What is minimal 1%,  2%, 5%, 10%?  I believe Calgary has the largest public system in Canada (anyway that is what the superintendent tells us).  I believe the superintendent's staff admin, office rent etc is between 3-4% of the budget.  And so eliminating one of them would be a cost savings.  As well the busing costs moving kids from a neighborhood with a catholic school to one with a public school ( & vice versa) is an unnecessary cost.  Finally, I suspect there could easily be a 5% savings which is not minimal.
