I could be all wrong on this, but I work for a major pediatric hospital that contracts with school districts to provide nursing services. My pay is hourly, I am able to get benefits, yada-yada. My base pay is less though than I would be if I was a district employee on the a teacher scale. On the upside of this, there are resources backing you from the hospital. We do also participate in the educational retirement system, not social security. I think there are probably different meanings depending on where you work. I mostly do clinic hands on, but do IHP's and ETR's when necessary.
