Your student is either back in class this week or heading there next. If they are a senior, the Common App activities section is already open and staring at them. Most families obsess over the personal statement, and fair enough, it is the essay everyone talks about. But the section admissions officers actually read first is the activities section. Ten slots. 150 characters each. That is it.

Why the activities section carries more weight than the essay
Here is the thing. When admissions officers open a Common App, they do not start with the personal statement. They start with the transcript, and then they scan the activities section. Why? Because in about 90 seconds they can see whether the student did anything real over four years of high school.
I tell my students this every fall. Ten strong activity lines can carry your Common App as much as the essay does. Weak ones drag down everything else in the file. That includes the essay, the recs, and the supplementals. If your activities read as filler, the reader is already skeptical by the time they get to your Why Us for Vanderbilt.
The 150-character rule that trips everyone up
You get exactly 150 characters per activity. Ten activities max. That is 1,500 characters, roughly 250 words total, to represent four years of your student’s life outside the classroom.
Trinity, a student we spoke with who was accepted to Harvard for the class of 2027, put it plainly. Most of her friends were writing complete sentences in their Common App and burning through the space. You have 150 characters to boil down four years of experience. If you are not using every character strategically, you are giving away signal.
What admissions officers are actually reading for
They are not reading for a job description. They are reading for evidence. Evidence that the student did something specific, that something changed because of it, and that they can compress that into a single breath. A 150-character line is not a description. It is a story compressed.
When our students at CollegeConsulting.us go through their activities section with their coach, we start with one question. What does this line prove that the resume upload does not? If the answer is nothing, we rewrite it.
The formula: action verb, what you did, result or impact
Here is the formula we teach every student in our program. Action verb. What you did. Result or impact. In that order. Every time.
Before: “Volunteered at local food bank, helped with food distribution.”
After: “Led weekend distribution shift; recruited 8 new volunteers, tripled family sign-ups in six months.”
Same activity. Completely different signal. The first line tells the reader you showed up. The second line tells them you made something happen because you showed up. That is the entire difference between a strong activities section and a forgettable one.
Start with the verb, always
Never open with a title. Never open with “Member of.” The verb is where the reader’s eye goes first, so it needs to earn its spot. Led. Founded. Coached. Designed. Recruited. Coordinated. Pitched. Raised. If your student can’t open with a real action verb, that is usually a sign the activity is filler.
The Princeton Career Development office actually publishes a resume guide we reference often. Their whole framework is the same one we use with our students. Action verb, context, end result. This is not something we made up. It is how professionals write about their own work.
Quantify whenever you honestly can
Numbers do a lot of quiet work inside 150 characters. “Tripled family sign-ups” says more than “significantly increased sign-ups” in half the characters. “Recruited 8 new volunteers” is stronger than “helped bring in more volunteers.” Same information, more signal.
Do not invent numbers. But most students have real ones they never think to include. Hours per week. People led. Dollars raised. Events run. Attendance grown. Sales made. Grade level tutored. If your student did something, there is almost always a number underneath it.
When to skip the formula and let one line do the work
Akshat, another student accepted to Brown for the class of 2027, told us about one of his favorite lines on his own Common App. Four years of Science Olympiad, senior leader in his last year, and “four out of four gold medals at the state level” in his events. That was it. He did not fill the rest of the 150 characters. He left it short and snappy and let the achievement do the talking.
That is a real move, but it only works when the achievement is genuinely strong enough to stand alone in a sea of well-formatted 150-character lines. For 90% of activities, the formula wins. Save the short-and-snappy variant for the one line where the accomplishment is loud enough to earn the whitespace.
The mistakes that quietly kill the activities section
Most families do not lose the activities section because they made a big mistake. They lose it because they made ten small ones, one per line. Here are the ones I see over and over after 16 years and 4,100+ families.
Filler activities in slots 5 through 10
Sai, another Brown 2027 admit we spoke with, said it out loud. His top six or seven activities he could defend cold. Activities eight, nine, and ten were, in his words, “just filler.” Volunteering here. A job there. Cool experiences, but not activities that told his story.
Here is why that is a problem. Every filler slot dilutes the signal from the strong ones. Colleges do not add up your activities. They pattern-match. If your top three lines say “leadership, service, equity” and your bottom four say “I did a lot of random stuff,” the reader loses the pattern. Cut before you fill.
Vague labels instead of specific verbs
“Member of Model UN, all four years.” That line tells the reader nothing they didn’t already know from the fact that Model UN is listed. What did you actually do inside Model UN? Chair a committee? Win an award? Recruit ninth graders? Run the mock crisis simulation? That is the line.
A useful test: if the sentence would still be true if a completely different student wrote it, it is too vague. Rewrite until it could only be true of your student.
