The Nampa School District is converting high school class schedules from two semesters containing eight classes each, to three trimesters with six classes apiece.

But the new schedule cuts the equivalent of nearly two weeks of instructional time from each class over the year. The administration says they were aware of this sharp cut.

The new schedules will be six classes long — students will take the same six classes each day — and be switched three times over the course of a school year, for a total of 18 classes per year.
