Our district hires all of our nurses, they don't allow agency nurses. At my school we have 1 student that is 1:1 and we have 2 full time nurses. We change weekly who is with our 1:1 student and who is in the clinic. That way we are both very familiar with the student and it won't matter if one of us calls in sick. It works out well and we've really built a great relationship with the family. Best of luck!
