Do you know what improves performance on tests, particularly those that do not require much in the way original thought?

If you are thinking cramming data you might be right, but this is not how Michelle Rhee is using her jihad against to hurt our children.

Have you ever had a strong cup of coffee to get on the bubble for a test? How about amphetamines? The military has used them for years to maintain focus for fatigued soldiers

How about Ritalin?

Ritalin, like other stimulants will improve performance in the short term, so it is no surprise that aggressive testing incentivizes schools to put children on stimulants:

There has been a lot of public agonizing lately about the steep rise in diagnoses of ADHD over the last two decades. There is growing, and justifiable, worry that a lot of kids are being put on stimulant medications who don’t need them.

What there hasn’t been is a plausible theory about what’s driving this explosion of diagnoses — 40 percent over the last decade and more than 50 percent over 25 years. The CDC now estimates that 12 percent of school age kids, and as many as 20 percent of teenage boys have been diagnosed with ADHD.

………

Now comes a book that, finally, offers a data-based analysis that could begin to account for an increase on this scale. “The ADHD Explosion,“ by Stephen Hinshaw and Richard Scheffler, considers all kinds of factors that may contribute to the surge, from diagnosis by undertrained and harried pediatricians to pharmaceutical advertising. But the eye-opening insight from Hinshaw, a clinical psychologist, and Schleffler, a health economist, who are colleagues at University of California, Berkeley, is the correlation between educational policies and the prevalence of ADHD diagnoses.

Using Centers for Disease Control surveys, Hinshaw and Sheffler found that when rates of ADHD diagnoses are broken down by state, it turns out that there are dramatic discrepancies. Based on the most recent survey, from 2011, a child in Kentucky is three times as likely to be diagnosed with ADHD as a child in Nevada. And a child in Louisiana is five times as likely to take medication for ADHD as a child in Nevada.

And these states aren’t just outliers. The five states that have the highest rate of diagnoses — Kentucky, Arkansas, Louisiana, Indiana and North Carolina — are all over 10 percent of school age children. The five states with the lowest percent diagnosed — Nevada, New Jersey, Colorado, Utah and California — are all under 5 percent. The disparity is even greater for kids prescribed ADHD medication. The same five states are at the top of the list, all of them with over 8 percent of kids getting medication. The states at the bottom of the list for medication — Nevada, Hawaii, California, Alaska and New Jersey — are all under 3.1 percent.

………

What the team found was that high rates of ADHD diagnoses correlated closely with state laws that penalize schools when students fail. Nationally, this approach to education was enacted into law in 2001 with No Child Left Behind, which makes funding contingent on the number of students who pass standardized tests. In more recent years, similar testing-based strategies have been championed by education reformers such as Michelle Rhee. But many states passed these accountability laws as early as the 1980s, and within a few years of passage, ADHD diagnoses started going up in those states, the authors found, especially for kids near the poverty line.

ADHD diagnoses of public school students within 200 percent of the federal poverty level jumped 59 percent after accountability legislation passed, Hinshaw reports, compared with less than 10 percent for middle- and high-income children. They saw no comparable trend in private schools, which are not subject to legislation like this.

How do ADHD diagnoses help schools at risk of losing their funding? First, Hinshaw notes, for kids who do have ADHD, it should improve their performance in school, including their test scores. Second, it may help kids who are disruptive in class settle down, which could improve scores for the whole class. Finally, in many areas, the test scores of student with ADHD diagnoses aren’t counted. So even it if it doesn’t help the child, it might help the school.

The researchers missed the point that I made, that giving your kids uppers will help with their tests, even if they suffer from strokes or sudden heart failure at age 14, it’s no skin off of the nose of Michelle Rhee and her ilk, if they hit their numbers, they win, and if they don’t they convert the “failing” to hedge fund backed charter schools, and they still win because they have a future career as a well remunerated executive at an “educational foundation”.
