This article doesn't make a lot of sense. The author has discovered that there are multiple ways of meeting a minimum standard. She then observes that one way is to exactly meet the standard, and another way is to drastically exceed it. Somehow this means they are flawed and can't work. Are math standards also fundamentally flawed because while the standard may specify only multiplication of 4 digit numbers, some students can also do calculus?
