An Introduction to College Application Jargons

Published Mar 25, 2026 Updated May 27, 2026

Decode the jargons of college applications to understand the roles, systems, and processes behind it.

I want to start here by laying out a few terms and using them to introduce some of the key parts of the college application process. A lot of these words sound like pure jargon the first time you hear them, but once you put them back into the actual application process and understand them in context, you realize that each one maps onto a different person, system, or evaluation mechanism. If you get these basic concepts straight first, then later, when you move on to more concrete topics like building a college list, essays, and recommendation letters, everything becomes much easier.


Admission Officer

Abbreviation: AO

An admissions officer is the person at a university who is responsible for admissions. They read your application materials, evaluate your academic ability, personal experiences, and potential, and ultimately decide whether to admit you.

Beyond that, an AO’s responsibilities usually also include:

The work of an admissions officer sounds very formal and professional, but as applicants, the most direct experience we usually have is through our actual interactions with them, and through how they end up interpreting your application materials. What follows is more my own observations and thoughts about admissions officers’ work style and depth of expertise.

I’ve always felt that the role admissions officers play in a university is pretty similar to the role HR plays in a company — both are just workers sifting through stacks of material doing screening. That said, when it comes to professional judgment, AOs and HR are actually a bit different. A lot of company HR or recruiters may in fact be more familiar with a relatively specialized field, because they look at resumes in that area every day and deal constantly with hiring managers in that area. Over time, they at least develop an experience-based sense of the common backgrounds, common projects, and rough level within that field. By contrast, AOs have to deal with applicants from every discipline and every type, from humanities to STEM to the arts, so it’s hard for them to have especially deep expertise in any one specific area. Precisely because of that, unless you have one of those top-tier awards that even an outsider can recognize at a glance, what gets you admitted often isn’t just technical depth. It’s whether you can communicate your story, motivation, and potential in a way that’s compelling enough (and of course the story needs to be backed by real, relevant experiences, not built on thin air). I’ve heard that quite a few schools ask professors to help review applications, but logically speaking, many professors are already overwhelmed with their own work, so they may not have that much energy to invest in this kind of thing over the long term. Still, I don’t know that side particularly well, so readers who do are very welcome to correct me. Looking ahead, as AI-assisted tools gradually enter the admissions process, this may slowly change as well.

One more thing worth knowing: most AOs don’t get applications assigned to them at random; they’re divided up by geographic region. A university will often have someone specifically responsible for applications from China, and many universities even have an AO dedicated to UWC students. That means while they may not be able to make deep judgments on specific subjects like CS, physics, or economics, they tend to be very familiar with the UWC curriculum (IB), its grading standards, and the weight of different activities. This also helps explain why we as UWC students enjoy a kind of insider advantage when applying. This is because this environment is already recognized, understood, and to a large extent trusted by AOs. So for applicants, you don’t need to keep explaining in your essays what IB is, what the EE is, or what CAS means, which means you can save that limited space for content that better reflects who you are as a person.


College Counselor

Abbreviation: counselor

If AOs are the HR of a company, then counselors are more like your agent, the ones who “sell” you to universities. At a school like UWC, the counselor’s role is crucial, because they are the first bridge through which universities get to know you.

Their core responsibilities mainly include:

How to Work with Your Counselor

I’ve noticed that people tend to swing to one of two extremes when dealing with counselors: either they over-ingratiate themselves, thinking that winning over the counselor is the key to everything; or they stay completely transparent and only show up at the last minute to get forms filled out. A few things worth keeping in mind:

An Important Nuance About Recommendation Letters

Among the three required recommendations, the counselor’s letter is the single most important one, bar none. (I’ll go into detail about which three letters those are in the Letters of Recommendation section below.) The reason is that counselors tend to have much more philosophical conversations with you than your subject teachers do. Compared with the other two teacher recommendations, the counselor understands best who you are as a person, how you think about high-level questions, and where you are in terms of maturity — which happen to be exactly the things U.S. universities care about the most.


Common Application

Abbreviation: CA

Common App is the most widely used online application system for undergraduate admissions in the United States. Through Common App, students can fill in their basic information and core essay once, then send those materials to multiple partner schools, which greatly simplifies the application process.

