However, "The measure would apply only to El Paso County, where test-cheating and contract scandals have plagued the schools."
It's not hard to believe that school board members are corruptible, just like all government officials. But more paperwork won't solve the problem (though it will cost taxpayers a little more to administer). Corruption is guaranteed when some people have the power to hand out large amounts of other people's money.
And only in El Paso County? Like no other school boards have problems? Remember Mark Twain: "In the first place God made idiots. This was for practice. Then He made School Boards."
As long as government runs the schools, they will be ineffective, extremely expensive, and corrupt.
