The state’s entire education curriculum is to undergo its first overhaul in almost 30 years.

The review, spanning kindergarten to year 12, will attempt to declutter the current system, but Fairfax Media understands there will be a big focus on the primary years to give teachers more time to spend on literacy and numeracy.

NSW syllabuses for subjects such as maths, English and science are regularly updated, but the review will look mainly at so-called informal subjects that have been added ad-hoc over the years, such as driver safety and online security.

The review will consider updating classroom technology, put a sharper focus on Australian creativity and innovation, and clarify teaching of ‘‘general capabilities’’ – the learning skills emphasised in the recent Gonski report that students will need for a 21st century job market.
