For example: CSRs/CSR's, RNs/RN's, or As/A's and Bs/B's on a report card, etc.

About 20 years ago we were taught that it was correct to use apostrophes for plurals of capitals (A's and B's) and numbers (80's and 90's), but the convention has changed and so now we don't do it anymore. But we still do it for lowercase letters (mind your p's and q's).

Well if it is a simple plural, then no apostrophe. However if you were referring say to CSR's something or other then there would be. If there were more than one CSR and you were saying the CSRS' blah blah blah, then it takes an apostrophe at the end.
Hope that helps.

No apostrophe for plurals, even abbreviations or years.
e.g. As on report cards, back in the 60s.

The abbreviation for pounds (plural) is lbs.
