The Government's planning to use AI to grade almost all school assessments within three years

It's part of wider plans to scrap NCEA - replacing it with a system emphasising literacy and numeracy more.

President Chris Abercrombie says it's proved promising for simpler tests.

He says the NZQA's been impressed with it, checked by human markers.
