ChrisMayLA6, In a letter to the Guardian Toby Wood raises an interesting point:
Is the profit/surplus-driven model of education (the Academy model) worsening the problems of retaining teachers & the thrusting of teaching assistants into their role(s)?
This may be a single case but its not implausible that it represents a wider trend.
Another case of the ideology of markets corrupting & damaging a vital public service?
