Can SKY Add-ins be created for School K12 environments?

Rick Baer

I have been unable to find documentation on "Add-in Extension Points" for School K12 environments.  Do they exist and can a SKY Add-in be created for K12?  If so, could someone point me to the documentation.  If they do not exist, is there a plan to offer Add-ins for K12 and is there a schedule for when they would be available?  Or perhaps is there some other way to do Add-ins for K12 schools?

Thanks.
