Start by eliminating public schools and replacing that system with a 100% voucher system designed to finance no-frills serious academic education only. Plenty of schools will pop up which keep their costs at or below the voucher level. If people want their children to go to schools with big sports facilities and other extras, let them pay for it themselves.
Vouchers are a fix for the current system. With a national system we loose a lot of special interest groups. We get standard testing controlled at the higher national level. I see the cabinet of Education position becoming what it is meant to be.
this is a start. Make sure HISTORY course is included.
