Your Life in 150 Characters: The Common App activities section.

You've spent years doing things you care about — leading, building, practicing, showing up. And now the Common App is asking you to describe each one in 150 characters.

That's about 25-30 words. Total.

So, each word must count (*wink*). Don't wait until the last minute thinking you can throw something in. Craft these the way you would your essays. Here's how.

A Few Things Worth Knowing First

Remember, admissions committees review your application holistically — so should you. Your activities section should contribute to a consistent picture of who you are and a strategic story about where you're headed. Are you a student leader? Service-minded? The person who quietly builds things behind the scenes? Are you a future math major or environmental scientist? You don't need all ten activities to point in the same direction, but when an admissions reader finishes scanning your list, they should start to see a person taking shape.

Along with only 150 characters, you only get 10 activities. If you're agonizing over what to leave off, think about what that limit is telling you: admissions committees care about depth more than breadth. Deep involvement with a handful of activities shows commitment and maturity. A long list of titles? Admissions readers see right through that.

Uncommon activities are harder to squeeze in. If you were the president of National Honor Society, the description almost writes itself. But if you spent your weekends building free Little Libraries for underserved neighborhoods? You're going to need every one of those 150 characters just to explain what the activity is, let alone what you did. That's a real challenge, and we'll get to strategies for it below.

A Quick Note on Order

The Common App asks you to rank your activities by importance to you, and they mean it. But "most important" doesn't mean "most impressive sounding." Your first activities should show where you had the biggest impact, what was most interesting to you, where you stood out. Think about it from the reader's perspective: Admissions readers see NHS officer on thousands of applications. Managing weekend operations at your family's restaurant? That tells them something about you that almost no other applicant can say. Put that first.

The Basics of a Good Activity Description

Before we look at examples, a few principles:

Lead with what YOU did, not what the organization does. The reader doesn't need a mission statement. They need to see your role.

Use specific numbers when they help. "Tutored peers" is vague. "Tutored 12 students in AP Calc" is a picture.

Cut every word that isn't earning its place. Articles (a, an, the) can go. So can phrases like "helped to" and "was responsible for." Abbreviate where the meaning is obvious — "yrs," "org," "w/" instead of "with."

Don't waste characters on the obvious. If your position says "Captain" and the activity says "Varsity Soccer," you don't need to write "Led the team as captain" in the description.

Common Activities: Making the Familiar Specific

These are activities admissions readers see constantly. The trick is to make yours concrete enough that they can picture you doing it — not just anyone.

Varsity Soccer — Captain

Led warmups and drills; organized dinners before away games; helped with subbing strategy during games. 2 yr team MVP; 3 yr All-Conference. (139 characters)

Notice there's no "led the team with passion" or "developed leadership skills." It's all action — small, real things that show how you showed up for your team.

Student Government — Class Treasurer

Tracked spending for 5 events; collected dues; gave budget updates to officers/advisor; helped plan junior prom logistics; built budgeting app w/ AI. (149 characters)

This isn't flashy, and that's the point. The reader can see exactly what you did. And that last detail — building a budgeting app — shows initiative without inflating the role. But, don't inflate a bookkeeping role into a finance internship. Honest and specific always beats impressive and fake.

Part-Time Job — Barista, Black Rock Coffee Bar

Trained on espresso, register, and closing procedures; opened shop independently on weekend mornings; handled morning rush solo during staffing gaps. (150 characters)

The hours and weeks are captured in separate fields on the Common App, so don't waste characters repeating them here. Use that space to show what you actually did.

Volunteer Tutoring — National Honor Society

Tutored 3-4 students in algebra & geometry; helped with homework and test prep; focused on organization and study skills to encourage self-sufficiency (150 characters)

The description shows what you did, but that last detail — encourage self-sufficiency — shows how you think. (Notice there's no period at the end; it would put you over 150 characters. Fine to leave it off.)

Debate Team — Varsity Member

Competed in Lincoln-Douglas at 14 tournaments; state quarterfinals; cases focused on environmental policy; researched & wrote all independently (143 characters)

Short, factual, and "wrote all independently" tells the reader something about how you work. But notice the case topic — if this student is applying as an environmental science major, this activity shows exceptional interest in the field. That's the consistent picture working for you.

Uncommon Activities: Making Something Different Easy to Understand

Neighborhood Seed Library — Founder

Built and installed 5 free seed-sharing stations in food deserts; stocked with seasonal vegetable seeds; 200+ families participating after 2 years. (149 characters)

You need the reader to understand the concept and see the impact. "Free seed-sharing stations in food deserts" does both quickly.

Vintage Pinball Restoration — Independent

Restore 1970s-80s pinball machines; source original parts, rebuild circuit boards, refinish cabinets; sold 4 machines, donated 2 to youth centers. (149 characters)

"Independent" as the position signals this is self-driven. The description lets the reader see the skill (electrical, mechanical, aesthetic) without listing them as abstract qualities.

ASL Storytelling YouTube Channel — Creator

Created weekly ASL storytelling videos translating children's books; 2,300 subscribers; partnered with 3 deaf education programs for content feedback. (150 characters)

Every word is doing double duty here — it tells you what the channel is, who it serves, how big it's gotten, and that it's connected to a real community.

Family Restaurant — No formal title

Worked weekend shifts at a family-owned Salvadoran restaurant; built customer engagement through daily social media posts and interaction with comments (149 characters)

"No formal title" is honest and totally fine. The description makes clear this isn't just helping out — it's real responsibility.

One Last Thing

Getting to 150 characters — the best 150 characters — will take several revisions.

Start early. You want time to revisit your descriptions as the rest of your application develops. And ask for help. Sometimes an outsider can see what your experiences say about you before you can see it yourself. (213 characters)

Start early so you can revisit your activities as your application develops. Ask for help. Sometimes an outsider can see things that you missed. (145 characters)
