You wouldn’t say this if your child were rejected from every college. I know a few cases where that has happened. Safety schools realize they’re safety, and are likely to reject an applicant because they don’t want to negatively affect yield by admitting students who won’t matriculate. Unlike admit rates which serve a useful purpose, yield is primarily a marketing ploy. It hurts applicants severely by forcing them to apply to many more schools to avoid having nowhere to go in the fall.
