Some think performance pay for teachers would improve quality, but it's a flawed concept that this country would struggle to implement well.
Why? Because who knows how to measure teachers' performance? There are too many variables, not least of which is student ability.
Yes, there need to be checks and balances when it comes to our children's education - it's too important for there not to be - but teacher performance can't be easily measured by revenue, sales, turnover and the like as it can in other jobs.
As in other industries, performance pay does exist in one small form - good teachers looking to step up can earn positions of responsibility where available.
But this isn't what some in Wellington have in mind. Treasury Secretary Gabriel Makhlouf was reported in March as saying raising teacher quality was "the single biggest issue the country needs to tackle to raise living standards".
That's putting an awful lot of responsibilities on schools.
You'd have to ask - where do parents fit in the grand scheme of things?
By all means find a way to improve teacher quality and make sure poor teaching is addressed. But as the Government has learned - don't dare do it by bulking up our kids' classrooms.
