Teachers in private schools aren't even required to be certified and many private schools don't worry about adhering to any type of national or state standards. what results are these teachers going by? 
Chugiak is a very good school district. If Alaska is pushed into a voucher program, how will districts like Chugiak respond to the flood of students from poorer, less successful districts? How will isolated, fly-in only communities benefit from a "choose your own school" system if there is only 1 school in their area? Will vouchers pay for plane tickets to fly these kids across the state to better schools?
