National's aims are noble, we all want to keep the best possible people leading our schools and teaching our children, but it's hard to go past the widespread acceptance that smaller classes are better for both teachers and students in terms of lifting achievement.
And shouldn't our schools by now already identify and nurture talented teachers and have good quality-control systems? If not, why not?
Both Labour and National have plans to take good teachers out of the classroom to work with other schools and teachers.
While the aims behind this may also be noble, as a parent I struggle with the concept of taking the best teachers away from their classrooms.
Would you want your child's top-performing teacher seconded out to another school?
It may sound selfish to want good teachers to stay put (and, to be fair, it could be your kid's teacher benefiting from the extra help) but when it comes to our children I, like most parents, reserve the right to be a little selfish.
