In recent years, the number of kids scoring 700 or higher on SAT tests has been increasing. For example, the number of students with 700-800 scores on Math has gone up from 75,000 in 2001 to 112,000 in 2011. There are no doubt a lot of reasons for this, such as ambitious students who would have only taken the ACT in the past because it's the default in their region now taking both the ACT and the SAT, and more foreign elite students taking a shot at the SAT.
TO date, no study has found any long-term benefit of attention-deficit medication on academic performance, peer relationships or behavior problems, the very things we would most want to improve. Until recently, most studies of these drugs had not been properly randomized, and some of them had other methodological flaws.
But in 2009, findings were published from a well-controlled study that had been going on for more than a decade, and the results were very clear. The study randomly assigned almost 600 children with attention problems to four treatment conditions. Some received medication alone, some cognitive-behavior therapy alone, some medication plus therapy, and some were in a community-care control group that received no systematic treatment. At first this study suggested that medication, or medication plus therapy, produced the best results. However, after three years, these effects had faded, and by eight years there was no evidence that medication produced any academic or behavioral benefits.
