Is the school you want to attend accredited?
"The goal of accreditation is to ensure that education provided by institutions of higher education meets acceptable levels of quality. Accrediting agencies, which are private educational associations of regional or national scope, develop evaluation criteria and conduct peer evaluations to assess whether or not those criteria are met. Institutions and/or programs that request an agency's evaluation and that meet an agency's criteria are then "accredited" by that agency."
For more information on accreditation in the United States, please visit: http://www.ed.gov/admins/finaid/accred/index.html.
There are a number of accrediting institutions, some are listed below.
