Staring at a blank Common App activities list with 10 empty slots can feel like its own kind of pressure. We get it. After years of clubs, sports, jobs, and weekend commitments, you have to squeeze your high school self into character-limited boxes that admissions officers will skim in seconds. The good news? With the right approach, this section becomes one of the strongest parts of your application.
The Common App activities section gives you up to 10 slots to describe extracurriculars, jobs, family responsibilities, and personal projects. Each entry has a 50-character position field, 100-character organization field, and 150-character description.
The sections below cover what counts as an activity, how many slots to fill, how to order them, how to write descriptions that catch an admissions reader’s eye, and the mistakes that weaken thousands of applications every year.
What is the Common App Activities Section?
The Common App activities section is where you tell colleges what you do outside of class. You get up to 10 entries, and each one has the same structure: an activity type (chosen from a dropdown like Athletics, Community Service, or Work), a position or leadership description (50 characters), an organization name (100 characters), and a description (150 characters). You’ll also note the grade levels you participated in, whether you did the activity during the school year or summer (or both), hours per week, and weeks per year.
That’s 300 characters total to make each activity land. List activities in order of importance, lead with strong verbs, and quantify your impact whenever possible. It’s tight, but it’s enough when you write with intention.
What counts as an activity?
A lot more than students think. According to the Common App, activities can include arts, athletics, clubs, employment, personal commitments, and other pursuits. That definition is broad on purpose.
Here’s what we routinely see students forget to include:
- Part-time jobs (yes, even retail or food service)
- Family responsibilities (caring for siblings, translating for parents, helping run a family business)
- Self-taught skills and personal projects (coding a website, building a YouTube channel, learning an instrument from scratch)
- Religious or cultural community involvement
- Independent research, summer programs, or online coursework
- Hobbies you’ve stuck with for years (creative writing, photography, gardening, coaching a younger sibling’s team)
If it took your time, energy, and commitment, it counts. Admissions officers want to see how you actually spent your time, not a polished list of stereotypically “impressive” activities.
Should you fill all 10 slots?
You don’t have to. Most strong applicants fill 8 to 10, but the right number for you is the number of activities you genuinely participated in. Padding with thin involvement does more harm than good, because it dilutes the activities that actually matter.
Here’s a simple test: if you can’t write a meaningful description with specifics, that activity probably doesn’t deserve a slot. A reader who sees three vague entries followed by seven detailed ones starts wondering whether everything else is inflated too.
That said, don’t undersell yourself either! Sit down with a parent, friend, or tutor and brainstorm everything you’ve done since 9th grade, including summer commitments, one-time leadership roles, and family responsibilities. You’ll almost always remember more than you initially thought. Then prioritize ruthlessly.
If you’re worried you don’t have “enough” activities because of work, caregiving, or other circumstances, mention that context in the Additional Information section. Admissions officers read your list within the context of your life.
How to order your activities for the biggest impact
Order matters more than most students realize. Admissions officers read activity lists fast, often in under a minute, and their attention concentrates on slots 1 through 5 and slot 10. The middle gets skimmed.
That means three things:
- Lead with your most significant activity, regardless of when it happened. If your strongest commitment was a sustained 9th-through-12th-grade leadership role, that goes first, even if you joined a flashier club senior year.
- Front-load depth, leadership, and impact. Activities where you held a real role, drove results, or stuck with something for years belong in your top 5.
- Use slot 10 strategically. It’s the last thing the reader sees, so put something memorable there. A creative personal project, an unexpected hobby, or a quirky-but-meaningful commitment can leave a stronger final impression than a generic membership.
Don’t order chronologically. Don’t order by hours per week. Order by what matters most to your story.
How to write descriptions that stand out (in 150 characters)
This is where most students leave value on the table. The 150-character description is your one shot to communicate role, action, and impact in a single line. Make every word work.
Use strong verbs. “Led,” “founded,” “designed,” “mentored,” “raised,” “organized,” and “built” tell a reader exactly what you did. “Helped,” “participated,” “involved in,” and “worked on” tell them almost nothing. Action verbs at the front of each line make your descriptions punch.
Quantify whenever possible. Numbers are specific, and specific is memorable. “Raised $3,200 for a local food bank” beats “raised money for charity.” “Tutored 12 middle schoolers weekly” beats “tutored students.” If you led people, organized events, or moved money, say how many and how much.
