Separate morning and afternoon schools could soon be trialled in NSW to reduce traffic peaks and address the enrolment boom, said State Education Minister Rob Stokes.

Mr Stokes said the design of the schooling system is in dire need of reform to cater to the new generation, with children beginning their education today set to end their working lives at the beginning of the 22nd century.

Similar to school systems that exist in countries such as France, the new proposal is a response to a report published by engineering firm Arup discussing school design.
