Lots of good advice about creating an environment that is welcoming and safe. One concern I have is the idea that teachers must never leave students unsupervised- while I completely understand the liability and duty of care at play in this, some teachers have multiple workspaces or labs/shops where it is impossible to have your eyes on students at all times. This puts teachers in a difficult position and leaves students in potentially unsafe environments. I believe it is the duty of the administrator to address this, and it is a concern that I have seen in several different schools.
