After more than 20 years as New Zealand's official secondary-school qualification, the government has pulled the pin on the NCEA. By 2030, the National Certificate of Educational Achievement will be gone. It will be replaced by a basic literacy and numeracy award at Year 11, and the Certificate of Education and Advanced Certificate of Education at Years 11 and 12. No more achieved, not achieved, merit and excellence - instead there will be marks out of 100 and letter grades like A B and C. Education correspondent John Gerritsen reports.
