I think you are misunderstand what the originally cited article meant by high stakes. I recommend reading the article itself rather than my brief excerpts from it, but here's another key paragraph from it.
The tests were not being used as a graduation requirement, but the high stakes schools faced for poor performance inevitably affected the way the principals and teachers did their jobs. There was a benefit to getting rid of poor performers, which means there was (probably not consciously or deliberately) little effort to encourage potential dropouts to stay.
The book I reviewed showed how high-stakes testing affected a middle school. I'm sure the designers of NCLB explicitly warned against teaching to the test, but in practice, that has been the near universal response of educators whose jobs or raises have depended on measured performance on it. In the excerpt of my review that I quoted in the original posting, I state, "This behind-the-scenes view of a real school at work reveals that Tyler Heights would be a success story whether its students are tested or not."
The school is considered a poster child for NCLB, but the truth is more complex--or perhaps it is simpler. This school was led by Tina McKnight, a gifted principal who knew that her job was to facilitate learning, no matter the external requirements imposed by the board of education. She had to use a curriculum that directly addressed how to perform better on the NCLB tests, but as I note later in the review:
NCLB is a great example of what engineers like to call "the Law of Unintended Consequences." The data show an increase in high school dropouts, and it is not unreasonable, given further research, to recognize that the increase is an unintended consequence of this particular approach to making educators more accountable for the results of their work.
