According to The Council for Higher Education Accreditation (CHEA), accreditation consists of “a collegial process of self-review and peer review for improvement of academic quality and public accountability of institutions and programs. This quality review process occurs on a period basis, usually every 3 to 10 years.” 1
Accreditation validates a school’s authenticity and legitimacy, holding it to a particular standard of quality in education. And it sets it apart from those institutions who are not offering those standards. Making sure a school and program you are interested in is accredited isn’t that difficult. More importantly, however, it may save you time and money in the long run when certifying that your prospective institutions and programs are legitimately accredited and accepted by future employers and professional associations.
If you are searching for a graduate school, not only should it be an accredited one, but the graduate programs you are interested in will most likely require that your undergraduate degree was from an accredited school as well.
