New research suggests children would benefit from starting preschool at the age of three.

The Mitchell Institute has recommended putting children in school earlier, in a bid to give students a ‘more equal footing’.

Researcher Stacey Fox says there are advantages of starting early.

‘We really have an opportunity to boost the lifetime outcomes of all children, and to make a real substantial contribution to Australia’s social and economic prosperity into the future.’ She told 3AW News.
