Ian Leckie, immediate-past president of the New Zealand Education Institute, says compiling data by region is "just nonsense" and results in "useless data" being released.
He says no one has a clue whether the information is accurate or not, because every school has its own way of providing the information.
In response, the Ministry of Education says the information provides a snapshot of how the education system is performing in the region and provides a basis that will help form a strategy to lift achievement.
The reaction from local principals speaks volumes.
The Ministry of Education could explain away its comments if the results were negative but let's not forget the latest report shows a positive lift in achievement in the Bay of Plenty.
The principals are - in effect - questioning data that suggests they are actually lifting achievement. The data collected for National Standards needs to be standardised or the system should be scrapped.
