i know mine are not as they are years behind due to disabilities and both being failed by school
14 y old is mentally 11-12 and has only just come out of a nervous breakdown caused by y5 teacher(started oct 15 at just turned 11 finished autumn 18 at just turning14 ),he has a range of disabilities(aspergers,moderate autism,GDD(global development delay) by 2-3 years, severe dyspraxia, mild physical tourettes,ODD(Oppositional defiant disorder),severe anxiety and severe sleeping disorder(as in doesn't sleep)agoraphobic for 2 years
8 y old is mentally 4-5 due to disabilities and being left to play for 3 years(reception-y2)as they couldnt be bothered with him and as he was semi verbal he couldn't tell me,i took him out to home educate christmas term 16,he has adhd,asd(moderate),gdd by 3-4 years,pda and spd,cluster speech,semi verbal and separation anxiety(from me)also doesnt sleep
in the last few years no matter what ive tried or done hes still stuck on reception level
tbh i think it depends on the people you mix with,our friendship circles/groups are home ed parents and group meetups and disability parents and groups activities and everyone has a acceptance of what the child can do not what they should be doing and tbh there are some kids 100x worse than mine
