I am French and I was a school nurse during 3 yrs in France. There are school nurses in my country
they practice in elementary, middle, high and colleges. The scope of practice is similar as the US' school nurses : health programs (nutrition, addiction, sexuality, birth control...) follow up (vision, hearing,...), providing urgent care, assistance for chronic illness kids, conseling students, families, etc..
I forgot a difference : in France only RN can practice in schools
, there is no school nurse aid.
Hope I answered your question.
