How to Enable iPad multi-user support?

You would need to purchase the iPad Classroom deployment software, which is only available to education institutions. That feature is not available outside of the Apple Education deployment program at this time.

For home users or any iPad other than one enrolled in an education deployment plan, the device remains a single user, single account device.

This sort of feature may make it into wider spread use - who knows what Apple may or may not change in future iOS releases? For now, it is a feature explicitly available for schools, especially where they may not be able to afford one device for every student. My understanding is that the feature relies on the deployment server to cache user(s) settings, profiles and content, so relies on more hardware and administrator expertise than any typical home user is going to have available. It does not offer multiple user accounts simultaneously on any individual iPad. Instead, it uses "smart" user cache and some sort of system to push out user profiles as needed.

It sounds to me like it involved much more in terms of the deployment system, and far less with iOS on the device itself.

Thanks for the question :

I have the same question too and was planning to buy the last iPad Pro ...

Given the Apple's answer I won't buy it !

It's always good to see someone who does their research and doesn't spend ~$1000 on a device that doesn't meet their needs.
