I think what the education system needs are good and committed teachers who are allowed to do their jobs and get a reasonable wage given their working hours.
At the moment, lots of teachers are either leaving or want to leave. They work long hours for relatively low pay, have little status (politically, socially), are often unsupported by the parents in their dealings with the kids, etc. etc. Not a good place to be.
Clearly, there will also be teachers who don't care, who are not good at their job, sure. There are quite a few GPs who don't care, who are not good at their job. However, GPs have a lot of status and a stonking salary, teachers have neither.
What is going on now seems another stab in the back of the teaching profession.
I find it an utter disgrace and really, you are fooling yourself, if you think that this is going to help children.
