Summer Sessions

Some universities in the United States offer classes during the summer break between May and August. The school may offer one or two "summer sessions," and each session usually lasts between six and ten weeks.

Many universities open summer session classes to the outside public, and they sometimes make available on-campus dormitory accommodations. You may find that students who are enrolled in a degree program at the university also take classes during the summer in order to finish their degree faster than usual or to catch up on classes they missed or in which they want to improve their grades.

While summer sessions at U.S. universities offer degree-level courses, summer schools and similar programs offer a broad range of courses structured for personal enrichment and professional development. Such programs can be found at certain English language centers, as well as at institutes offering classes in cooking, diving, fashion, music, the arts, and other topics.
