The fear causing so many to leave their classrooms and attend stopwork meetings is the possibility that principals and boards might decide they can make do with fewer teachers if they organise all their educational resources for possibly better results. It is a possibility not a probability.
Schools that already have this flexibility, private schools and charter schools, do not replace teachers with machines. They value small class sizes above almost everything, as do parents.
But it is doubtful that every school needs the same ratio of teachers to pupils. There ought to be room for each school to decide how to spend its budget for best value. The present Government has been more determined than most to tag its funding of all social services for measurable results. It has published a set of specific targets to concentrate the minds of providers at all levels on concrete improvements.
To this end Parata and her officials are also reviewing the much-criticised "decile funding" for social disadvantage. They believe the information they now collect from schools enables them to direct those funds much more precisely to individual needs rather than rely on district statistics from the census.
This week schools were told how much they are likely to receive on the new basis. While those in well-off "decile 10" areas will receive even less under "at risk" funding, they cannot complain. Decile funding has been an inefficient device for getting additional funds to those who need them.
Efficiency should not stop there. Global budgets sound capable of producing better value for the taxpayers' outlay and should not be abandoned because teachers fear their jobs would be less secure.
