Many school districts are hard up for substitutes--keep in mind, in the district I sub for, the pay in not that good-$90 for 7 1/2 hr day--the same as a sub teacher. It will at least show you are doing something while you search for another job. Most districts require an RN with BSN for full time-some require school nurse licensure in addition to a BSN. Pay is commensurate with credentials. As a recent grad, I suggest you get experience in an acute care setting (hospital) to master technical skills and assessments.
