Then give all your student facing staff iPads and training to start them using them. They are worth it just to ease communication problems.
Research and start consultation , be ready for the battles. We found most onside but some absolutely opposed to using an iPad in school.

Procurement , delivery and insurance all can be competitive in volumes, maybe go with other schools for economy of scale

Get learning how to actually learn with iPads. It isn’t as easy as you would think.
SHARE and SHARE some more. Ideas flow and they need to captured and passed on. Use the students to as digital leaders.
