Early entrance to college, sometimes called early admission or early enrollment, is the practice of allowing high school students to be accelerated into college, one or more years before the traditional age of college entrance, and without obtaining a high school diploma. In some cases this is done individually. Often, however, it is done as part of a cohort acceleration program, in which many such students are accelerated into college together at the same time. These programs are usually targeted to gifted students, and may provide their students with a social support network and help in dealing with the adjustment.
