Research the job market to determine which field of study you intend to pursue. If you have a certain vocational field you plan to pursue, determine which academic majors are needed to work in those fields. The Bureau of Labor Statistics website has the most comprehensive listing of career fields and job descriptions, including the necessary education to pursue a degree in that field.
Consult magazines like "U.S. News & World Report" and other websites that provide rankings of college degree programs. Online Education Database, for example, provides a listing of top-rated online colleges. It also has a separate listing for nursing schools. Knowing which schools in your intended field of study are the best, may play a role in determining where you choose to attend school.
Visit the website of your state's department of education or board of regents for higher education. Do this also for any other state where you think you may attending school. Some states provide an online database of all of the college college degree programs offered in their state. The board of regents in the state of Oklahoma, for instance, has a listing of all academic degree programs offered in the state. Other states like Pennsylvania, Texas and California also have similar options to search for colleges by major.
Search for degree programs by visiting the website of colleges you have a specific interest in attending. These may be schools that you found while researching top programs through publications like "U.S. News & World Report" or they may be schools that you have interested in for other reasons like location or financial aid. Most colleges and universities provide a way to search for degree programs either through an internal website search engine or by browsing the different academic programs.
