Wifi Lockout?

[specularius]

My local School Board rep knows that I love the android system and asked me a question I can't find an answer to. I have searched but cannot find the answer so thought I would ask here. He wants to supply a 7 inch tablet to all the students in the school district, but wants the ability to lock the tablest so that the Wifi will only connect to the school's Wifi network. Is this a possibilty? Is there an application that will allow the ability to lock the Wifi radio so that it can only connect to one designated hotspot? Thansk for any help anyone can provide.
