2.5.1 Grading rubric - setting pass score

Hi everyone

I'm missing something vital I have assignments set up with rubric marking and students need to get 100% to pass (each line on the rubric only has two alternatives - 0 point (if they didn't achieve that part of the assignment) or 1 point (if they did achieve). Often, there are only 2 or 3 parts to an assignment, so the maximum score is 2 (2 parts) or 3 (3 parts). I have had a couple of trial students get 1/2 and need to resubmit the assignment to cover off the part they didn't achieve. The problem is, after its graded, they're not getting the resubmit option. I don't know where to set the pass grade on each assignment. I know I've set the number of possible resubmissions, but I've missed where to put in the pass mark. Could someone help me with that?
