A good Common App activity description does three things in 150 characters: names what you did, gives it a scale with a number, and states a result. "Founded coding club; taught 60 students Python across 2 yrs; 4 members placed in state olympiad" does all three. "Member of coding club, participated in various coding activities and competitions" does none, and it is what most first drafts from Indian schools look like.
The section is small, ten slots of 150 characters, and it is read fast, well under a minute at most selective universities. That is exactly why the wording matters. There is no room for the reader to infer what you meant.
Why the activities section is harder than it looks
The Common App gives every activity four text fields and two numbers: a position or leadership description of 50 characters, an organisation name of 100 characters, a description of 150 characters, and the grade levels, hours per week and weeks per year. Ten activities, so 1,500 characters of description in total. That is fewer words than this article's first three paragraphs.
Most students treat the description as a place to say that they took part. Readers treat it as evidence, and evidence means specifics: how many, how long, what changed, who benefited. In five years of reviewing activity lists I have found that almost every list improves by a full tier when the descriptions are rewritten, before a single new activity is added. That is not because the reader is fooled by verbs. It is because the reader can finally see what was done.
The other structural issue is that the activities list is supposed to tell a cohesive story, which the Plinth Method frames as two pillars with most activities in their overlap. Descriptions written one at a time, each trying to sound impressive on its own, produce a list of ten unrelated claims. Descriptions written with the pillars in mind repeat the same nouns and the reader remembers them.
The fields and what each is for
| Field | Limit | What goes in it | What does not |
|---|---|---|---|
| Activity type | Drop-down | The closest category (Research, Academic, Community Service, Athletics, Work, Other) | Nothing; choose the one that matches the description |
| Position or leadership description | 50 characters | Your actual role, with a founder or captain title if true | "Member" when you can say something more specific |
| Organisation name | 100 characters | The club, company, lab or competition, with city if unclear | Your school's name if the school is already on the form |
| Description | 150 characters | Action, scale, result, in fragments | Adjectives, feelings, what you learned |
| Grade levels | Tick boxes | Every grade in which you did it | Grades where you were nominally enrolled but inactive |
| Hours and weeks | Numbers | Honest averages | Round numbers you cannot defend |
The 50-character position field is under-used. "Member" tells the reader nothing. "Founder and lead developer" tells them the whole structure of the activity before they read the description. If you had several roles, use the highest that was real, and put the progression in the description: "Joined Gr 9; captain Gr 11-12".
Verbs, metrics and the pattern that works
The pattern is action, scale, result. Each part is a fragment; semicolons separate them.
Action. Start with a verb that describes what you did, not what the activity was. Founded, built, taught, ran, raised, organised, coded, wrote, published, coached, negotiated, interviewed, tested, designed, recruited, trained. Avoid verbs that describe attendance: participated, attended, was part of, helped with, involved in. If you genuinely only attended, that is a signal to reconsider whether the activity belongs on the list at all.
Scale. A number that shows the size of the work. Students taught, money raised in rupees or dollars, users, downloads, participants, schools reached, hours coached, matches played, articles written, pages of code. If you have no number, ask why not. A number can almost always be counted after the fact, and if it cannot, the activity may not have produced anything.
Result. What changed because of the work. Placed, published, adopted by, still running, used by, won, selected for. This is the part most drafts leave out, and it is the part an admissions reader is looking for.
Two rules on numbers. Use numerals, not words, because "3" is one character and "three" is five. And give Indian rupee figures in the Indian format with a rough dollar conversion if there is room, or choose the one that reads faster: "₹1.2L raised" is clear to an Indian reader and confusing to an American one; "raised $1,400" is clear to both.
Before and after: six composite rewrites
These are composites drawn from many lists, not descriptions of any one student. Character counts are in brackets.
School club, no numbers
Before: "Member of the school's environmental club. Participated in various tree plantation drives and awareness campaigns within the school." (131)
After: "Led 3-school e-waste drive; 1.2 tonnes collected, ₹40,000 raised for 2 recycling units; team of 9; drive repeated by school in 2026" (133)
The second version is what the same student actually did once asked the right questions. Nothing was invented; the numbers were in a WhatsApp group.
Research, described vaguely
Before: "Conducted research on the effects of air pollution on health under the guidance of a mentor and wrote a research paper." (119)
After: "Independent study: PM2.5 vs school absenteeism, 4 Delhi schools, 18 months of data; regression in R; submitted to JEI, under review" (131)
Position field: "Lead author". Organisation: "Independent research, mentored by [university] PhD candidate". The journal name and the status ("under review", not "published") are honest and specific.
Sport, school-only
Before: "Played basketball for the school team for four years and was captain in Grade 11." (81)
After: "Captain Gr 11-12; state U-17 semi-finals 2025; started free Sat coaching for 25 kids at municipal court, 40 sessions and counting" (130)
Position: "Captain; volunteer coach". The third clause is the difference between a school activity and a pillar.
