What is the different between Gross and Net Enrollment rates (GERs and NERs)?

Question

Quizplus · Accepted Answer

The Net Enrollment Rate (NER) specifically considers the official school-age population for a given level of education, thus taking into account students' age, which helps in understanding the proportion of students in the appropriate age group that are enrolled in school. This contrasts with the Gross Enrollment Rate (GER), which includes all students enrolled at a level of education, regardless of age, and can therefore include students who are older or younger than the typical age for that level.
