The University of Illinois Urbana-Champaign is one of the top public universities in the entire United States. Top-ranked computer science, engineering, and business programs, in particular, attract an endless stream of high-caliber applicants from around the globe. Great grades and test scores will put aspiring members of the Fighting Illini on strong footing. However, you are also required to address two or three UIUC supplemental essay prompts.

In addition to our blog on How to Get Into the University of Illinois Urbana-Champaign: Admissions Data and Strategies, head to College Transitions Gateway for all our best free tools and resources, including an admissions calculator for 170+ institutions, college planning guides & templates, and example essays from accepted students.
First, understand how UIUC actually admits students
No university’s headline acceptance rate misleads more than Illinois’. In the most recent completed cycle, UIUC admitted roughly 36.6% of applicants, about 30,400 offers out of a record 83,000-plus applications, down sharply from 42.4% the year before. Applications have more than doubled inside a decade.
Ignore that number. UIUC admits directly by first-choice college and major, and the spread between doors is arguably the widest in American public admissions. Computer science within the Grainger College of Engineering has run in the neighborhood of 7%, comparable to the Ivy League. Grainger as a whole sits near 21%. Gies Business holds its own tight gate. Meanwhile, less impacted colleges admit well above half their applicants. Your real acceptance rate is your major’s acceptance rate.
This is why every one of the essays below is about your major rather than about you in the abstract. UIUC is not asking who you are. It is asking whether you belong in a specific department, and it is asking twice.
A few other things worth knowing before you write:
- UIUC is test-optional, with just over half of enrolling students submitting scores.
- The university recalculates your GPA on an unweighted scale using core academic courses only. Recent admitted students have clustered between roughly 3.65 and 4.0 on that recalculated basis.
- UIUC publishes no separate Early Action and Regular Decision admit rates.
- The application opens September 1, later than the August 1 Common App opening most schools follow, so don’t panic if you cannot find the UIUC questions in early August.
The 2026-27 UIUC supplemental essays
UIUC has published its 2026-27 prompts, and the wording is unchanged from last cycle. Two important notes:
- You will be writing two or three essays, depending on which category you fall into.
- Each response is a maximum of 150 words.
UIUC Supplemental Essays – Applicants to a Major
Applying to a specific major at UIUC? You’ll need to respond to the following two prompts:
Prompt 1
Explain, in detail, an experience you’ve had in the past 3 to 4 years related to your first-choice major. This can be an experience from an extracurricular activity, in a class you’ve taken, or through something else. (150 words)
Before you begin writing, you’ll want to do some brainstorming. Make a list of all experiences from the past three to four years that illustrate your passion and commitment to your first-choice major. Of those, which is most representative of your unique interests?
UIUC is not necessarily asking you to write about the in-class or extracurricular experience that led to you earning the most prestigious awards or holding the highest position of leadership. Instead, pick the option that will allow you to deliver the most memorable and authentic story to the admissions reader.
Note two constraints in the wording. “In detail” means one experience, not a survey of three. And “the past 3 to 4 years” rules out the childhood origin story, which is where a surprising number of applicants spend their opening sentences. Start inside the experience and stay there.
Prompt 2
Describe your personal and/or career goals after graduating from UIUC and how your selected first-choice major will help you achieve them. (150 words)
This prompt shares some of the same elements of a traditional “Why Us?” essay, but UIUC is particularly interested in hearing about why the curriculum in your desired academic department is attractive to you. Below are some quick tips:
- Cite specific academic programs, professors, research opportunities, internship or externship programs, study abroad programs, and student-run organizations.
- State why your chosen program is the perfect fit for you and why you are the perfect fit for it.
- Offer insight into your future personal, academic, and career goals. It’s okay if you’re not 100% sure what you want to do at age 25. Most teens are not. Feel free to speculate based on your current mindset and interests.
In summary, dedicate time to researching your prospective college and department and what makes it truly world-class. The more specific you can get here, the better your UIUC essays will be. Given that Illinois admits by major, a response that would work for any large public university is a wasted opportunity in a way it would not be elsewhere.
