I remember someone on another thread describing it as the young, inexperienced pilots in WW 1, ‘Aces high’ who flew and got shot down relatively quickly. Yes we are running out of young well trained staff, who are cheap. Too many schools chasing the same cannon fodder and too few schools willing to employ experienced older teachers. Not enough work available in supply to make real living at it and unscrupulous agencies taking too much of a cut. Using your analogy johnjcazoria, yes we have reached the tipping point and like global warming there is an unwillingness to change things in education. Assuming we do not reach a catastrophic situation someone eventually is going have take the lead and put education back on the right track. We cannot have a generation of benefits street, the country cannot afford this to happen. If this happens then we truly have become a third world country.
