Common Core is one of the most aggressive attacks on individual personal choice and responsibility in recent history. If the monopoly holds it will essentially remove choice even from private and home school children. Anything which breaks the common core monopoly reinforcing personal choice for parents and children would be a positive move.
This is part of a monster bill for essentially non classroom expenditures on public education. Almost every sort of program is being subsidized. There is a provision that no more than 2% of the moneys can be used for administration, but then the programs themselves (which are hugely administrative) are defined as not administrative for the purposes of the legislation. This change in the bill would be one step to a more fiscally responsible state budget for education
In making the common core a district wide decision for the public schools, you have limited state and federal government control.
District control is far more local than state and federal control. It also allows for greater citizen involvement in decision making. Local or school by school control of such decisions would be even better but the government and the unions will resist it.
Common Core is designed as a monopolistic system. By coercing even private and home schools into the program is would seriously weaken free market solutions to our educational inadequacies
