The initial modelling, undertaken, presumably, without too much time pressure, could not be done without faults creeping in. Thus, there is little prospect that an essentially off-the-cuff response to these flaws will not have some unthought and unsought consequences.
More fires may yet have to be fought by the Government. Further, the backdown has ruled out much of the anticipated $43 million in savings each year over four years thanks to smaller class sizes, which was to have been spent on enhancing teacher quality. With that rationale gone, education groups have fertile ground to suggest there is no point in pursuing the original policy.
They have, of course, not been slow to seize upon this. Their ambition is not simply to prevent bigger class sizes but other initiatives on the Education Minister's agenda. These include the development of a new teacher appraisal system, a requirement for all trainee teachers to have a postgraduate qualification, and, potentially, the introduction of performance pay to recognise and reward teacher excellence.
All these deserve a strong measure of public support. It would be unfortunate, therefore, if the Government were to back off because of one instance of mismanagement.
Indeed, most parents could probably finally be persuaded to accept slightly larger class sizes in exchange for higher-quality teaching if it was clear this would not be detrimental to pupil achievement. This is surely achievable, even though the strident talk of teacher unions will seek to convince the public otherwise.
First, however, the Government must win back public confidence for its policies. Education groups will ensure the case is rigorously tested. But for the sake of parents, their children and the implementation of policies promoting excellence in education, it is important that it is achieved.
