Losing kids in the transition to middle school

EdWeek has a report on a new study on the transition to middle school being the particularly tough one:

For the Florida study, Mr. West and Guido Schwerdt, a researcher with the Ifo Institute for Economic Research at the University of Munich in Germany, used the state’s longitudinal database to track more than 450,000 students in the state’s public schools who proceeded from grades 3 to 10 between 2000-01 and 2008-09.
They found students who attended elementary schools ending at grade 5 had an early edge over those attending K-8 schools in mathematics and language arts, but their performance in both subjects dropped dramatically when they switched to middle school in 6th grade. After the 6th grade transition, middle school students fell by .12 standard deviations in math and .09 standard deviations in reading compared with students at K-8 schools, and then that gap continued to widen throughout middle school and into high school.
Moreover, students who had attended a middle school were 18 percent more likely than students who attended a K-8 school before high school to not enroll in grade 10 after attending grade 9—an indicator that they may have dropped out.
