There has been some controversy in Stoughton, MA where a teacher rescinded a letter of reference after learning that the student had made a swastika at school. (That teacher was then suspended for 20 days without pay over the incident.)
Please let this serve as a reminder that your character counts and your actions after you submit your applications can still impact your admissions chances. The usual culprit for a rescinded offer is plummeting spring semester senior year grades, but detrimental conduct can accomplish the same task as it did with this student.
We don’t want to opine on the teacher’s punishment as we’re probably not aware of all sides of this story but we know the colleges appreciate recommender integrity. We don’t believe they will punish this school system’s students for the actions of this one student, but they will be a bit more wary of trusting letters of reference when they know the teachers can be punished for speaking out on egregious actions that may occur after the applications are submitted.
