North Dakota has always been a large space with a relatively small population. Because of this, rural schools often had a shift in the number of students when children in one family matured and moved on. Then, if a younger family moved into another part of the township, the school often physically shifted to this new location. Staffing was also an issue as a good student/teacher ratio had to be upheld for maximum learning.
On this date in 1915, the school at Halliday was notified that another teacher would be sent out so the school could resume teaching the eighth and ninth grades, which had been curtailed due to a large number of younger students.
Some students had received only an eighth grade education because their school offered nothing higher. It was the school that dropped-out, not the student.
