Re my dismissive "bunch of randoms" comment 😁. In terms of access to specific mental and physical health data linked to children as they grow into adulthood, these people are a bunch of randoms. They have no right to access such immensely confidential personal information. They're not the NHS, medics or even educators. What legitimate reasons do they have to access and monitor a 13 year old's views and full physical and mental health history into adulthood?
If I've understood this correctly, it's a money making enterprise for the organisations involved. They're inappropriately pushing a contested ideology at children. They're promoting their view of "wellbeing" and trying to find data to support this. They'll no doubt write or commission one of their favoured organisations to produce materials to be sold to schools. They'll sell the confidential data they've accessed to others. And so on.
I'm not a data person (evidently) but am sceptical about on what authority this business is harvesting children's data and who will benefit from it in the long run? As TT have pointed out they're not bothered about accuracy of the data (see @Szygy's post at 12:49). They make claims about schools and wellbeing that lack evidence but could of course financially benefit them.
Just because an organisation dresses up their aims and financial opportunities in the language of rights and insights, doesn't actually mean that what they're doing will be of any benefit to society as opposed to lining their own pockets.
