I'd contact the California School Nurse Assocation http://www.csno.org/ for details re: educational preparation and continuing education. I got a job in school nursing at a school nursing conference. Volunteering during screenings is anotehr way to make contacts.
Actually there are several school nurse positions listed in California NurseWeek:
1) Alhambra School District- $53,420/yr
2) Downey Unified School District- $4,291/mon
3) Placer Union High School- $22-$49/hr
4) Stockton Unified School district-
I assume School nurses are paid well here in California because of the strict educational requirements. Also, because of the recent school shootings, many schools districts are looking to expand on their school nurse programs in response to the problem. Some states are using some of the tabacco settle ment money to fund these programs.
Everything varies. I work for the school district as a school nurse under a nurse who is certified as a school nurse. I am an R.N. and have a lot of autonomy. You have to be lucky and know some people. Good luck!
