Classroom language: School staff.

To carry on with my first post on class language: https://bit.ly/2KcfUmX, here you have another useful piece of information if you are interested in knowing which is the right name  to refer to each member of the school staff. For some of them, different names are given in US and UK, so I decide to give you both names , and now is up to you to decide which one you prefer to use. 

If you happen to find any error or yo know other ways to name the same member of staff, please make me know. You can add a comment below this post. Thanks in advance.
