The Common App Essay: What Makes a Great One (and What Kills It)

The Common App essay is 650 words. It's one of the few places in the application where a student gets to speak directly to an admissions officer without a grade or a test score in the way. And yet it's the part most families procrastinate on the longest, agonize over the most, and often handle in ways that genuinely hurt the application.
After working with students on Common App essays for years, we've seen the full range. Here's what separates the essays that actually work from the ones that don't.
What Admissions Officers Are Actually Looking For
Admissions officers read thousands of essays. They can tell within the first paragraph whether an essay is going to be memorable or forgettable, and by memorable we don't mean dramatic or unusual. We mean specific, honest, and written in a voice that sounds like a real person.
What they're looking for isn't the most impressive topic. It's a student who can reflect, who shows self-awareness, and whose voice comes through clearly. An essay about a small, ordinary moment can outperform an essay about a major life event if the ordinary moment is rendered specifically enough and reveals something real about how the student thinks.
The question an admissions officer is implicitly asking is: who is this person, and do I get a clear picture of them from this essay? If the answer is yes, the essay has done its job.
What Makes a Great Essay
It Starts with a Specific Scene, Not a Statement
The best essays tend to open in the middle of something: a specific moment, a concrete detail, a line of dialogue. They don't open with a thesis about the student's character or a broad statement about life.
Specificity is the engine of a good essay. The more concrete and particular the details, the more a reader feels like they're meeting an actual person.
It Has a Clear Point of View
The essay should reveal something about how the student sees the world. Not a moral or a lesson, necessarily, but a genuine perspective. What does this student notice? What matters to them? How do they think about things?
Students who are trying to say what they think colleges want to hear write essays that feel hollow. Students who are writing honestly about something they actually care about, even if it seems small or unconventional, tend to write essays that are much harder to forget.
The Voice Sounds Like the Student
Admissions officers read the rest of the application alongside the essay. If the essay sounds like it was written by a 45-year-old English professor, that's a problem. The essay should sound like a smart, thoughtful, well-spoken 17-year-old, not a polished adult writer.
This doesn't mean the writing should be casual or sloppy. It means the sentences should have the student's actual rhythm in them. The vocabulary should be words the student actually uses.
What Kills an Essay
The Hero Story with No Complexity
Some students write essays about a moment of triumph: they worked hard, they won the championship, they overcame adversity, and they learned that perseverance pays off. These essays aren't wrong, but they tend to be thin. The arc is predictable, the lesson is obvious, and there's no genuine tension or self-reflection in them.
What makes a reader slow down is when a student shows some ambivalence, acknowledges something that didn't go the way they planned, or reflects in a way that's genuinely honest rather than neatly resolved.
Starting Too Broad
Openings about the world, about life, about the general importance of something before the student has introduced themselves are the most common way essays fail in the first paragraph. The reader doesn't know who you are yet. Start with something particular, and let the bigger idea emerge from it.
Over-Editing Until the Voice Is Gone
Some essays go through so many revision rounds, often with well-meaning parents, teachers, or tutors who all have their own voices, that by the final draft the student's actual voice has been edited out. The essay is grammatically clean and logically organized and sounds like it was written by a committee.
The goal of editing is to make the essay clearer and more like the student, not more polished in an abstract sense.
Trying to Cover Too Much
650 words is not enough space to tell your whole story. Students who try to address multiple themes, activities, or time periods in one essay end up doing justice to none of them. The essays that work best tend to go deep on one specific thing. Depth beats breadth every time.
A Note on the Topic Question
Students often spend a lot of time worrying about which prompt to choose or which topic is "right." In most cases, the topic matters less than the execution. A great writer can make almost any topic work.
Some natural starting points tend to produce stronger essays: moments of genuine surprise or confusion that led somewhere unexpected, relationships that shaped how the student thinks, activities or interests pursued deeply over time, or experiences that revealed something true about who the student is.
How We Help Students Write Essays That Work
At TeachAnew, our Common App essay coaching starts with helping the student find the right story, not assigning one. We ask questions, look for the moments that reveal something real, and then help the student develop it in a way that's genuinely theirs.
We give specific, honest feedback at each stage and help students through the revision process without erasing their voice. The result is an essay that sounds like them and says something true about who they are.
