The initiative gives state schools more control over finances and staff recruitment.
Mr Collier says 255 schools will be part of the independent schools program this year and so far the feedback from the schools involved has been very positive.
He says he expects that number to keep growing in the coming years.
"Most of the decision making at the local level in our schools is done at that level, not from head office," he said.
"So decisions with regard to staffing, with regard to resourcing, with regard to where decisions need to made for particular areas of need for a school are done at that level."
