Look into different education programs. The Princeton Review and US News both have thorough online databases, including rankings of the best schools. If you know what you want to specialize in, such as administration or art, then use this opportunity to select an appropriate program.
Apply to the schools you're interested in. Every school has a unique application, but common features include personal essays and letters of recommendation. If you have experience teaching, then be sure to get a letter from your school's principal.
Finance your tuition. If you've saved up enough money, you can pay out-of-pocket. Otherwise, consider taking out loans through the FAFSA. Supplement this with grants and scholarships from private foundations. You can research scholarships by perusing the databases on Fastweb and SchoolSoup.
Attend graduate school. Every program has its own coursework and expectations, but in the majority of programs you'll spend your time researching and writing essays, as well as guest teaching in nearby schools.
Complete your thesis. In most graduate programs, your thesis will be the culmination of your research, measuring forty or more pages in length. Once your coursework and thesis have been approved, you'll get your Master's in Education.
