Mercedes Schneider is one of the few people I know (outside of Congressional staff) who has read every word of the proposed legislation to reauthorize the Elementary and Secondary Education Act (now called No Child Left Behind).

In this post, she explains that both bills remove any penalties for parents who choose to opt out. It is up to the states to determine whether parents are allowed to opt out of testing, but there will be no federal penalties if they do.

In states that are either silent on the matter of opting out or that explicitly ban it, parents can still opt it. They are the parents, and they can decide what is in the best interest of their child.
