Sharing rubrics on schoology?

Hello everyone!
I am a teacher for LAUSD. I am teaching AP CSP for the first time ( by that I mean I didn’t pilot it last year). I am not very familiar with schoology so what I decided earlier in the semester was to go in the direction of google classrooms. Unfortunately, I was successful implementing nor did I get any support.
Anyways, the main reason I am sharing my thoughts in this blog is because I am confused about the rubric provided on some of the documents available to our students in code.studio.org. Correct me If I am wrong. But when I first noticed the rubrics on some of those documents, I thought the rubric was there to help students (guide their conversations / thoughts) write down more clear protocols. Some of my students have communicated that they thought I was going to use it to grade their protocols.
How are you using them?
