New Zealand educational achievement has dropped significantly in the core subjects of science, maths and reading, according to a OECD report.
Labour education spokesman Chris Hipkins revealed the details of the report - which is due for release this evening - in the House today.
It showed that New Zealand's ranking had fallen from 7th to 18th in science, 12th to 23rd in maths, and 7th to 13th in reading.
Education Minister Hekia Parata said she could not comment on the details of the report because it would not be released until 11pm.
Mr Hipkins said: "It's a wake-up call to the whole education system but also to the Government that their education approach isn't improving things and under National the decline of our education system is accelerating.
