Complete your undergraduate studies at an accredited university. You generally need a bachelor's degree before pursuing a master's degree.
Research universities and colleges that have master's programs in fields you are interested in. Browse the internet, but also talk to your professors, colleagues or fellow students from college about possible fits for your master's studies. Check for national accreditation and certification. If a program sounds too good to be true, it probably is. You can't get a master's degree from a legitimate university in two weeks.
Apply to programs that offer financial assistance and opportunities to gain additional experience. Many master's programs offer positions as research or teaching assistants that provide a stipend and valuable work experience. Ask the program about applying for these if possible. Even if money is not involved, the experience is worth it for your resume and future.
Plan a course of study at the university you choose to attend. Talk to a professor or adviser about the required courses and other requirements. Master's degrees generally require a comprehensive examination, either oral, written or both, in addition to a thesis. The thesis is a long written work that shows your research, experimental and scholarly abilities. Some programs offer non-thesis options, depending on your field of study.
Maintain good grades and close contact with your department to ensure timely graduation and fulfillment of requirements for receiving the degree. Master's programs may take anywhere from one to four years, depending on your pace and university requirements.
