How to remove MDM from iPad iOS 9.1
Open general, swipe up on the right side, find Profiles &amp; Device Management and tap it.

Tap each of the profiles in turn and delete them. The MDM profile should show "Remove Management" in red and explain what it will do. The others should say "Delete Profile"

When that's done, you should have a clean device that you could erase all content and settings. Then see that the device isn't tied to a corporate Device Enrollment system. In that case, you'd want to return the iPad or get a bill of sale indicating that the device will be released from "corporate" control in a period of time.

The DEP can be under education or business - so the steps they take will be similar to release that serial number and not re-enroll it in the MDM each time the device is configured/activated.
