The Common App Activities List has 10 slots. Each slot has a 50-character title field, a 150-character description, and a 'position/leadership' field. That's it. Nine hundred and fifty characters total per activity, with the 150-character description doing 95% of the work. Most students waste those characters on nouns and adjectives. The strongest applicants use them on verbs, scope, and outcomes.
What admissions reads in 5 seconds
An admissions officer reads 30+ files a day during peak season. They get about 5 seconds per activity entry on first pass. In those 5 seconds they want to know: what did you do, how big was it, and what changed because of you.
Here's the same activity written two ways:
Weak (108 characters used out of 150)
Strong (149 characters used)
Both describe the same activity. The first one tells you nothing — every robotics-club president 'led meetings.' The second one tells you scope (22 members, $4,200, 6 sponsors, 14 mentees), action (built, raised, led), and outcome (state semifinals).
The formula
Each description should answer three questions in this order:
- Action verb + scope. Not 'helped with' but 'led 22-member' or 'designed 7-week curriculum for' or 'recruited 41 volunteers across' — concrete, specific, scoped.
- Concrete deliverable. Not 'organized events' but 'launched annual hackathon now in 4th year' or 'wrote 9 articles published in the school paper.'
- Measurable outcome. Not 'helped people' but '$4,200 raised' or '14 middle-school mentees retained year-over-year' or 'top 5% nationally.'
Verbs that move the needle
Strong action verbs (use these): Founded, Built, Designed, Led, Recruited, Raised, Coordinated, Coached, Mentored, Organized, Wrote, Performed, Researched, Published, Won, Earned, Selected, Negotiated.
Verbs to avoid (admissions tunes them out): Helped, Participated, Was involved in, Worked with, Assisted, Volunteered (without scope), Was a member of, Did, Got.
Ordering matters
Common App ranks the activities in the order you list them. Admissions reads them top-down and assumes #1 is what you care most about. Order them by what matters to YOU — not by how impressive each line sounds.
Your spike (whatever it is) goes #1. Your second-strongest commitment goes #2. Paid work or family responsibilities go in the top half — admissions specifically reads down for these because they signal real-life context.
Things to put on the list that students often skip
- Family responsibilities (caring for younger siblings, supporting a parent's small business, translating for grandparents). These are activities. Put them on the list.
- Paid work, even fast-food or retail. Demonstrates time management and is meaningful context.
- Self-directed projects that don't have a club name (your YouTube channel, your novel, your home lab). These count.
- Online communities you genuinely contribute to (Stack Overflow reputation, Reddit moderator, Discord server you run).
Things NOT to put on the list
- One-off events ('attended robotics competition'). Not an activity.
- Inflated involvement (listing yourself as VP of a club where you attended 3 meetings). Counselors may verify; rescissions follow.
- Generic memberships with no engagement (NHS membership without specific actions taken).
- Things you started and abandoned without measurable contribution.
