hide or show sheets that I created

You mean to have certain teachers see certain report sheets? You can't filter that way at this point.

I just wish they could hide some that the instructor will not use

Do you have a Hide/Unhide option on the report sheet deployment page? Like:

That is, you can hide them from everyone at this point.

Not what I wanted.
I guess my question it must be in blueprints.

Well, we file things like this as bugs. I'm thinking about using blueprints more, but for brainstorming bigger sets of functionality. Could you just describe it as a bug?

Do you just want *teachers* to be able to hide irrelevant report sheets?

Yes, I have 3 different ways of rating for 3 school levels: Kindergarten, Primary and Secondary and 3 scoring systems (A, B, C --- AD, A, B, C --- 1 to 20)
The only way I found to use schooltool is creating 3 scorecards to each teacher's use according to the level of the section, the other should be able to hide them.

For this reason I requested 2 or 3 reportcard: https://answers.launchpad.net/schooltool/+question/254816

Thanks Tom Hoffman, that solved my question.
