How to Describe Activities on the Common App

You get 150 characters to describe each activity on the Common App. That is roughly the length of this sentence and the previous one combined. Most students waste those characters on vague descriptions that could belong to anyone. Here is how to make yours specific, compelling, and clear to an admissions officer who will spend about eight seconds reading each one.

The 150-Character Constraint

The Common App gives you 10 activity slots. Each has a position/leadership title (50 characters), an organization name (100 characters), and a description (150 characters). Here is what 150 characters looks like in practice:

"Led weekly coding workshops for 40+ students; built school's first CS curriculum; 3 students placed at national hackathon. Grew club from 5 to 62 members."

That is 154 characters. You are working at exactly that scale. Every word has to earn its place.

How to Order Your Activities

The order of your 10 slots matters. Admissions officers read top to bottom, and attention fades as they go. Your first 3-4 activities set the tone for how they read the rest.

Order by significance, not category. The Common App lets you tag each activity with a type (athletics, community service, etc.), but the order should reflect what matters most to you and your application story. Put your spike activities first.

1. Lead with depth over breadth. An activity you did for 4 years with increasing responsibility ranks above one you did for a semester, even if the semester activity sounds more impressive on paper.
2. Group related activities together. If your story is "aspiring biomedical engineer," put your research, science olympiad, and hospital volunteering in a cluster so the reader sees a through-line.
3. Push generic entries to the bottom. National Honor Society membership with no active role goes in slot 8, 9, or 10.
4. Include paid work if relevant. Admissions officers respect students who work. A part-time job, especially one with responsibilities, belongs on the list.

Writing Descriptions That Land

Start With Action Verbs

Weak descriptions start with "I" or "Helped with." Strong descriptions start with a verb that shows exactly what you did. Here are verbs that work, organized by what you're describing:

Quantify Everything

Numbers are the fastest way to communicate scale. Compare these two descriptions:

Before: "Organized community service events and helped raise money for local charities."

After: "Organized 12 service events reaching 300+ participants; raised $8,400 for three local shelters over two years."

The second version tells you exactly what happened. The first could describe anything from a bake sale to a city-wide initiative.

When quantifying, look for:

• People impacted, served, taught, or reached
• Money raised, managed, or saved
• Growth percentages (membership, viewership, revenue)
• Competition placements or rankings
• Hours per week (if the commitment is substantial)
• Outputs created (articles published, apps built, events run)

Cut Filler Ruthlessly

At 150 characters, every word that doesn't add information is stealing space. Cut "Helped to" (just use the verb), "Was responsible for" (replace with the action), "Various" (be specific or cut), "In order to" (replace with "to"), and "Successfully" (the result speaks for itself).

Before and After Examples

Debate (Before): "Participated in debate competitions and helped organize school debate events. Was a member for three years."

Debate (After): "Competed in 15+ tournaments across 3 years; reached national quarterfinals; organized school's first inter-city debate league (8 schools, 120 students)."

Research (Before): "Worked in a biology lab at the local university doing research on genetics."

Research (After): "Co-authored published paper on CRISPR gene editing in plant cells; 200+ lab hours; presented findings at National Biology Symposium."

Community Service (Before): "Volunteered at the local hospital helping patients and supporting nurses."

Community Service (After): "Volunteered 400+ hrs in ER and pediatric wards; trained 15 new volunteers; created patient intake checklist adopted hospital-wide."

Translating Non-US Activities

This is where international students often lose ground. You did impressive things, but the names and structures don't map neatly to what American admissions officers recognize. Your job is to translate, not explain.

Common translations

Three rules for translation

1. Name the scale. "School sports captain" means very different things at a school of 200 versus 2,000. Include the number.
2. Name the system. If your country's science olympiad selects the top 50 students nationally from 10,000 applicants, say "Selected top 50 from 10,000 nationally." The admissions officer doesn't know your country's selection process.
3. Drop local acronyms. NYSC, NCC, JEE, KCSE: none of these mean anything to an American reader without context. Spell it out or describe what it is.

Telling a Story Across All 10 Slots

Your activity list is not 10 separate entries. Read top to bottom, it should answer one question: "What does this student care about, and how deeply?"

The strongest lists show 2-3 clear themes. If your list looks scattered (debate, basketball, cooking club, hospital, random nonprofit), admissions officers can't build a narrative around you. Your top 4-5 activities should reinforce a clear direction.

Intl2US's Activity Optimizer helps you prioritize for impact, not just pad a list. It identifies which activities reinforce your spike and suggests how to frame each one for maximum clarity.

Final Checklist Before You Submit

Before you lock in your activity descriptions, run through this:

• Every description starts with a strong action verb
• Every description contains at least one number
• No description wastes characters on filler words
• Activities are ordered by significance, not alphabetically or by category
• Non-US activities are translated into terms any American reader would understand
• Your top 4-5 activities tell a coherent story about your interests and strengths
• You have used all 10 slots (even paid work, family responsibilities, and personal projects count)
• Descriptions are under 150 characters (the Common App will hard-cut anything over the limit)
