I'm just wondering if your child's primary school does netball as a PE subject and/or a PE as an extra curricular club.
My DD's school doesn't do any netball as part of PE for any year group. They run a netball club for Y5 and Y6, which my DD1 got to take advantage of but now DD2 has reached Y5 the girls have to try out for the team and are then invited to come along to the club, by letter, if they are successful.
There has been very poor provision for sport overall in the school, so it's rather disappointing to get to Year 5 and find the door is closed to DD2 accessing any extra curricular sports in school. I just wondered how common it is to not do netball in PE and to run extra curricular sports in this exclusive way.
