The authors point to what they consider to be four crises in education:
"a 40-year ideological experiment in marketisation and neoconservatism."
"teacher recruitment and retention are in a downward spiral."
"the glaring lack of a... curricular policy to teach about climate change"
"the ways in which Covid has increased educational inequalities"
It seems a bit like an odd selection, somewhat specific to the U.K. context, yet not completely so - I see similar issues, for example, in the United States and Australia. I think they're also based in a specific philosophy of education, one that sees it not only as a public good, but also as an instrument for projecting public policy. Not saying any of this is wrong, but I don't think people outside the system would see the issues in exactly the same way.
