Nearly half of teachers tested on their understanding of national standards for student's writing got it wrong, casting doubt on schools' results.
A report for the Ministry of Education exposed a high error rate for teachers who were tested on their understanding of national standards, Radio New Zealand reports.
Of those teachers asked to judge examples of children's writing against the standards 49 percent got it wrong. In maths the error rate was 39 percent.
The ministry says error rates in final results will not be as high because these are based on a number of examples of each child's work.
However, the report calls into question the dependability of teachers' assessments.
The testing found that when teachers were wrong they tended to mark work better than it was.
The Green Party is now calling for the national standards website to be pulled down.
“The results are wrong and the site publishing them should immediately come down,” Green Party education spokesperson Catherine Delahunty says.
She says children are being written off as failures and schools are being judged on the data.
“It is common for information to be pulled from public websites when it has been proven to be wrong and that should happen here.”
Last week the Government published national standards data from nearly 2000 schools.
National standards are benchmarks in reading, writing and maths.
The results from the schools show how their students are performing against those benchmarks, and identify problems.
The standards were introduced last year.
