Hi Mommyand RN,
Subbing is definitely a good way to get your foot in the door of school nursing.
Now I want to qualify that by saying that it is good to be available whenever you get that call. It will go against you if you are called and you refuse multiple times. You will find that the calls will taper off and then you will stop getting them altogether.
Good luck in whatever path you choose !
