A summer session is shorter than a regular semester and not considered part of the academic year. It is not the third term of an institution operating on a trimester system or the fourth term of an institution operating on a quarter calendar system. The institution may have 2 or more sessions occurring in the summer months. Some schools, such as vocational and beauty schools, have year-round classes with no separate summer session.
