What is the difference between 202110, 202150 and 202180?
Spring, summer and fall semesters are denoted by the codes 10, 50, and 80, respectively. For example, 202110 denotes Spring 2021, 202150 Summer 2021 and 202180 Fall 2021. The number refers to the month in which classes for that term begin (August is the eighth month, and so on).
Unless you are specifically looking for data about spring or summer, the standard term for reporting is fall.
