The primary teachers union says there are other matters which should come before improvements to the measuring of student performance

An Auditor-General report says there's a gap in the Ministry of Education's information on student performance before NCEA level.

It recommends better collection of progress reports on primary and intermediate students.

New Zealand Education Institute President Mark Potter largely agrees with the report.

But he says real student achievement won't be seen until problems with funding and support staff availability are addressed.
