After first-year students have completed some time at their university, they may find that they did not make the right choice, miss being close to home, or simply want to attend a different institution. When this occurs, they may transfer to another university, usually after their first year. Many other students transfer to four-year institutions after completing an associate degree at a community college. A smaller number of students transfer as part of a dual degree program (such as a 3-2 engineering program).
