In the United States, high school students apply to four-year colleges and universities, where undergraduate students may earn a bachelor's degree. Others attend community colleges or a two-year institution. These students may acquire a technical degree, a two-year associate degree, and/or prepare for transfer to four-year institutions. Nontraditional students are usually students over the age of 22 who pursue higher education. Students may apply to many institutions using the Common Application. Fees are generally charged for each application but can be waived based on financial need.
