How will the new school funding system work?

It's been called a blunt instrument, discriminatory and hopelessly outdated, and now the end is in sight for the decile funding system for school. From next year, a new equity index will be introduced, funded by 75-million-dollars in the Budget. Schools will find out in September if they will be winners or losers when decile numbers are replaced. But the government has promised no schools will be worse off, at least for the first year.What will the changes mean for schools and students? And will it mean more children are enrolled at their local school? Kathryn discusses with Secondary Principals' Association President Vaughan Couillault; Te Pohue School principal Richard Gillespie and principal at Kaitaia Primary School, Brendan Morrissey.
