These essays provide a window into your personality, intellectual curiosity, and fit for the school.

Understanding Supplemental Essays
What Are Supplemental Essays?
In addition to the Common App or Coalition App personal statement, many universities require extra short-answer or long-form essays. These essays help admissions officers evaluate applicants beyond their academic performance.
The purpose of supplemental essays is to give applicants a chance to:
- Highlight personal qualities, experiences, and intellectual interests.
- Demonstrate why they are a strong fit for a specific university.
- Provide additional insights that aren’t covered in the main personal statement.
Why Are They Important?
For competitive universities, where thousands of applicants have strong GPAs and test scores, essays become a key factor in decision-making. They help admissions officers distinguish between students with similar academic credentials. Universities also use these essays to determine if an applicant aligns with their core values, academic programs, and community culture.
While some schools list their supplemental essays as “optional” (e.g., Harvard), in reality, serious applicants should always submit them. A well-written essay can significantly strengthen an application.

Major Updates in College Essays
Each admissions cycle brings changes, and 2025 is no exception. Universities are refining their supplemental essay requirements, making some adjustments that applicants should be aware of.
- Fewer Required Essays: Some universities are reducing the number of mandatory essays or transitioning to shorter response formats.

How This Affects Applicants
With these trends in mind, students must adapt their essay strategies. The key takeaways are:

- Show Intellectual Curiosity: Essays should highlight initiative and depth of thought, rather than simply listing achievements.
Understanding these evolving expectations is crucial for crafting standout essays.

Common Mistakes in Supplemental Essays
Even the most promising applicants can fall into common pitfalls when writing their supplemental essays. Below are some of the biggest mistakes students make—and how to avoid them.
- 🚫 Repeating the personal statement – Supplemental essays should add new insights, not rehash information already covered in the Common App personal statement.
- 🚫 Writing vague or generic responses – Statements like “I love Columbia because NYC is exciting” fail to provide specific, personal reasons why the applicant is a great fit for the school.
- 🚫 Failing to connect with the university’s unique offerings – Strong essays demonstrate a clear understanding of what makes the university special, such as specific professors, programs, or campus culture.
- 🚫 Ignoring word limits or writing overly complex essays – Admissions officers read thousands of applications. Clear, concise, and well-structured responses make a stronger impact.
By avoiding these common mistakes and focusing on authenticity, depth, and specificity, applicants can craft essays that stand out in an increasingly competitive admissions landscape.
How to Craft a Standout Supplemental Essay
Writing a compelling supplemental essay requires more than just answering the prompt. Admissions officers look for essays that showcase depth, self-awareness, and a strong fit for the university. Here are three key strategies to make your essays stand out:
🔹 Deep Research on Each University
One of the biggest mistakes applicants make is writing generic responses that could apply to any school. To avoid this, research the specific programs, professors, and initiatives that genuinely interest you. Instead of saying, “I love Yale for its academic rigor,” mention a specific research lab, faculty member, or course that aligns with your interests. The more specific, the better.
🔹 Show Personality and Self-Awareness
Admissions officers don’t just want a list of achievements—they want to understand who you are. Storytelling can be a powerful tool here. Instead of stating that you’re passionate about literature, share a moment that sparked your love for reading or a book that changed your perspective. However, authenticity is key—avoid exaggeration or writing what you think they want to hear.
🔹 Prioritize Clarity and Structure
A great essay is easy to read and follows a logical progression. Avoid overly complex sentences or unnecessary fluff. Each paragraph should serve a purpose, whether it’s introducing a theme, providing an example, or tying back to your interest in the university. Stick to word limits, and always proofread for clarity and grammar.
By applying these strategies, you can create essays that are both engaging and tailored to each university’s expectations.
Conclusion
Supplemental essays are not just another task in the application process—they are a critical opportunity to stand out in a competitive pool. Universities use them to gain deeper insights into applicants beyond grades and test scores, making them a key factor in admissions decisions.
Each university has its own unique approach to supplemental essays, emphasizing different aspects such as intellectual curiosity, leadership, or personal values. Understanding these differences and tailoring your responses accordingly will significantly strengthen your application.
By conducting thorough research, showcasing personality, and maintaining clear, structured writing, students can craft essays that resonate with admissions committees. Whether you’re applying to Stanford, Harvard, Yale, Princeton, or Columbia, a well-written supplemental essay can make all the difference.
With the right approach, your supplemental essays can become a powerful tool to showcase your strengths and secure admission to your dream university.
