Which charities/outfits are the ones that provide poor materials for teachers to use?

[KleineDracheKokosnuss]

I’m trying to find a secondary school for DC1. I want to ask whether they use materials written by Mermaids etc, but I can’t Remember who the other ones who provide materials unmoored from reality and usually contrary to D of E guidance are. Can anyone remind me?

Safe Schools Alliance or Transgender Trend would probably have the info on their sites.

Here you are - it's free to download from Transgender Trend and covers many of the groups giving dodgy "advice" & resources to schools:

Thanks!