Use fragments, not full sentences. You don’t need complete sentences here. “Led weekly debate practices, mentored 8 novice debaters, organized regional tournament hosting 60+ students” is far more efficient than the sentence version. Drop articles (“the,” “a”) and pronouns when they don’t add meaning.
Don’t repeat the position or organization fields. If your position is “Captain” and your organization is “Varsity Soccer,” your description shouldn’t say “I was captain of the varsity soccer team.” Use those 150 characters to show what you actually did with that role.
Try the mini-story approach. Former Penn admissions dean Sara Harberson recommends treating each description like a tiny window into your role and intent rather than a resume bullet. Show heart and specificity:
Position: Volunteer Chef
Organization: Shady Creek Shelter
Description: Sundays are for cooking. Mom and I prep meals using the shelter’s garden and family recipes to feed neighbors in need.
Compare that to:
Position: Volunteer
Organization: Local Shelter
Description: Volunteer at local shelter; cook meals; serve and distribute meals; clean up kitchen.
Same activity. Completely different impression.
Common mistakes to avoid
Even strong students fall into these traps. Watch for them in your own draft:
- Repeating yourself across fields. “President of Debate Club” as your position, then “Served as president of debate club” as your description. Wasted space.
- Generic verbs everywhere. Lists full of “helped,” “participated,” and “was involved in” read like a copy-paste job. Vary your verbs and pick specific ones.
- Resume-style semicolon soup. Long strings of clauses separated by semicolons with no punctuation at the end is a tell that signals AI-generated or rushed writing to admissions readers. Mix in periods. Vary your rhythm.
- Padding with weak activities. A 9th-grade club you joined for two months and forgot about isn’t helping. Cut it.
- Stretching the truth. Inflating hours, inventing leadership titles, or claiming roles you didn’t actually have can lead to rescinded acceptances. Counselors confirm details, and inconsistencies between your activities list and recommendation letters surface fast. Be honest.
- Burying your best work. If your most meaningful activity is in slot 7, you’re hiding it from the people who decide your future. Move it up.
- Forgetting to spell out acronyms. Your reader doesn’t know what “FBLA” or “MUN” means without context. Spell out anything that isn’t universally recognized.
When to use the Additional Information section
The Additional Information section is your overflow space, and it’s underused. If a single activity is so multi-dimensional that 150 characters can’t capture it (a self-founded nonprofit, a years-long research project, a complex family caregiving role), use Additional Information to expand. End your activities description with “(see Add’l Info)” so the reader knows where to look.
This space is also where you give context that affects how to read your activities list. This space is the perfect place to list if you are:
- A student who works 25 hours a week to support their family
- A student with a learning difference who balances executive function coaching alongside their other commitments
- A student who took on caregiving responsibilities for a sibling or grandparent
Don’t repeat what’s already in your activities list. Expand on what’s missing.
FAQ
How many characters do I get for each Common App activity description?
You get 150 characters for the description, 50 for the position or leadership field, and 100 for the organization name. That’s 300 characters total per activity, plus structured fields for grade levels, hours per week, and weeks per year.
Do admissions officers really read all 10 activities?
Most spend the bulk of their attention on activities 1 through 5 and the final slot. Middle entries get skimmed quickly. That’s why ordering by importance matters so much, and why slot 10 deserves something memorable.
What if I don’t have a leadership title?
Leadership doesn’t require a title. If you took initiative, organized something, taught a peer, solved a problem, or improved a process, that’s leadership. Describe what you actually did with strong action verbs, and the substance speaks louder than the word “President” ever could.
Should I include a job or family responsibilities?
Absolutely. Paid work, caring for siblings, translating for parents, or contributing to a family business are all legitimate activities. They demonstrate responsibility, time management, and real-world skills that admissions officers value. List them with the same care as any club or sport.
When should I start working on my activities list?
The summer before senior year is ideal. That gives you time to brainstorm thoroughly, draft descriptions, get feedback, and revise without the pressure of essay deadlines piling up. If you’re a junior in Texas, you’ll also want to be thinking about the automatic admissions for UT Austin and Texas A&M and how your activities list fits into your overall application strategy.
Need Help?
Your activities list is more than a checkbox on the application. It’s a window into your high school self, and the students who stand out aren’t always the ones with the longest list of titles. They’re the ones who write with real specificity and let their actual lives come through on the page.
