I am currently working in an educational institution that has Office 365 ProPlus available to its students.  Students install Office 365 themselves via the Office 365 portal, and settings are administrated through the Admin Center.

The instructors at my institution are concerned about Office 2016 rolling out mid-semester.  Currently the textbooks and accompanying simulation software is based on Office 2013 and will not be compatible with a new version.  The classes will not be moving to Office 2016-based curriculum until Fall 2016.  There was an understanding that updates could be disabled for one year through the Admin Center, but I'm uncertain how this might be possible with the Admin Center settings.

Will it be possible to prevent deployment of Office 2016 until the curriculum is prepared for it?  We are trying to plan for the looming change.
