For five days, the UK government staunchly defended the controversial algorithm that determined A-level grades before ditching the model because of âsignificant inconsistenciesâ.
On Monday, ministers announced they will allow for results to be based on teachersâ predicted grades for their students, rather than a âstandardisation modelâ that saw the A-level grades of almost 40% of students downgraded from what they had originally been awarded.
It followed criticism from students and headteachers and complaints from dozens of Tory MPs, and came more than a week after the Scottish government was forced into its own U-turn after a backlash about the moderation system used there.
Yet despite the advance notice of the chaos, UK government ministers repeatedly insisted they would not follow the example set in Holyrood, arguing an appeals system would resolve most problems.
The government in England on the eve of the results outlined a âtriple lockâ process: this would allow a pupil to either accept their calculated grade, appeal to receive a valid mock result, or sit a new exam in the autumn.
And ministers didnât appear likely to budge after prime minister Boris Johnson summed up the government line when defending the ârobustâ system. On Thursday, he told reporters that the results were âgoodâ and are âdependable for employersâ.
Speaking on Sky News on the same day, Williamson was clear there would be no volte face.
He was asked by Niall Paterson: âCan you give a cast-iron guarantee, triple-locked if you will, that you will not be forced into an embarrassing U-turn?â
âAbsolutely,â replied Williamson.
That day, the president of the National Union of Students launched a petition against the policy and accused the governmentâs system of being âracist and classistâ.
Larissa Kennedy made the comments on Twitter, writing: âCongrats to those getting results today.
âDue to a classist, racist moderation system, not everyone will receive the grades they deserve.â
The petition claimed the Department for Educationâs âtriple lockâ system amounted to âeducational inequalityâ and was based on a âridiculous algorithmâ which unfairly prejudices students from less advantaged backgrounds.
Dr Michelle Meadows, executive director for strategy, risk and research at Ofqual, responded that there is âno evidence of systematic biasâ in the moderation system.
Still little sign of a U-turn.
On Friday, scrutiny of the impact of the moderation heightened.
With neither the Department of Education or education watchdog Ofqual yet to signal any alteration in the policy, Williamsonâs Whitehall department were moved to post a blog that claimed it had âdebunkedâ misleading claims in the media.
The blog, largely an exercise in semantics, was readily re-tweeted by senior Tories, including by former education secretary Michael Gove. It repeatedly makes a defence of the now ditched âstandardisation modelâ and even suggests it is superior to the âentirely differentâ approach taken in Scotland.
On Saturday, students marched on Westminster and called for the education secretary to be fired. Placard-waving demonstrators chanted âSack Gavin Williamson!â and âTeachers not Tories!â.
On the same day, Williamson gave an interview in The Times where he defended the model once more â and knocked the system deployed north of the border.
âNo U-turn, no change,â he told the paperâs Steven Swinford, adding that âthere arenât any controls, youâve got rampant grade inflationâ in Scotland.
The message was clear: England had done it better than Scotland, and there would be no junking of the algorithm.
Fast forward two days and suddenly there is a very different tone, with the morning briefing to journalists in the Westminster lobby hinting at an imminent big announcement.
By the afternoon, Ofqualâs chairman Roger Taylor, fronting that announcement, admitted the regulator had gone down the âwrong roadâ. And Williamson said he now accepted the model had produced more âsignificant inconsistenciesâ than could be rectified through an appeals process.
Remarkably, the minister claimed the scale of the problem had only become clear over the weekend. âAs we looked in greater detail over Saturday and Sunday, it became evident that further action needed to be taken,â he said, which commentators took as an attempt to blame the regulator for the fiasco.