UIUC Supplemental Essays – Applicants to the Undeclared Program
Applying undeclared through the Division of Exploratory Studies? (Note that this division was formerly called the Division of General Studies, so older guides may use that name.) You’ll need to respond to the following two prompts instead:
Prompt 1
What are your academic interests? Please include 2-3 majors you’re considering at Illinois and why. (150 words)
We recommend focusing the bulk of your response on the specific academic interests that relate to your possible majors. Whether it’s a general love for math, science, or literature, or a specific interest in aerospace engineering or an obsession with 19th-century French novels, use this opportunity to share what makes you tick, the ideas that keep you up at night, and what subject inspires you to dream big. Whether it’s falling down a Wikipedia rabbit hole about the nature of time or consuming thousands of hours of podcasts on game theory, this is a chance to illustrate the ways in which you are an obsessive learner with an endless thirst for information. The admissions reader should emerge with the sense that you are a sincerely curious young person with a strong intellectual drive.
Finally, be sure to connect these interests to two or three majors at Illinois and support your reasoning with school-specific offerings and resources, like academic departments, courses, and research initiatives. Note that the prompt asks for two or three, not one and not five. Choosing majors that share a thread makes for a far more coherent 150 words than three unrelated fields.
Prompt 2
What are your future academic or career goals? You may include courses you took in high school and how these impacted your goals. (150 words)
Note that this question is a bit different than the one asked of students with a firm first-choice major. Still, we recommend providing as straightforward an answer as possible. Although you may not have a firm idea of your academic goals if you are undeclared, you can use your current academic interests, the ones explored in the question above, as well as past academic experiences to guide your answer. Similarly, if your career intentions are relatively unformed, use this space to share academic or career areas that may be of interest. Don’t sweat it if your plans are still in a nascent stage. This is normal for a 17 or 18-year-old, and UIUC will understand.
The prompt explicitly invites your high school coursework, so use it as evidence. Name the one class that moved your thinking and say what changed, rather than recapping your transcript. Applying undeclared does not mean you have no direction, and this is the sentence that proves it.
UIUC Supplemental Essays – Second-Choice Major
You have selected a second-choice major. Please explain your interest in that major or your overall academic or career goals. (150 words)
If you select a second-choice major on UIUC’s application, you’ll also respond to this third prompt. Follow the advice for the first-choice essays; you are essentially repeating the process for a different field. However, you probably don’t want two completely unrelated majors or career goals. If your first choice was business and your second choice was economics, the relationship explains itself. If the fields are more disparate, say Dance and Chemical Engineering, be sure to provide a thorough explanation.
Now the part most applicants get wrong. At a university that admits by major, the second choice is not a formality. It is the safety valve, and it is frequently the door you actually walk through. If your first choice is computer science, where the admit rate runs near 7%, your second choice is doing most of the work in your application. Two practical consequences:
- Choose a genuinely less impacted second choice. Naming two of the most competitive programs at Illinois wastes the mechanism entirely.
- Choose one you would actually attend. Transferring internally at UIUC, particularly into Grainger computer science, is extremely competitive and never guaranteed. Do not treat the second choice as a foot in the door.
And write it with real effort. An answer that reads as an afterthought tells the committee you would rather not be there, which is not the impression you want attached to the major most likely to admit you.
UIUC’s optional prompts
Two additional prompts appear in the UIUC application, each allowing up to 300 words. Both are genuinely optional and both exist for context rather than for more accomplishments.
Explain any challenges you have faced throughout your academic career, including the dates or timeline below. (300 words)
If you have a low grade or a drop in grades that you have not already explained, do so below. (300 words)
Use these if a specific circumstance affected your academic record: an illness, a family situation, a school change, a stretch where you were working significant hours. UIUC asks for dates and a timeline on the first one, which tells you the register they want. Be factual and specific rather than reflective. Explain what happened, when, and what changed afterward.
If nothing applies to you, skip both. Using them to restate accomplishments already visible elsewhere reads as padding. For a fuller discussion of when optional prompts are worth completing, see our blog on Should I Complete Optional College Essays?.
How important are the essays at UIUC?
UIUC only labels two factors as being “very important” to the admissions process. Those factors are the rigor of your high school coursework and your GPA. The essays are “important” to the application review, rated as equal in importance to test scores, extracurricular activities, and talent/ability.
Consider what that means alongside everything above. Both of the factors UIUC weighs most heavily are fixed by the time you apply. The university is test-optional, so for roughly half of applicants that factor drops out of the file entirely. And because Illinois admits by major, these 300 to 450 words are the only place you make the case for the specific department you want. Very few schools ask for so little writing and give it so much to do.
