Rubrics are deceptive. They seem like a good way to let all the teachers in your team know how to mark students' work. Unfortunately, although they appear to be objective, they usually leave much open to interpretation.
That means that the team will still have to meet and discuss what the criteria apply to actual work, and generate a shared understanding of what the boxes mean. They will also need to generate examples of work that meet the various criteria, for themselves, future colleagues and, of course, the students themselves.
