Oddly, teacher unions continue to press for lower ratios as the fashion in education becomes team teaching of larger classes. Innovative schools are knocking out walls, doing away with individual desks and letting pupils move around as they wish, to learn with whom they wish, at the pace they prefer, while a number of teachers hover to help.
That probably sounds much worse to most parents than an organised class of 25-28 with one teacher responsible for it. But Education Minister Hekia Parata appears to have endorsed team teaching with enthusiasm. It provides an answer to the practical problem posed by the Government's lead teacher proposal.
The scheme would involve taking a good teacher out of a school for two days a week and having him or her work in other schools nearby.
The plan is still under discussion with the unions and other interests. So far, secondary teachers are more amenable than primary teachers. Secondary classes are accustomed to different teachers in the course of a day. But primary schools are the trial ground for team teaching, which ought to make them more open to the Government's proposal.
While Labour wants to divert the money to the training of more teachers, it is having a bob each way. Its policy includes raising the entry standard for training and setting up a system for selected teachers and principals to help other schools. Education spokesman Chris Hipkins said it wants to provide teachers with an additional career path, as though this is as important as bringing better teaching to more pupils.
Labour subscribes to the unions' dogma that every trained teacher is as good as the next and all that pupils need is more of them so that classes can be smaller. National says that is not so. A child's progress depends much more on the quality of teacher than the number in the class. That may be so but Labour has the simpler line to sell.
