a master's degree in business, fine arts, education, or other field, you can attend graduate school part time while you're working, either full time or less than full time.
Many universities have graduate programs set up specifically for working adults. Classes meet in the evenings and on weekends, and courses are often taught by professionals in the industry, so you're gaining real-world experience from someone who lives what he or she teach.
In addition, your new employer may even pay for your advanced degree, or at least part of it, through tuition reimbursement. With most tuition reimbursement programs, generally your graduate school studies must apply directly to the position for which you were hired.
This is a great way to earn an advanced degree without footing the entire bill. Even better, you'll often be able to take the knowledge you're learning in class right back to your job. It's frequently a win-win situation for you and your employer.
