Teaching is like any job. Some individuals, driven perhaps by an altruistic need to pass on knowledge, strive for excellence while others are content to go through the motions.
This is why I support the Government's plan to create highly paid jobs for the best-performing teachers and principals.
About 6000 teachers will be appointed to expert and lead-teacher roles requiring them to share good ideas across clusters of schools under the plan.
The policy will cost an extra $359million over four years, with the full-year cost rising to more than $150million a year by the end of that period.
It has divided opinion.
Groups representing secondary and primary principals, school trustees, and secondary teachers say the new roles have great potential and would change the way schools work, from competing to sharing best practice.
Others are warning the plan will do little to raise student achievement because it does not address factors that affect students' results, such as societal issues and poverty.
According to a report on National Radio, visiting US education expert David Berliner says outside influences account for about 60 per cent of children's performance, and school factors 20 per cent.
He says it is difficult for principals who have improved one struggling school to repeat their success somewhere else.
In response, Prime Minister John Key says that schemes such as breakfast in schools are helping address underlying causes of poor performance, and education is the best way by far to deal with social problems.
I agree.
Sure, more needs to be done to deal with the wider issues that affect a child's education but the scheme the Government has proposed will reward teaching staff who go that little bit extra for their students.
Organisations that do not reward individuals who strive for excellence on a daily basis are, by default, encouraging mediocrity. The private sector often uses financial rewards to recognise workers who excel at their work.
The same should apply to teachers whose results can be measured by the success of their students.
