* Institution: Universities and colleges have different academic calendars. Some use semesters (typically 15-16 weeks), others use quarters (typically 10 weeks), and some use trimesters (roughly 12-14 weeks).
* Program: A program's length depends on the degree or credential it leads to. A certificate program might take one term, while a doctoral degree may take several years (many terms).
* Course Load: A student's course load impacts how many terms it takes to complete a program. A full-time student typically progresses faster than a part-time student.
Therefore, there's no single answer to how long a post-secondary term is. It could be anywhere from 10 to 16 weeks, or even longer in some instances such as summer sessions or intensive courses.
