I think jj1968 is still misunderstanding how teacher training works. It's generally 5 days with teachers in & kids not, in the U.K., so tacked on to holidays OR if the staff are really unlucky, 'twilight sessions' after school.
Teachers want to spend the time developing resources & meeting with their departmental colleagues to get their heads round a new GCSE specification, or to reluctantly grapple with a new Whole School Policy that the new Assistant Head is enforcing because they need the data for their MA. Or they'd quite like to get on with clearing out the KS3 book cupboard.
SLT want everyone analysing data.
When stuff like Safeguarding is included, everyone is thinking about a) how best to protect kids AND b) how not to get sued.
External providers come under some scrutiny - no one wants to book anything contentious.
There'll be an awful lot of HTs crossing Mermaids off the list this week. Their credibility is completely blown.
Oddly enough, no one has ever said 'oooh shall we get WPUK in?', because running teacher training sessions isn't any part of what they do.
Feminist organisations aren't being chucked out of schools

Feminists are already in the staff room, thanks.
Peddlers of gender woo, on the other hand, are going to find it a damn sight harder to talk their way in.
