I'm working to find a solution to the following:

6 to 12 New Hires receive onboarding training over a two-month period
Multiple Trainers input evaluation data over that period of time
Supervisors need access to that data

I've been looking into utilizing Excel with multiple sheets. See the screenshot below for further explanation.

I'm finding youtube videos describing different ways of hiding and restricting tab access but is this is the best way of approaching this problem?

Thanks for your help!
