Following on from an AIBU were the OP was cross that the teacher didn't appear to have a grasp of basic spelling and grammar, which was followed by some examples of factual errors from teachers, what do you think?
How does that then sit with home educators??
My 2p worth as a parent (and not an "official" home educator but as a parent you do it all the time anyway!) is that I expect teachers to have a really good grasp of literacy and numeracy. If they don't have a wide vocabulary and correct use of language for the children to model, especially when very small, can't see that working. I would include TA and support staff in this too, and this often worries me.
However, particularly with older children of secondary age do you really need to have higher qualifications? Of course secondary teachers usually have a degree in the area that they teach, but is it really necessary? I know that my DD1 in year 12/13 did the AQA bacc which was an extended study, and this was researched at the local uni library etc. She certainly knew more than her teachers in that area- but they (and even I, with no qualification in that field) were able to guide her and direct her use of her own skills to produce an amazing piece of work.
Primary teachers teach all areas. They may have a degree but they teach everything (my DH has a degree in metallurgy LOL) there is an element of teaching things they don't really know but can work round (eg in PE you don't have to be sporty or have sporting interests to teach primary PE etc- you find out what the curriculum is and deliver it- maybe letting kids with a footballing interest explain the offside rule etc). I don't think this matters at all.
Home educators clearly educate in different ways, especially if this is "autonomous" then the role is clearly supporting the child in developing their own interests, but HE kids do GCSEs in subjects their parents aren't specialists and often do very well.
So how qualified do you expect teachers to be... and is society willing to pay them at the appropriate level??