Still, Common App is more like a unified entry point than something that turns every school into the same exact task. Many schools add their own supplemental essays, supplemental questions, or extra material requirements on top of Common App. So the best way to understand CA is not to treat it as “fill out one form and you’re done,” but to see it as the most basic and most commonly used underlying platform in the application process.


Essays

Essays are the part of the application that best captures the human side of you. Unlike grades and standardized tests, they aren’t a hard metric; and unlike recommendation letters, they aren’t written by someone else.

In terms of composition, essays fall into two main categories:

Essays deserve an entire guide of their own. Here I just want to flag a few of the most common pitfalls:


Letters of Recommendation

Abbreviation: rec letter or LoR

Common App requires three recommendations total: one from your counselor and two from subject teachers (usually two of your DP1 or DP2 teachers). On top of that, many schools allow — and sometimes encourage — an optional additional letter (for example, from your EE supervisor, a CAS mentor, or a research mentor).

Of the three, the counselor’s letter is the most distinctive one, and I’ve already gone into it above. The two teacher recommendations are more about endorsing you academically: what you’re like in class, how you think through problems, and whether you have curiosity that goes beyond the textbook in your subject.

A few pieces of advice about choosing which teachers to ask:


Early Decision / Early Action / Regular Decision

Abbreviation: ED / EA / RD

These three are the three application timelines in U.S. college admissions:

ED admit rates are usually noticeably higher than RD, but there are a lot of confounding factors: the ED pool often includes recruited athletes, legacy applicants, and some very strong students who’ve long since made up their minds about where they want to go, so the surface-level number doesn’t mean ED is that much “safer.” I think the question actually worth asking is: is there a school you’d 100% want to attend if admitted, one that’s truly a good fit for you? And on how to pick a school that’s a good fit, you’re welcome to read On Choosing Colleges.

One more UWC-internal rule worth mentioning here: UWC Changshu China caps the number of college applications each student can submit at 10. The official policy explains that applying itself is very time-consuming and that submitting too many drags down both your academics and the quality of each application — so the school wants you to focus on choices that actually fit you. The UK’s UCAS system, the U.S.’s University of California system, and Canada’s Ontario Universities system each count as 1 application rather than having each school within the system count separately, so if you’re applying to these systems your actual reach is a bit broader than the number 10 would suggest. It’s worth factoring this cap into how you plan out your ED, EA, and RD slots early on.


Liberal Arts Colleges / Research Universities

Abbreviation: LAC

In U.S. undergraduate admissions, the single biggest structural divide is between Liberal Arts Colleges (LACs) and Research Universities. Both types of schools grant a Bachelor’s Degree, but their underlying philosophy and campus experience are very different.

For UWC students, there are a few things about these two categories worth noting in particular:

Which side you pick ultimately comes down to what you want: if you want deep faculty-student interaction, a tight-knit community, and undergrad-centric resources, a LAC will suit you better; if you want richer research opportunities, a wider range of courses, and a more diverse campus environment, a research university has the advantage. There’s no better or worse — just whether it fits.


IB Grade

Related term: Predicted Grade (PG)

As a UWC student, your IB grade is the single most important academic metric in your college applications. Here’s a quick explanation of how it’s calculated and how it’s used in applications.

Grade structure: the IB Diploma is out of 45 points total, made up of two parts:

The threshold for earning the IB Diploma is a total of at least 24 points, plus passing all core components.

Predicted Grade (PG): what U.S. universities see when reviewing your application isn’t your final IB grade (at the time of application, you’re still in DP2, and the actual exams don’t happen until May). What they see is UWC’s predicted grade. Your PG is set by your subject teachers based on your DP1 results and your performance in the first month of DP2, and it gets submitted together with the rest of your application through Common App. For UWC students, the PG is the single most important academic metric in your application season.


Standardized Tests

For international students, the common standardized tests fall into two categories:

One big change in the last few years has been the Test-Optional policy. During the pandemic, nearly every U.S. university went Test-Optional, letting you choose not to submit SAT/ACT scores. But over the most recent application cycles, a number of schools have started reinstating their testing requirements. This policy shifts every year, so always check the latest information on the school’s website for the specific year you’re applying.

