I found an answer and I'll post it for someone else who may have the same question. I'm sure most on this board have been professionally trained, and in that case my question is probably moot, but for those self training like myself, I think the question is valid.
The best place for both training material and calibration charts is DSC Labs
Welcome to DSC Labs
They have an excellent student book which is available through B&H Photo:
dsc labs imaging technology dsedu | B&H Photo Video
The Title is: DSC Labs DSEDU Imaging Technology: An Advanced Guide to Digital, Film & Television Production
This gives a great overview of both the charts and how/why to use them.
