Hmm, not sure. There are so many reasons people dislike MG that there's perhaps a tendency to blame him for things that aren't his fault whilst overlooking his successes.
I'm not an Education professional so bow to the expertise of those who are. But MG was EdSec 15 years ago and during those 15 intervening years so many other factors have been at play, many of which have been harmful to children and childhood.
Gove's drive to improve standards was egalitarian at heart. There are young people in really hard-pressed urban areas receiving an education that would have been unthinkable 20 years ago- the 62 Oxbridge places won at London Academy of Excellence for example. Breaking the grip of Local Authorities over schools, introduction of Free Schools etc created opportunities to do Education differently, and clearly some good has come from that. And wasn't it Gove who created Teach First? Getting brilliant new graduates to consider teaching and putting them in the most challenged inner city schools was impactful, wasn't it?
As an adopted child himself, he did great work improving the adoption system so more children would benefit from loving and supportive adoptive families, as he had.
MG had a keen sense that he had benefitted from certain opportunities that some of his more traditionally-privileged Cabinet colleagues took for granted. He wanted to make these available to all children, and central to this was the idea that the better outcomes achieved by independent and grammar schools are created by rigour. He saw the mainstream state provision as lacking rigour and essentially being lazy and complacent, so that educational attainment was determined by chance rather than policy. Mathematics is probably the prime example of this, but another would be his enthusiasm for Latin as an academic subject.
I don't have experience of SEND and can't claim any expertise on this. But I do think there's a general trend towards diagnosis for any problems in life, and I don't think Gove can be responsible for that. Social media and digital tech has shortened attention spans and I can see that this could be an uncomfortable fit with Goveian rigour.
I've always been conflicted about Michael Gove. I worked for him in a different Govt department and found him receptive to advice and respectful of expertise. He was immensely courteous (which made a nice change). He exhibited levels of liberalism in penal policy that only a Tory right-winger could get away with and stands out in my mind as one of the most humane Justice Secretaries I've known. He also had some attitudes that were alarming and within the course of a single day I could think both 'I would walk over hot coals for you' and 'I hope the PM sacks you today'. He had a hatred of Theresa May when she was Home Sec, that played out in the politics of the two Departments, which was both childish and destructive. What I really can't forgive him for is providing the political and intellectual veneer of respectability for the Brexit campaign, without which I don't believe Leave would have won the Referendum.
Michael Gove was a conviction politician of the Right with a genuine drive to change public services for what he believed would be better. We currently have a conviction politician of the Left with what I have to assume is a genuine drive to change public services for what she believes will be better. Unfortunately politics are a pendulum whereas professonal policy development generally inhabits centre ground. I've yet to see a determined reform programme in any Government department that is welcomed and supported by its practitioners. Dept of Health over decades illustrates this. Actually, in Justice, Gove came closer than most.
He has acquired a sort of pantomime villain persona in the public consciousness that underplays what a consequential figure he has been. If the Brexit Referendum hadn't come along, with all that followed, we might have seen Gove become a great Home Secretary or Foreign Secretary and today he'd be Chancellor of Oxford University instead of William Hague.
