Re: Is this correct?
Charlie, the point isn't that you know what it means, or even that you gave us that excellent explanation. The point is that the average reader of this phrase won't know what it means. That's why I said it either needs to carry an explanation like yours, or the writer needs to be 100% that the audience who will read this resume is completely familiar with it.
I can write something for an audience who knows a certain term and not explain it, but if what I am writing will be viewed by others, I need to use a different term or explain the term the first time I use it.
If all art teachers know this phrase, and if only art teachers will read the resume, it's okay. But if someone else, like a human resources generalist, will read the resume first, then another way of expressing this must be found.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
