Horrifying but unsurprising. Maybe this will finally get some traction.
On a similar note - It doesn't mention primary schools in this report much but sexist attitudes and roles aren't challenged early and become harder to break later.
Every year, I watch girls organise, care for and chivvy their male peers while staff tell them to care for others etc. The expectation always falls on the girls to care for the hapless and useless boys. The reinforcement of the roles of women in caring roles and arts subjects starts early.
It doesn't help that the staff usually model these roles: men in leadership roles or they are based in scientific areas of the school while most art subject teachers are female.
We also always have to be aware of covering stories with male central characters to 'interest the boys' so girls get exposed constantly to stories of daring, heroic boys. The emphasis is seemingly never on showing a range of daring, heroic girls.
I know these sound small - most of the outright gender stereotypes are challenged but the underlying attitudes of the roles of girls are allowed to fly under the radar until they become entrenched.
