A view of one of the Freshmen tables on the second day of school.
Freshmen are students which are currently in the ninth grade of post-kindergarten school. This year of school is often called 'the Freshman year'.
One of the Freshman tables on the third day of school.
North Shore High School does teach freshmen students. On the map Janis Ian made of the lunch room tables, it shows that the freshmen take-up only two tables in the cafeteria.
None of the freshmen students play any major role in Mean Girls or Mean Girls 2.
