District officials will also hold an in-person presentation at Pascack Hills Monday at 7 p.m., at which parents will have an opportunity to ask questions.
The rotating class periods were planned with the aim of balancing out which classes are missed when students attend assemblies or leave early for sports, school officials said last month.
Three days each week, students will have seven 47-minute classes. The other two days, they will have four 85-minute periods.
The new schedule will also give students one "Pascack Period" each week. Students will be able to choose how they spend that period, catching up in areas they are struggling, taking online courses, exercising, or pursuing individual learning interests.
