<p>If you take a look at the piece I linked to: </p>

<p>it discusses those studies in a great deal of depth. This would be a good starting point for anyone who really wants to understand the research. </p>
<p>The problem with the studies is they addressed only the question of whether the IQ benefit for Head Starters is maintained; not whether Head Starters have better school outcomes. IQ score is simply not the best measure of a program’s effectiveness.</p>
<p>And even then, the methodology was flawed. The studies omitted the special ed students (many of whom are in special ed because of their IQs). Since the non-Head Start population are more likely to be Special Ed, leaving them out skewed the results a lot, even on the narrow question of IQ. </p>
<p>Additionally, the studies treated all kids in the same grade as equals. Trouble is, the non-Head Starters tended to be older, since they’re more likely to be kept back a grade. So they’re really comparing children of different ages.</p>
<p>It’s pretty clear that Head Starters are less likely to be referred to Special Education, and that’s an advantage that benefits everyone in society (and persists well beyond fourth grade.)</p>

<p>Back to the original topic, the authors of the op-ed seem to be backpedalling a lot. They admit that they talked to very few Iraqis and that they had no way of independently verifying the claims made to them by Army officials. </p>

<p>At least one of them said that the security situation is better only by comparision to 2006, and that the political situation, which “trumps everything”, has not improved. He added that if the political situation continues to not improve, he would not be able to write such an optimistic piece in the future.</p>
