More research about The Middle School Plunge reveals:
"Our results cast serious doubt on the wisdom of the middle-school experiment that has become such a prominent feature of American education."
"entering a middle school causes a sharp drop in student achievement relative to the performance of those remaining in K–8 schools"
"After three years in a middle school, students who entered in 6th grade score 0.23 standard deviations in math and 0.14 standard deviations in reading worse than we would have expected had they attended a K–8 school."
We would be better off getting rid of middle schools and jr. highs. They are the worst time of a student's schooling.
