A secondary teachers' union is dubious AI could adequately grade almost all school assessments within three years.
The Government plans to replace NCEA with a system emphasising literacy and numeracy more.
The Education Minister is also now saying AI is already partly in use for marking - and NZQA is confident it could do almost all assessments by 2028.
PPTA President, Chris Abercrombie, says he isn't convinced.
"Seeing how the students write, understanding, reading between the lines - sometimes you have to figure out what the students are trying to say and I just don't know if AI is quite there yet to be able to do those kinds of things."
