Schools' operations grants will rise 2%, but face a $70 million a year cut in their staffing in 2014 as a result of the Budget, delivered on Thursday.
The Government had earlier announced that changes to the staffing ratios used to allocate teachers to schools would save an average of $43 million a year over the next four years.
But the Budget shows the change will save nothing in the next financial year, $29 million in the 2013/14 financial year and more than $71 million in each of the following two years.
Most of the saving - about $65 million a year - will be in primary schools.
The Budget provides a 2% increase to school operations grants - worth about $20 million a year.
It also commits the first $33 million earned from state asset sales to upgrading school computer networks and a further $8 million in the next financial year to connecting schools to ultra-fast broadband.
As announced ahead of the Budget, spending on training for teachers and principals will rise by $59.8 million over the next four years.
The Budget shows overall spending on schools and early childhood education will rise by just over $300 million to $9.6 billion in the next financial year.
However, it shows that spending will decrease by nearly the same amount in the following year.
