or correspondence courses, the student enrolls in coursework delivered outside of normal school instruction. Instruction may be delivered traditionally by mail, but increasingly online courses are used. Effective use of distance learning requires a high degree of independence and motivation. Early graduation from high school or college In early graduation, the student graduates from high school or college in three-and-a-half years or less. Generally, this is accomplished by increasing the amount of coursework undertaken each year in high school or college, but it may also be accomplished through dual/concurrent enrollment or extracurricular and correspondence coursework. In the United States, however, some states do not allow early graduation. Early entrance to college Early entrance to college, sometimes called "early admission", is the practice of allowing high school students to enter 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, and many universities and colleges allow such admissions on a case-by-case basis. However, it is also often done as part of a cohort acceleration program, in which many such students are accelerated into college together at the same time. These programs may provide their students with a social support network and help in dealing with the adjustment. Early entrance programs take a number of forms. Some, like the Advanced Academy of Georgia and The Clarkson School, are special programs within larger colleges. In others, like the Early Entrant Program at Shimer College and the Early Entrance Program at CSULA, early entrants study side-by-side with traditional college students. Bard College at Simon's Rock is a four-year college designed exclusively for early entrants. Early admission to kindergarten In early admission to kindergarten, students enter kindergarten prior to the minimum age for school entry as set by district or state policy. This form of acceleration poses fewer obstacles than others, as places the student in a peer group with whom the student is likely to remain for some time. In many US school districts, early admission requires evaluation, which may include a mock class to test emotional readiness. Early admission to first grade: often occurring where early admission to kindergarten is not permitted. This practice can result from either the skipping of kindergarten, or from accelerating the student from kindergarten in what would be the student's first year of school. This second approach, of skipping kindergarten entirely, is
