I don't mean to put you personally on the defensive by using the term "scapegoat". My apologies.
But, I used the phrase because I have personally heard the principal try to attribute the increased behavior problems at EMS to this population of students (which she said was only about 10 for 6th grade and that was described as an unusually large intake in any one year). When asked if the specific discipline issues being discussed were committed mostly or exclusively by these students, as she seemed to be suggesting, she backed down and acknowledged that the acts were really committed by a broader cross-section of students.
Our DC's experience has been that a broad range of students misbehave at EMS mostly because there is an absolute lack of real consequences for anyone -- ED students or otherwise.
