I don't think the schools are worried so much about not knowing how to teach students to use a word processor, but rather their IT staff not being able to maintain the equipment and set things up properly.

The poor admin that has to deal with all the lost machine and device enrollment, and password resets and OS upgrades borking stuff, they are the ones who schools are optimizing for.
