College and university

Post-secondary education in the United States is known as college or university and commonly consists of four years of study at an institution of higher learning. There are 4,352 colleges, universities, and junior colleges in the country.
Like high school, the four undergraduate grades are commonly called freshman, sophomore, junior, and senior years (alternatively called first year, second year, etc.). Students traditionally apply to receive admission into college, with varying difficulties of entrance. Schools differ in their competitiveness and reputation; generally, the most prestigious schools are private, rather than public. Admissions criteria involve the rigor and grades earned in high school courses taken, the students' GPA, class ranking, and standardized test scores (Such as the SAT or the ACT tests). Most colleges also consider more subjective factors such as a commitment to extracurricular activities, a personal essay, and an interview. While numerical factors rarely ever are absolute required values, each college usually has a rough threshold, below which admission is unlikely.

Once admitted, students engage in undergraduate study, which consists of satisfying university and class requirements to achieve a bachelor's degree in a field of concentration known as a major. (Some students enroll in double majors or "minor" in another field of study.) The most common method consists of four years of study leading to a Bachelor of Arts (B.A.), a Bachelor of Science (B.S.), or sometimes another bachelor's degree such as Bachelor of Fine Arts (B.F.A.), Bachelor of Social Work (B.S.W.), Bachelor of Engineering (B.Eng.,) or Bachelor of Philosophy (B.Phil.) Five-Year Professional Architecture programs offer the Bachelor of Architecture Degree (B.Arch.)

Professional degrees such as law, medicine, pharmacy, and dentistry, are offered as graduate study after earning at least three years of undergraduate schooling or after earning a bachelor's degree depending on the program. These professional fields do not require a specific undergraduate major, though medicine, pharmacy, and dentistry have set prerequisite courses that must be taken before enrollment.

Some students choose to attend a community college for two years prior to further study at another college or university. In most states, community colleges are operated either by a division of the state university or by local special districts subject to guidance from a state agency. Community colleges may award Associate of Arts (AA) or Associate of Science (AS) degree after two years.

Some community colleges have automatic enrollment agreements with a local four-year college, where the community college provides the first two years of study and the university provides the remaining years of study, sometimes all on one campus. The community college awards the associate's degree, and the university awards the bachelor's and master's degrees ...
