School Nurse Question- Major involvment in special education programs?

Are school nurses used as a resource person, can they teach health education? :heartbeat
I know that in Chicago Public Schools, if you have your type 75 endorsement (CSN_certified school nurse) you can teach sex ed and so forth. If you do not have the type 75 I believe you can assist a CSN (esentially co-teaching with them) but cannot lead the education.

I didn't do any generalized teaching when I was a school nurse. Would have liked to at times.......!
