Yes, in California you have to be an RN with a bachelor's (does NOT have to be in nursing) plus extra classes/certification to be a "School Nurse." You can however, be a nurse (RN/LVN) that works for the school district without this certification. It may not pay has well as a "School Nurse" but considering you have ALOT of time off and everyday your children have off, it's a wonderful job. For extra money in the summer you can work as a camp nurse, making up to $1000 a week, plus your kids can usually come with you! Or you could work prn too during the school breaks.
There are school district jobs open for LVN's in California. Some of them are listed as Health Tech II, and some are open as LVN's, other school districts call them instructional aides. LVN's are responsible for tube feedings, trach care, cauterization, colostomy care and diabetes management. Here is an article about replacing Health Clerks in the TUSD with LVN's.

As a cost cutting strategy, school district are following the same model as Tehachapi of 1 RN for the entire school district and LVN's doing all the care and treatments for the students. With the controversy of on an RN/LVN being the only people able to give insulin, more schools are hiring LVN's. But some school districts have cut costs even more by hiring lay personnel off the street and task training them to everything an RN/LVN does
, which has prompted the CA BON intervening with the injunction prohibiting insulin to be given by lay people.
Google the Los Angeles School District and do a search for LVN. Here is just one LVN job description but the position is called Instructional Aide (LVN) Instructional Aide (LVN) cc4552
There are others out there. You may also do some tutoring/teaching in your down time between students.
Also check with private agencies. I was once recruited to be a one on one aid by a staffing agency for a 3 year child so he could attend preschool.
Good luck, it's a fun job!
