The gap between those with the most advantage/ disadvantage will become more polarised.
Background factors affecting educational outcomes have long been recognised. Maternal education, access to books, ethnicity (cultures valuing education and the typical education level of immigrant communities), cultural capital and experiences, physical resources (particularly access to computers, printers, internet) but also pens, art supplies, space, parental time. It's not as simple as a middle/ working class split, but those factors do have class features to them.
Knowing DS1's class, I reckon I could pick 3 out of the 5 children most likely to slip further behind, and those who will keep ahead. DS1 himself has multiple high functioning SNs, "fortunately" he already has his own computer for school work due to his literacy difficulties leaving the other avaliable for DS2. While he is not a self motivated learner in a traditional sense, he is curious and banks up an encyclopeadic general knowledge. He has the benefit at present of a 1:2 ratio, plus I'm a SAHM with a decade of teaching experience. My primary concern is getting him settled back into a varied social world on the other side of this. While we might not be rapidly ploughing through the school tasks set, I can revise some of those troublesome basics while DS2 is works through them (and push DS2 with some of DS1's work), and there's plenty of enrichment such as Lego, the sandpit, walking in nearby countryside on our daily exercise and documentaries to keep their brains stimulated.
Sadly I can predict who in the class will be spending much of their time playing (several years underage) with unrestricted time on Fortnite, that co-incides with the habitually late and the parents that won't consent to trips to places like the Gurdwara and never sighted at any school events.
