National has revealed it will overhaul what's taught in primary and intermediate school, to prepare students for high school.

The party is releasing its election-year education policy at 12pm.

It's promising to "rewrite the school curriculum" if it wins the election, with a focus on basic skills in reading, writing, maths and science.

Education Spokesperson Erica Stanford has revealed to Mike Hosking National will rewrite the Year 1 to 8 curriculum, rather than the high school curriculum.

She wants to make sure that kids who enter high school are at curriculum, so they can unlock all of the opportunities of high school.
