 Class rank is more likely to be used at large schools that are more formulaic in their admissions programs.Some U.S. states guarantee that students who achieve a high enough class rank at their high school will be admitted into a state university, in a practice known as "percent plans".Students in California who are in the top nine percent of their graduating class, and students in Florida who are in the top twenty percent of their graduating class are guaranteed admission to some state school, but not necessarily any particular institution.
