I think it is poor, to be honest, but am cynically resigned to the fact that too many HTs are basically concerned about budgets rather than what is best for children's education.
The primary my DCs attended was a small village one - HT 'taught' Y6. In effect the TA 'taught' Y6 as HT was always somewhere else. TA was surly and resentful and clearly hated being left teaching all day on a pittance of a salary. She was snappy and unpleasant to the pupils. I went in several times to complain, but nothing happened and we resigned ourselves to the fact that we would have to live with it. We didn't want to pull the children out and send them to a new school 6 months before they went up to secondary.
In my present school (secondary) we have unqualified TAs working as 'Cover Supervisors' as they are clearly much cheaper than getting in qualified supply teachers. (I understand they get something like £1.50 per hour extra if they 'teach' a cover lesson). They are covering up to GCSE classes - and basically say to the kids 'this is the work' and put it up on the board. They then sit there whilst the kids chat, mess about and do no work whatsoever. The pupils know they are not a 'proper' teacher and the TAs have no training in behaviour management, nor to be frank, the ability/power to implement it.
We also have 3 TAs working as 'Instructors'. None of these ladies have any qualification to do so. One has 2 A levels (in unrelated subjects). The other two only have up to GCSE qualifications. They are 'teaching' a timetable of around 18 lessons a week, mostly at KS3, but one has 3 GCSE classes of lower ability pupils. If these were my DCs I would be kicking up hell, frankly, but I suspect parents are unaware that 'Miss Smith' who teaches History has no qualifications to do so. Parents are not informed of teachers' qualifications or suitability for the role - they presumably assume that their child's teacher is qualified. This is not always the case. Academies can employ unqualified staff, certainly. There is some vague statement about 'anyone the HT considers suitably qualified' to allow this.

Whilst many people will come on saying, 'I am an HLTA and I am a qualified teacher, etc' please be aware that I have never personally come across a qualified teacher working as a TA in 20 plus years of teaching. I am sure it does happen, for many reasons - either it fits in with their families, or they cannot find a teaching post. But I can honestly say that in our rural area the TAs tend to be very nice ladies in their 40s and 50s who certainly do not have formal qualifications of this level. I do not know any who have gone on to train as teachers from the route of HLTA/CS. This is (presumably) because they would need to take time out from work to do 2 years 'A' levels, 3 years Degree (with the associated financial costs) plus 1 years teacher training. It is a subject that makes me furious.
Look at any school and the new teachers they take on - I do not know of any locally who have employed anyone other than an NQT in the last few years. Because a 22 yo straight out of training is a hell of a lot cheaper than a teacher in their 40s who knows what they are doing. I have colleagues who have applied for jobs, gone to interview, and been gutted that, despite having 25 years experience and 'Outstanding' Ofsted observations they have been rejected in favour of someone just leaving a PGCE. You would not go for a job as a Consultant Surgeon and find yourself competing against someone who had just left Medical School and be told that 'they answered the interview questions really well'... They might well have done - but I know who I would prefer to be operating on me. Experience (which is expensive) counts for very little in schools now. If your school suddenly has a new 'teacher' of 45 I would be cynically wondering what grade on the pay scale they were, frankly. And whether they had QTS or were an 'Instructor'.
I think it is a massive betrayal of our children.
