One Significant Difficulty with the Initial No Child Left Behind

One significant difficulty with the initial No Child Left Behind law was that

A) the initial grants offered to states were too low to motivate compliance.
B) the federal government lacked bureaucratic manpower to analyze the data it demanded the states collect for it.
C) the questionable constitutionality of the act slowed state agencies' desire to follow it.
D) states were allowed to set their own standards for what constituted acceptable student performance.
E) too many tasks necessary for implementing the law were outsourced to private for-profit education companies.