Writing full sentences that eat the character budget
Trinity mentioned this too. Her friends were writing complete grammatical sentences, subject and all, and running out of characters halfway through. That is not how the activities section is read. Drop articles. Drop pronouns. Abbreviate where the meaning is obvious. “Mngr” instead of “Manager.” Semicolons instead of “and.” You are writing a compressed line, not a paragraph.
And put your personality in there. Trinity did. Her lines sounded like her, not like a resume writer. That is the difference between a line that reads like an application and a line that reads like a person.
Sequencing: put the story at the top of the list
This is the mistake most families do not even know they are making. The order of your ten activities on the Common App is a signal in itself. Number one is the most weighted. Number ten is barely read.
So the activities that define your student’s story need to be at the top. Not activity number eight. Not activity number nine. If your student’s story is “future doctor who cares about equity in healthcare,” the healthcare research goes at number one, the free clinic volunteering goes at number two, and the equity-focused student group goes at number three. Do not make the admissions officer work to find the story at position seven.
Cluster around a theme, not a category
When Sai got into Brown, the reader looking at his activity list saw two clear traits. Leader. Cares about equity. Sports. Student groups. Chess club. Every activity contributed to one of those two ideas. He was not showing ten different traits. He was showing two, ten different ways.
This is where the Delehey Method™ (Build, Tell, Stack the Deck) shows up in the activities section. The Build phase is the actual doing. The Tell phase is the sequencing. If your student built well but told the story out of order, they are handing the reader a puzzle instead of a picture.
The additional information section is a safety net, not a plan
The Common App gives you an additional information section for exactly this reason. If, after the activities, the honors, and the essay, you feel the story is still not landing, you can use it. But that section is a safety net. Do not treat it as the main event. Ten well-ordered activity lines almost always beat a rambling additional information block.
The weekend exercise every senior should run this week
This is the single most useful hour your student can spend on their Common App this month. It costs nothing. It works whether they are applying Early Decision or Regular Decision. Here is how it goes.
Step one: list every activity, no editing yet
Sit down together. Kitchen table. Laptop open. Have your student list every activity they have done since ninth grade. Sports. Clubs. Jobs. Volunteer work. Self-created projects. Family responsibilities. Everything, in one column, no filter.
Do not sequence it yet. Do not cut it yet. Just list it. You want the raw pile before you start choosing.
Step two: rewrite each one using the formula, out loud
For each activity, rewrite the line using the formula: action verb, what you did, result or impact. Then read it out loud. If it still sounds like resume filler, it is not done. Rewrite again. Cut articles. Add a number. Sharpen the verb.
Reading out loud is not optional. Something about hearing the line makes vague phrasing impossible to miss. Try it. You will catch things your eye slides past.
Step three: rank, cut, and sequence toward the story
Now pick the ten strongest. If your student did fifteen activities, five have to go. That is normal. It is often the right call. Better to lead with ten strong lines than dilute ten with five weak ones.
Then order them so the top three make the story obvious. If a stranger reads only your top three activities, can they tell you what your student cares about? If not, reorder until they can. Different is greater than difficult, but only if the reader can see the pattern.
Frequently asked questions about the Common App activities section
How many activities do I need on the Common App?
You can list up to ten, but you do not have to use all ten. It is better to submit seven strong activities than ten with three filler lines that dilute the rest.
Do the 150 characters include spaces?
Yes. Spaces, punctuation, and abbreviations all count against the 150. That is why most students end up dropping articles and using semicolons.
Can I use abbreviations in the activities section?
Yes, and you should when meaning is obvious. “Mngr” for manager, “VP” for vice president, “hrs/wk” for hours per week. Reserve full spelling for anything a reader might not recognize.
What order should I put my activities in on the Common App?
Order by importance to your story, not chronologically. Your most impactful, most on-story activities go in slots one through three. Slot ten gets the weakest one you kept.
Should I list family responsibilities like caring for siblings?
Yes. Family responsibility counts as an activity, and admissions officers read it as one. Use the same formula. Action verb, what you did, result or impact.
What if my student only has five real activities?
Then list five. Do not invent filler to fill space. Five strong, on-story activity lines will always outperform ten with padding. Colleges read for signal, not volume.
Ten lines can move the needle more than you think
The activities section is the most efficient tool in the entire Common App. Ten lines. 1,500 characters total. And a chance to show an admissions officer exactly who your student is and what they have actually done, before they even reach the personal statement.
Most families spend the fall stressing over the essay and treating the activities section like an intake form. That is backwards. Fix the ten lines first, and everything downstream, essay, supplementals, recs, gets easier because the story is already clear.
If your student is a senior sitting in front of ten empty activity boxes right now, do the weekend exercise. Take every activity on the list. Rewrite each one using the formula. Read them out loud. Then order them so the story shows up at the top.
