Valid yield figures will not exist until after the semester starts and they count all who actually showed up. However, unless Stanford is lying publicly, its expected yield for this year is about 80% and maybe little higher. Last year yield was also 80%, which is determinable from its common data set so this year should be comparable. I have not heard about Stanford now refusing to provide information called for in the common data set. I do not see the world changing if a college with a known very high yield now declares it won’t tell anybody what it is anymore. Moreover, I do not believe any public service is done when any college decides to conceal information from the public. If Stanford is going to be hiding figures, I hope it is not because it wants to keep things secret so it can avoid in the future class action lawsuits like one that has been filed against Harvard accusing it of reverse discrimination based on its publicly available admission and yield figures.
