New Zealand's educational ranking has fallen, according to the latest Organisation for Economic Cooperation and Development (OECD) report.
The Programme for International Student Assessment (PISA) report released overnight compares the performance of just over half a million 15-year-olds from 65 Organisation for Economic Co-operation and Development (OECD) countries.
It shows that while 15-year-olds who came through the New Zealand education system from 2001-2012 scored above the OECD average in maths, science, and reading, there had been big drops in New Zealand's ranking in all three subjects overall when compared to the last PISA report.
New Zealand's education ranking fell from seventh to 13th in reading, 13th to 23rd in maths, and from seventh to 18th in Science.
PISA found there has been a gradual slide occurring since the early 2000s.
