Inquiry Assessment Idea

I was discussing with my year 6-8 class how we would assess our current inquiry. Based on Muritai's 1-5 system, I gave them some options, eg, 1-5, A B C D, % etc. They all voted for an A B C D rating. Then I asked what an 'A' would look like and they came up with the criteria - they had some great ideas such as, excellent, relevant info and presentation , in depth answers to their wonderings, good evidence of some 'action', referencing etc... We then discussed a D and then filled in the B and C parts. Last time we peer assessed and this time they will self assess along with some feedback from me. We'll see how it goes!!
