I recently toured a new school just days before students began using it and already furniture is being wrongly placed to stop that supervision before it's been used. It's a senior staff office at a critical junction of the school. It's a school that needs to monitor students carefully with staff that stated that they wanted to be able to see more. The Head and senior staff were consulted throughout the design process.
Thankfully the Head has said that the cabinet will be moved and a strict glass policy introduced. (i.e: nothing on or blocking vision panels.) I'm going back in a few weeks time - I really hope that it has been moved. It's always harder later on if a culture of blocking views into classrooms has started.
I'm told it will be moved - I hope it will be! (Watch this space)
