What Is Demonstrated Interest and Why Does It Matter?
Demonstrated interest refers to the signals you send to a college indicating you are genuinely interested in attending. According to NACAC’s State of College Admission report, schools that track demonstrated interest use it to predict yield: the percentage of admitted students who actually enroll. Schools with lower yield rates (like WashU, Tufts, and BC) are more likely to weigh demonstrated interest because admitting students who are likely to enroll protects against under-enrollment. Schools with high yield rates (Harvard, Princeton, MIT) do not need this signal because most admitted students enroll anyway.
Which Top Schools Consider Demonstrated Interest?
| School | Considers DI? | How to Show It |
|---|---|---|
| WashU | Yes (Important) | Visit, info sessions, ED, email engagement |
| Vanderbilt | Yes (Considered) | Visit, MOSAIC, ED, info sessions |
| Tufts | Yes (Important) | Visit, interviews, ED, email opens |
| Boston College | Yes (Considered) | Visit, info sessions, ED |
| CMU | Yes (Considered) | Visit, info sessions, ED |
| Emory | Yes (Considered) | Visit, interviews, ED |
| Tulane | Yes (Very Important) | Visit, ED, Tulane-specific app |
| NYU | Yes (Considered) | ED, campus events |

Which Top Schools Do NOT Consider Demonstrated Interest?
| School | Considers DI? | Why Not? |
|---|---|---|
| Harvard | No | High yield (~84%) |
| Princeton | No | High yield (~70%) |
| Yale | No | High yield (~72%) |
| Columbia | No | High yield |
| MIT | No | Mission-driven, no legacy preference |
| Caltech | No (officially) | Pure merit focus |
| Stanford | No | REA is the interest signal |
| UCLA | No | UC system, volume too large |

According to CDS Section C7, these schools explicitly mark demonstrated interest as “not considered” in their admissions criteria. This means campus visits, email opens, and info session attendance do not affect your admissions decision at these schools. However, visiting campus can still strengthen your essays by giving you specific details to reference. For how ED signals interest at schools that don’t track DI, see our ED vs RD guide.
Even when a school marks demonstrated interest as “not considered” in Section C7 of the Common Data Set, I do not think that means interest is irrelevant in every sense. In practice, colleges may define demonstrated interest differently. Some may not track formal signals such as email opens, campus visits, or webinar attendance, but they still want to see genuine engagement through the way a student approaches the application. That can come through in the specificity of a supplemental essay, the clarity of the student’s academic and extracurricular fit, or the overall thoughtfulness of the application.
For that reason, I always recommend that students take the time to engage with a school seriously, even when it officially says it does not consider demonstrated interest. Visiting campus, attending information sessions, speaking with current students, or simply spending time researching the school can help a student decide whether it is truly the right fit. Just as importantly, that deeper understanding often leads to stronger, more specific, and more convincing application materials.
How Do Schools Track Demonstrated Interest?
According to admissions professionals and NACAC, schools that track demonstrated interest use CRM platforms (like Slate, which is used by over 1,000 colleges) to log: campus visit attendance, info session RSVPs, email open rates and click-through rates, alumni interview participation, admissions event attendance, contact with regional admissions officers, and whether you applied ED or EA. Some schools assign a “demonstrated interest score” that is factored into the admissions decision alongside academics and extracurriculars. The most powerful signal is always the binding ED application, which guarantees enrollment if admitted.
Does Visiting Campus Actually Help Your Application?
At schools that track DI (WashU, Tufts, Tulane, BC, CMU, Vanderbilt): yes, meaningfully. A campus visit is logged in your admissions file and signals genuine interest. At schools that do not track DI (Ivies, MIT, Stanford): visiting does not directly help your admissions odds, but it can indirectly help by giving you specific material for your “Why Us?” essay. If you cannot visit in person, virtual info sessions and regional events count at schools that track DI. For building your overall profile, see our summer programs guide.
What Is the Most Powerful Form of Demonstrated Interest?
Applying Early Decision. According to CDS data across all schools that track DI, the binding ED application is the single strongest interest signal because it guarantees enrollment if admitted. At schools like WashU (61% of the class filled through ED), the ED application IS the demonstrated interest strategy. Other effective signals include: campus visits with registration, alumni interviews (where offered), and attending in-person info sessions. Email opens and website clicks are the weakest signals.

Common Mistakes with Demonstrated Interest
Three common mistakes: First, obsessing over demonstrated interest at schools that don’t track it. Visiting Harvard five times does not improve your odds. Second, neglecting demonstrated interest at schools that do track it. Not visiting WashU or Tufts when you live within driving distance sends a negative signal. Third, confusing quantity with quality: opening every marketing email is weak DI, while attending a campus visit and asking a thoughtful question to the regional admissions officer is strong DI.
Final Thoughts: Make Demonstrated Interest Part of Your Strategy
Demonstrated interest is a strategic tool, not a universal requirement. Know which schools on your list track it, and invest your time accordingly. At DI schools, visit campus, attend events, and apply ED. At non-DI schools, focus your energy on essays, academics, and extracurriculars instead.

No. According to Harvard’s CDS, demonstrated interest is “not considered” in admissions. This applies to all Ivies except possibly Columbia (which has varied its policy). Visiting Harvard does not affect your admissions decision, though it can strengthen your essays.
According to CDS data, Tulane rates DI as “very important.” WashU and Tufts rate it as “important.” BC, CMU, Vanderbilt, Emory, and NYU rate it as “considered.” These are the schools where campus visits, info sessions, and ED applications most meaningfully affect your odds.
Yes, by far. A binding ED application guarantees enrollment if admitted, which is the ultimate interest signal. At WashU (61% class filled through ED) and Vanderbilt (50%+), ED is not just DI, it is practically required for competitive odds.
Technically yes at schools that use Slate CRM to track email engagement. But it is the weakest form of DI. Campus visits, info sessions, and alumni interviews are far more impactful. Do not rely on email opens as your demonstrated interest strategy.
Only visit schools that track DI and that are realistic targets. Visiting Harvard (no DI tracking) has minimal admissions impact. Visiting WashU or Tufts (strong DI tracking) can meaningfully help. If you cannot visit, attend virtual info sessions and regional events at DI schools.
No. According to MIT’s CDS, demonstrated interest is “not considered.” MIT evaluates applications based on academics, extracurriculars, essays, and recommendations. Campus visits do not affect your admissions decision.
Not significantly. DI is a tiebreaker, not a substitute for academic credentials. A student with a 3.5 GPA who visited campus three times will not be admitted over a student with a 3.9 GPA who never visited. Think of DI as the final 5-10% of the decision, not the foundation.
Attend virtual info sessions and register with your real name and email. Attend regional admissions events in your area. Request and complete an alumni interview. Engage meaningfully with admissions officers at college fairs. Apply ED or EA. All of these are tracked by schools that consider DI.
