What Activities Do You Need for the Common App? A Guide for International Students

TL;DR

• The Common App activities section has 10 slots. Quality of commitment matters far more than filling every slot.
• Admissions readers spend about 8 minutes on a full application. Your activity list needs to tell a coherent story at a glance.
• International school students often undercount what qualifies as an activity. Things you are doing right now probably belong on the list.

One of the most common questions students ask in Grade 11 is some version of "do I have enough activities?" It is usually the wrong question. The right question is whether the activities you have tell a story that a stranger could understand in under a minute.

The Common App gives you 10 activity slots. Each one gets a category tag, a position or role title (50 characters), a description of what you did and what it meant (150 characters), the number of hours per week, the number of weeks per year, and whether you plan to continue in college. That is it. No paragraphs. No room to explain context. Just compressed, precise language and a list of numbers.

Most students I have spoken to discover this format for the first time in September of Grade 12, then spend weeks trying to retrofit their high school experience into boxes that were not designed with them in mind. The students who do this well are almost always the ones who understood the format years earlier and made decisions with it in the back of their mind.

What Actually Counts as an Activity

This is where international school students consistently undercount themselves.

The Common App lists these as valid activity categories: arts, athletics, career, community service, family responsibilities, foreign language, journalism and publication, junior ROTC, research, religious activities, school spirit, science and math, social justice, student government and politics, technology, and other clubs and activities.

Family responsibilities is a real category. If you help manage a family business, care for a younger sibling, or contribute financially to your household, that belongs on your list. Admissions readers at selective US universities are trained to recognize and respect this.

Research is a real category. A personal project counts. You do not need a university lab affiliation or a published paper. A student who spent a summer independently studying the water quality of local rivers and producing a written analysis has research experience.

Other clubs and activities is a catch-all. If something you do regularly does not fit elsewhere, it fits here. A weekly chess group, a language learning commitment, a cooking channel, a self-directed coding project. If you invest real time in it, it counts.

The threshold question is simple. Does this require recurring commitment and produce something, whether a skill, an output, or a contribution to something beyond yourself? If yes, it belongs on the list.

What Admissions Readers Are Actually Looking For

The activities section is not a resume. It is evidence of who you are outside of class.

Admissions readers at selective universities are looking for two things. First, genuine commitment over time. Second, some coherence across the list — a sense that this is a real person with real interests, not a student who joined clubs strategically.

The well-rounded vs. spike debate has been going on for years. The short version is that most admitted students at highly selective schools are not well-rounded. They are distinctly good at something, with supporting interests that give texture to who they are. A student who is deeply committed to environmental journalism, runs a school podcast, and volunteers at a local conservation project has a coherent identity. A student who is in the environmental club, the debate team, the art club, the student council, and a community service organization has a list.

The spike does not need to be extreme. It just needs to be real. What do you actually care about? That is your anchor. Everything else can support it or contrast with it in interesting ways.

The 150-Character Problem

This is where most students lose points they do not realize they are losing.

150 characters is approximately one tweet. You cannot explain context. You cannot be modest. Every word has to do work.

A weak description looks like this: "Participated in school environmental club and helped organize events and raise awareness about climate issues."

A strong description looks like this: "Founded school's first sustainability committee. Led 3 student-run audits of campus waste. Reduced single-use plastic in cafeteria by 40%."

The difference is specificity and ownership. Numbers where you have them. Verbs that show agency. Results where they exist. The reader should finish your description knowing exactly what you did and what changed because of it.

For international school students, context sometimes needs to be embedded in the description itself. If you won a competition that a US admissions reader has never heard of, the description needs to communicate its significance without assuming they know what it is. "1st place, Qatar National Science Olympiad (top 3 of 200 applicants)" tells a reader everything they need without requiring them to Google it.

A Mistake Specific to International School Students

Many international schools run their own versions of activities that do not have direct equivalents in the US system. Model United Nations, Duke of Edinburgh, CAS hours under the IB Diploma, community service programs run by the school.

These are real activities and they belong on the list. The mistake is describing them in internal shorthand that a US admissions reader cannot decode.

"CAS supervisor approved 50 hours of creativity activity" tells a US reader almost nothing. "Led weekly ceramics workshop for 12 students as part of IB Diploma service requirement. Taught 3 foundational techniques over 8 months." tells them exactly what happened.

Translate everything. Never assume shared context.

How to Think About Your List Strategically

You do not need 10 activities. A list of 6 activities with real depth and strong descriptions is more compelling than 10 thin entries.

Rank your activities in order of meaning to you, not in order of what you think sounds impressive. The Common App asks you to list them in order of importance. Put what actually matters to you first. Admissions readers notice when the ordering feels calculated versus genuine.

Think about what your list says collectively. If you removed your name from it and handed it to a stranger, could they describe the kind of person who did these things? If the answer is no, the list needs either more depth in the existing activities or some consolidation around a clearer identity.

One pattern that works well for international school students specifically is anchoring around your local environment. Activities that engage with your city, your country, or your regional context can be genuinely distinctive. A student in Doha who researched the desalination infrastructure of the Gulf, or a student in Seoul who organized a cross-school debate on Korean education policy, has an activity that no American domestic student can replicate. That distinctiveness has value.

When to Start Building the List

Now. Whatever grade you are in.

The activities section is filled out in September of Grade 12, but it is built over four years. The students who write strong descriptions are the ones who took on real responsibility, produced something real, and stayed long enough to see it matter.

If you are in Grade 9 or 10, the most valuable thing you can do is find one or two things you genuinely care about and invest in them seriously. Do not rotate. Do not join things to fill a list. Ask what you would do even if no college was watching.

If you are in Grade 11, audit what you have. Which activities have depth and which are shallow? Where do you have leadership or ownership and where are you just a member? You still have time to take on more responsibility in existing commitments, which is more valuable than adding new ones.

If you are in Grade 12, work with what you have. The description quality and the framing matter enormously. A student who spent three years as a member of a debate team and can articulate exactly what they learned, how they grew, and what they contributed will present stronger than a student with a more impressive activity they describe vaguely.

How Ipsero Helps With This

One of the things Ipsero tracks is your activity list over time, not just at application season. You can log activities as they happen, note hours and responsibilities, and add journal entries about what something meant to you. When Grade 12 arrives and you sit down to write your 150-character descriptions, you are pulling from three years of notes rather than trying to reconstruct everything from memory.

Ipsero also maps your current activity profile against the profiles of admitted students at your target schools, so you can see early whether the story you are building is the kind of story those schools respond to.

If you are building your activity list and want a clearer picture of where you stand, Ipsero is worth looking at.

The activities section rewards students who started early, stayed consistent, and did things they actually cared about. That is not a formula. It is just what genuine investment looks like on paper.
