I just recently found out how our local district operates regarding textbooks and thought it sounded crazy, but now that I see how it's becoming more the norm, I realize our district doesn't sound so bad. About three weeks before the start of school our district has an orientation camp where all students are able to tour, ask questions, and pick up all their textbooks. This set of textbooks received at orientation stays at home. Each teacher has a full class set of whatever book from which they teach in the classroom, and these never leave the classroom.
I heard the decision was implemented a few years ago because of kids having to lug around several heavy backpacks and to reduce/eliminate the number of kids coming to class unprepared and without their books.
