JWU's academic year is divided into three trimesters, each 11 weeks long, where the standard fall and spring semesters are replaced with fall, winter, and spring trimesters. With the start of the 2018–2019 academic year, JWU is offering all graduate degree programs, except for the master's-level education programs, on a semester calendar. The conversion to semesters will be completed in fall of 2020 for all undergraduate, continuing education and master's-level education programs offered at the university.[19] Classes are also offered during the summer months, creating a fourth academic period.
