Parents, teachers and union officials have set off on a 45 mile walk to highlight cuts to school budgets.
The National Union of Teachers began the trek this morning with stops planned in Dronfield, Chesterfield and Clay Cross before making their way to Nottingham.
Simon Murch, joint divisional secretary of NUT Sheffield said: "The march aims to highlight the multiple crises facing our schools and the education system more widely with massive funding cuts, teacher recruitment, over-testing and a narrowing curriculum."
The union say Sheffield is set to lose out by £27m - enough to fund hundreds of teachers.
The Government has previously said the changes will mean fairer funding for schools.
