Looking up what they use to teach PHSE in my DC's school and they use Jigsaw PHSE www.jigsawpshe.com
On the website there's a glossary that uses "cisgender" but most of their "LGBTQI+" stuff focuses on gay children from what I've found so far.
Has anyone had any experience of these resources? What's their stance on trans? If the school are using the website, will they be using them for training the staff also?
