Sensible governors will not be taken in by the Education Secretary's exhortations that echo football club directors who sack their managers. It does not work in football and it will not work in schools.
In an ideal world, all football managers would be as talented as Ars ne Wenger and Sven Goran Eriksson. In an ideal world, all heads would be superlative and, if they were not, parachuting in a "super head" would solve all the problems.
But we live in the real world - and we know there is a normal distribution of ability among heads and that the commando-style importation of super heads just does not work.
We should not tolerate incompetence - because it is the children who suffer. But the majority of heads range from competent to good to excellent. These heads will perform better in an atmosphere of trust and where their governors offer them both support and challenge.
That trusting relationship must be fostered and worked at - and Mr Clarke's suggestion that governors should be "ruthless" in "taking out" underperforming heads is unhelpful.
