Concern over a quarter of new primary teachers not passing NCEA Level 1 maths.

The Institute of Economic Research has analysed NCEA achievement of those starting between 2017 and 2022.

It found more than half didn't pass Level 1 science.

Deputy chief executive and principal economist, Sarah Hogan, says this confirms what other studies have claimed - that primary teachers are not equipped to teach maths.

"I guess what's new about here is that it's even worse for science."