Entrepreneurship, oversold
Before: "Founded a startup that revolutionises the way students learn mathematics through an innovative AI-powered platform." (114)
After: "Built maths practice web app for CBSE Gr 8-10; 340 registered users, 61 weekly active; ₹18,000 revenue from 3 schools; Blue Ocean finalist" (137)
The rewritten version is smaller and stronger. The reader believes 340 users. Nobody believes "revolutionises".
Community service, the tutoring essay's cousin
Before: "Taught underprivileged children in my locality every weekend and helped them improve their English and confidence." (112)
After: "Taught English to 12 children of building staff, 2 hrs weekly for 2 yrs; 9 moved up a reading level on school assessment; recruited 3 peers" (137)
The reader is not judging the cause; they are judging whether it was sustained and whether it was measured.
Work, omitted entirely
Before: (not listed, because the student did not think a job counted)
After: "Weekend shifts at family stationery shop, Gr 10-12, 8 hrs/wk; ran inventory spreadsheet, cut stock-outs from weekly to monthly" (124)
Type: Work (paid). Work is one of the most under-reported activities from India, and one of the most respected by US readers, who see it rarely from international applicants.
Ordering the list
The reader anchors on the first two entries and skims from the fifth. Order by impact, which means, in sequence: the activity with the most verifiable external result, then the one with the longest commitment, then those that most clearly serve the pillars, then the rest. Do not order chronologically, do not put the school council first because it sounds official, and do not bury the job or the family responsibility at the bottom because it seems unglamorous. The how many activities piece covers ordering and the ten-slot question in more depth.
Cohesion is checked after ordering. Read the ten position fields in a column. If they read as two stories, a reader will remember them. If they read as ten, the list needs cutting, not more writing.
The honours section: five slots of 100 characters
Honours are recognition, not work. Each slot has a 100-character title, a level (school, state or regional, national, international) and the grade levels. The rule that prevents duplication is that the activity goes in the activities list and the award goes here.
Examples of the format:
- "Very High Commendation, John Locke Institute Global Essay Prize, Economics category" (international)
- "Gold Key, Scholastic Art and Writing Awards, Critical Essay" (national, since regionals feed a national round)
- "Paper accepted, Journal of Emerging Investigators, 'PM2.5 and absenteeism in Delhi schools'" (international)
- "Selected, Team India nominee, IRIS National Fair; top 20 of 1,100 projects" (national)
- "School topper, CBSE Grade 10, 97.4 percent; 1st of 240" (school)
Include the scale wherever the reader might not know it: "1 of 30 selected from 2,400 applicants" is stronger than the program's name alone. If you have more than five honours, choose by level and by relevance to the pillars, and fold the rest into the relevant activity descriptions. The competitions calendar marks which competitions are selective enough to lead the section.
What Indian students get wrong
School-only roles. Head boy, house captain, editor of the school magazine, president of the MUN society. These are fine activities, but a list of ten of them says that the student did what the school offered. Readers at selective US universities see thousands of such lists from India. One activity with a footprint outside the school gates, a competition, a project with outside users, a published piece, a job, changes how the whole list is read.
No numbers. Indian school culture rarely asks students to count anything they organised. The numbers usually exist: participants, money, sessions, weeks. Reconstruct them from messages, posters and photographs before writing. A list without a single numeral is a list of claims.
Adjectives instead of results. "Prestigious", "innovative", "impactful", "esteemed" cost characters and lower credibility. Cut every one and replace it with a noun or a number.
Certificates as activities. A two-day workshop, a MOOC with a certificate, a paid "internship" that produced no work. These belong nowhere on the list. The profile building service spends most of its diagnosis stage separating what was done from what was attended.
Hiding family responsibility. Caring for a grandparent, running a sibling's school pick-up, working in a family business. The Common App treats these as activities, and US readers value them. Indian students almost never list them.
Untranslated context. "Won inter-house elocution" means nothing to a reader in Massachusetts. "Won school-wide speech contest, 1st of 60 entrants" does.
What to do this month
Grade 12, before the early deadlines. Take the current list and rewrite every description to action, scale, result. Reconstruct numbers from records. Fill the 50-character position field with a real role. Reorder by impact. Then read the ten position fields in a column and ask whether they tell two stories. Do this in September so the list is fixed before the early-round deadlines on 1 November.
Grade 11. Start a running log now: one line per activity per month with the number that month produced. In August of Grade 12 the descriptions will write themselves from the log, and the numbers will be defensible. This is also the year to add the one activity with an external footprint, because in Grade 12 there is no time.
Grade 9 and 10. Do not worry about descriptions yet. Worry about doing things that will one day have numbers. The Grade 10 plan covers what those should be.
Where this advice stops
The 150-character standard is a Common App convention. UCAS has no activities list at all; super-curriculars are argued inside the three personal statement questions, in sentences, with reading attached. Singapore's NUS and NTU take an activity record that reads more like a CV, with less need for compression. Canada's UBC and Waterloo ask for short-answer profiles where the same numbers appear inside 100 to 250 word responses. And the Coalition application and university-specific portals such as the UC application have different limits: the UC allows 350 characters per activity, which changes the rhythm but not the rule. Action, scale, result works everywhere; only the character count changes.
