"Show demonstrated interest" is advice that gets repeated to every applicant, regardless of where they're applying -- which is exactly the problem. It only matters at some schools, it's tracked more literally than most students realize, and the schools you'd assume care most about it (the Ivies, MIT, Stanford) are often the ones that explicitly don't.

What demonstrated interest actually is

Demonstrated interest is the evidence a college collects that you genuinely want to attend, separate from your grades, scores, or essays. It's not one gesture -- it's a pattern of tracked engagement that admissions offices increasingly log through the same kind of CRM software (commonly a platform called Slate) that sales teams use to track customers.

What actually gets logged, per how these systems work: whether you open and click links in emails from the admissions office, how much time you spend in the applicant portal and which pages you visit, whether you register for and attend virtual or in-person events, whether you submit an inquiry form, and any direct contact with a regional admissions representative that gets entered into the system.

What generally does not count, even though students assume it does: following the school on social media, watching an unofficial campus tour video on YouTube, or talking to a rep at a college fair where nobody scanned your information card. If it isn't logged in the school's own system, it isn't demonstrated interest as far as admissions is concerned.

Who actually tracks it -- and who explicitly doesn't

All eight Ivy League schools, plus MIT, Stanford, and Caltech, explicitly do not consider demonstrated interest. These schools receive far more applications than they could ever admit and have consistently high yield rates regardless of who shows interest beforehand, so there's little practical reason for them to weigh it.

Roughly 40-45% of colleges do consider it, concentrated heavily among small and mid-sized private schools -- Tufts, Tulane, Boston College, Carnegie Mellon, and Vanderbilt are commonly cited examples. These schools tend to have lower yield rates and a real, practical interest in admitting students who are likely to actually enroll.

The most reliable way to check any specific school: every accredited college publishes a Common Data Set each year, and Section C7 ("Level of applicant's interest") tells you directly whether a school marks it Very Important, Important, Considered, or Not Considered -- more reliable than any blog's guess, including this one, since it comes straight from the school.

A current example of why this is shifting: WashU, 2026

In April 2026, Washington University in St. Louis announced it would begin tracking demonstrated interest for the first time ever, starting with the cycle for the Class of 2031 -- alongside adding an Early Action round for the first time and a new scholarship priority deadline. WashU's own admissions site lists campus visits at the top of what counts, alongside attending virtual info sessions ("Bear Chats") and signing up for its mailing list. Admissions observers read the combination -- a new EA round plus new interest-tracking, arriving together -- as a direct response to years of rising application volume: more applications per student nationally makes it harder for any individual school to tell who's actually likely to enroll if admitted, and demonstrated interest is one of the more direct signals available for sorting that out.

The "yield protection" theory -- real, but less proven than it sounds

You'll often hear demonstrated interest connected to "yield protection" or "Tufts syndrome" -- the idea that a school will reject or waitlist a clearly overqualified applicant specifically because it assumes that student will get into a more prestigious school and go there instead, hurting the rejecting school's yield rate (and therefore its rankings). It's worth being honest about this one: while yield rate is a real metric schools care about, and demonstrated interest is a real, documented factor at many schools, there's no official confirmation from any specific college that it rejects strong applicants purely to protect yield -- it's a theory that fits some observed outcomes, not a practice any school has confirmed. Treat "yield protection" as a plausible explanation for a pattern, not an established fact the way demonstrated interest tracking itself is. This is exactly why a "safety" school isn't actually guaranteed, even when your numbers clear the 75th percentile.

What this means for you

  • Don't spend energy demonstrating interest to schools that don't track it. If you're applying to an Ivy, MIT, Stanford, or Caltech, that time is better spent on your essays and the rest of your application -- interest tracking isn't part of how those schools decide.
  • For schools that do track it, the highest-value actions are usually the most obvious ones: visit campus if you can, open and engage with admissions emails, attend a virtual info session, and write a genuinely specific "why us" supplemental essay rather than a generic one that could apply to any school.
  • Check Section C7 of each school's Common Data Set before assuming anything -- guessing based on a school's reputation or selectivity isn't reliable, and policies change (as WashU just showed).
  • If a school on your list tracks demonstrated interest and it's genuinely not your top choice, still engage with it a little -- even a modest, honest level of interaction is usually enough to avoid looking like you have zero intention of attending, without requiring you to fake enthusiasm you don't have.
