ELI5: No Child Left Behind and its lack of success.

I have heard how "No Child Left Behind" has been a failure multiple times from both political ends.  What is the policy exactly, and why does it not seem to pull through with its objective.

No Child Left Behind basically says that schools where kids don't do well on standardised tests will be punished with less funding. 

Many people don't like standardised tests, but more importantly, taking money from schools where kids are failing is like telling a sports team you won't feed them until they play better. 

Students who are failing need *more* funding at their school to help them do better, not less. It's a complicated issue though, because you can't give more money to schools where kids are failing, because then there's no incentive to improve. 

I don't think anyone thinks it's an easy problem to solve, but taking money from the worst schools is the worst possible solution.
