I'm afraid to say that in the six schools in which I have for any time taught, I've never come across an ICT teacher with a qualification in the subject....

Well technically it's Computer Science.
nor, for that matter, a school that taught Computing for a qualification
All secondary children have an 'entitlement' to Computing / computer Science at GCSE so all schools should be teaching it (if they can find a teacher).
OP
Tell your dh to give his head a wobble, an 8 year old is hardly likely to be using online banking and tax returns. They are more likely, unfortunately, to come across unsuitable subject matter.
Also if your son has a password for access to a computer, email or whatever, surely as parents you should know what it is?
That would be a big no no for an adult wouldn't it? Shared passwords?
You see this is what teachers do, teach in an age appropriate way and sometimes simplify things for younger pupils. GCSE pupils lear there are OR, AND and NOT gates, they don't learn about NOR and NAND until post GCSE.
I teach 'bubble' sorting, no one actually uses a bubble sort these days but it is a simple sort kids get very easily and is a foundation for other sorts (it's also on the GCSE sylabus).
Think about sex ed, do 8 year olds practice putting condoms on a banana? No.
Do 8 year olds get sex education? Yes.
But contraception is really important I hear you say. It is but not for an 8 year old. Maybe your dh could take in some condoms and a condom demonstrator so she can learn how to put one on properly.
