Yesterday, we looked at the first finding of Fordham's new groundbreaking study, Do High Flyers Maintain Their Altitude? Performance Trends of Top Students, which examines the achievement of individual high-performing students?or ?high flyers??over time. The report found that a majority of high flyers?nearly three in five?maintained their altitude across grades. The converse, of course, is that around 30 to 50 percent (depending on grade range and subject) of initial high achievers ?lost altitude? (earning them the designation of ?Descenders?). But the high-achieving pool did not shrink with the loss of the Descenders. On the contrary, it grew, thanks to an influx of students ascending into the high-achieving ranks (earning them the designation of ?Late Bloomers.?
These trends beg the question: For those students who ?lose altitude? over time, how far do they fall? And for those who climb into the top tier, how did they perform academically in earlier grades?
The answer: The majority of students who attained high-flyer status at one point in time did not stray far from it.
In other words, most of the students who entered or exited the 90th percentile did so from not far below it. As Figure 2 shows, in elementary/middle school math, the average student who fell below the 90th percentile by eighth grade only fell as far as the 77th percentile. And the average student...
