The kind of hook you are talking about for schools like Yale is being nationally or internationally known for something. Famous actors, top athletes in sports that aren’t college team sports, top competition winners in sciences, national champs in academic competitions, etc. It is not impossible, but very, very difficult to break through and differentiate yourself for the very top schools if you don’t have one of the more traditional hooks.
So… do yourself & your kid a favor. Focus more on match and safety schools starting fall of junior year. For every top school she visits, go see 3 others that are matches or safeties. For some students it is harder to find some they really like, so it takes more elbow grease.
As a parent, don’t talk about “Ivy material” (how is that going to make her feel if she doesn’t get into one?). Your job is to set the tone for her search. Focus on finding a list of safety, match, and reach schools, any of which she would be pleased to attend. Keep the focus on the list, not on one favorite school or just the reach schools. Look at academics, ECs, vibe/environment, affordability (if you need to). On visits, dig in past the tour, which is a marketing tool. See if she can sit in on a class, and eat in the cafeteria. Eavesdropping and people watching there can be quite revealing. Encourage her to read the student paper to see what students are talking about.
Neither of my kids went to the top ranked school they got into. One turned down a top 3 university for fit reasons, and several years later is very glad she did.
