This is a really easy-to-mark rubric that breaks it down into marking two parts - their first contact sheet, and their very first darkroom black & white print.
It gives them VERY clear look for's, such as:
-good contract and focus in exposures
-clean film edges (and it gives the reasons why - proper developing time/agitation)
It's for a total /100 which every part really specific - I find they need this for their first print, so they can get very detailed feedback for next time.
Hope it helps!