Concrete advice for UWC students:


Financial Aid

U.S. financial aid mainly falls into two categories:

For international students, the most important distinction is between Need-blind and Need-aware:

Applying for financial aid requires submitting additional forms like the CSS Profile (required by most private universities) or ISFAA. These forms ask you to disclose family income, assets, property, and so on in detail — it’s a nontrivial amount of work, so it pays to start on them early.


UWC Davis Scholars Program

This is a program exclusively for UWC students, founded by American philanthropist Shelby M.C. Davis. The Davis Foundation provides funding to many U.S. partner schools specifically to support UWC students who are admitted. For us, that means:


Holistic Review

Holistic review is a phrase top U.S. universities have on the tip of their tongues. Put simply, AOs don’t just look at your scores — they evaluate you as a whole person. That means your academic grades, extracurricular activities, personal qualities, essays, recommendation letters, and background all get considered together.

This kind of review uses a completely different logic from East Asia’s gaokao-style “one test decides everything.” Under a holistic framework:

Holistic review tends to work in UWC students’ favor. The way UWC develops students is inherently whole-person — IB, CAS, all kinds of committees, community work — which lines up naturally with what holistic review is looking for. Which also means the reverse is true: if you spent your two years at UWC only grinding for scores, without building out the story of a whole person, you’re actually competing hardest on the track that suits you least.


Activity List / Honors

Common App has two related sections:

These two sections are where the AO reads, in a very short window, who you are. Because the character limits are so tight, every word has to earn its place. A few common practices:


Interview

U.S. college application interviews are overwhelmingly conducted by alumni, not by AOs. They usually happen after you submit your application but before decisions come out, in the form of a Zoom call or a local coffee meeting, and typically last 30–60 minutes.

A few things that might not match what you’d expect:


Waitlist / Deferral

In addition to Admit and Reject/Deny, there are two intermediate outcomes you might receive:

Both outcomes can easily drag you into long-term mental anguish. A healthier mindset is that once you’ve submitted your LOCI or update, turn your attention back to the other schools still pending, or to doing DP2 well — not to refreshing your inbox every day.

Closely tied to the waitlist is a less-talked-about phenomenon called Yield Protection (sometimes half-jokingly referred to as Tufts Syndrome): some schools will waitlist — or even outright reject — applicants they judge to be too strong to actually enroll there, in order to protect their yield rate. This helps explain the occasionally counterintuitive pattern where a student gets waitlisted by a supposed match / safety school while being admitted to a more reach-y one.


A Closing Note: Demystifying the Mindset

Having walked through all of these terms, the one thing I most want to flag is: don’t mythologize AOs, and don’t mythologize the application system. At the end of the day, even the most complex systems are made up of people, and admissions officers are, at their core, just ordinary workers standing at a particular post. Like HR at a big company, they’re filters running themselves ragged through an enormous amount of information — which means they have their own aesthetic fatigue, their own cognitive limits, and, yes, their own mood swings too.

The same logic applies elsewhere in the process: Common App isn’t some kind of tribunal — it’s just an underlying platform for self-modeling, testing how well you can compress information within a limited character count. And your counselor is the agent standing next to you — they need to see the real, vivid, even occasionally clumsy version of you in order to write a recommendation with any soul to it.

The reason I want to break down this jargon so plainly is that this demystified perspective is exactly the kind of mental preparation every applicant needs most.

Once you stop blindly worshipping these roles and systems, you’ll realize that the core contest of application season isn’t about how perfectly you perform, but about whether you have the courage to face what’s actually true about yourself. An acceptance doesn’t mean you’re a genius, and a rejection doesn’t mean you’re mediocre. Once you bring these people back down to the level of professionals who need to be convinced, you’ll find that communicating from a place of equality and honesty is usually far more effective than scheming to engineer a perfect persona. After all, amid the noise of engineered personas, an un-alienated authenticity is the rarest signal of all. (Recommended reading: Victims of the System.)
