Mental Health on Your College Application

Mental Health on Your College Application

You do not have to mention mental health on a college application. If it left a mark a reader will see, such as a grade drop, a medical leave or a missing semester, explain the effect and the dates in 250 words or fewer. You do not need to name a diagnosis.

The decision is yours, but that alone doesn't help you make it. This page gives you the rules that apply, a four-question test, and two short notes you can model. When your note is drafted, you can run it through the free Additional Information review.

Every Common App, college and government page quoted below was checked on October 30, 2026. The Common App text comes from its 2026-27 first-year application PDF. The live form controls, so read the question in your own account before you submit.

What the application and the law actually say

Three sources settle most of the question. None of them requires you to disclose anything.

Common App names mental health directly. The "Challenges and circumstances" question in the 2026-27 first-year application opens: "Sometimes a student's application and achievements may be impacted by challenges or other circumstances." Its list includes "Physical health and mental well-being". It then says:

"If you're comfortable sharing, this information can help colleges better understand the context of your application. Colleges may use this information to provide you and your fellow students with support and resources. … Max word count: 250"

The second box, Additional Information, reads: "You have the option to share any additional details or qualifications not reflected in the application. … Max word count: 300". Common App's 2025-26 announcement (February 27, 2025) set those limits: the old "Community disruption" question became "Challenges and circumstances", and Additional Information was "reduced from 650 to 300 words max."

A college admissions office says it is welcome. USC's admission blog post "Addressing Difficult Topics in Your Application" (November 9, 2017) says that if a diagnosis "helps to explain lower grades or difficulties you encountered in your coursework," then "If you feel comfortable addressing this in your application, you are encouraged to do so." It names "mood disorders" among those challenges and adds: "Discussing this in your application does not negatively impact your consideration for admission". That is USC speaking for USC, not for other colleges.

Federal guidance says disclosure is voluntary. The U.S. Department of Education's Office for Civil Rights guide Students with Disabilities Preparing for Postsecondary Education (revised September 2011) answers two questions:

"May a postsecondary school deny my admission because I have a disability? No. If you meet the essential requirements for admission, a postsecondary school may not deny your admission simply because you have a disability."

"Do I have to inform a postsecondary school that I have a disability? No. But if you want the school to provide an academic adjustment, you must identify yourself as having a disability. … In any event, your disclosure of a disability is always voluntary."

This guide is about disability, and this page does not decide whether a condition counts as one. The practical point: you identify yourself only if you want an academic adjustment. USC's post tells students who may need support to contact its Disability Services and Programs office "once admitted".

The privacy fact. USC's post Utilizing the Additional Information Section (August 18, 2025) warns that "any information a student shares in this section will be sent to every school to which they apply through the Common Application. In addition, the information is not confidential." Every college on your list reads the same words.

Our view: disclose the effect, not the diagnosis

Our view: if your record shows a mark, explain what happened to the record and when. Leave out the diagnosis unless the label itself explains something the reader would otherwise misread.

The basis: Common App's list names a category ("Physical health and mental well-being"), not conditions. USC's guidance is about explaining "lower grades or difficulties". Every college gets the same text, and it is not confidential. What changes how a reader sees your file is the effect, such as six missed weeks of spring term. The name of a condition rarely adds to that, and it is the most private part.

The countercase: some students should name it. Name it if your counselor's letter or school report will already use the term, so your note should match. Name it if your school changed your schedule in a way that only makes sense with the reason, such as a reduced course load. And name it if you want to. USC's 2017 post says "feel free to disclose as much or as little as you want." What is unknown: no college publishes how readers weigh a named condition against a described effect. Anyone who tells you the exact effect on your chances is guessing.

A disclosure decision in four questions

Run these in order. Each one has a pass condition.

1. Is there a visible mark? Look for a grade drop, a withdrawal or incomplete, a missed term, a lighter senior schedule, or an activity you stopped. Pass: you can point to a specific item on your transcript or activity list. If you can't, you can stop here. Leaving both boxes blank is a complete answer. For grade patterns in particular, see how to explain a grade drop on a college application.
2. Is it over, or still going? Pass: you can state the current status in one sentence: you returned full time in April, or a weekly appointment still ends your school day early. Do not promise a recovery you are not sure of.
3. Will your counselor say something too? USC's 2017 post notes that "Letters of recommendation from counselors and teachers can also be a good source of information" about learning differences. Pass: you have asked your counselor what their letter or school report will say, and your note does not contradict it. Letting the counselor carry the whole explanation is also a valid choice.
4. Would you be comfortable with every college reading it? Pass: you would be fine with each college on your list, including the one you care least about, reading the exact text. If not, cut details until you would be, or leave it to the counselor.

If you pass questions 1, 2 and 4, write the note. Question 3 decides how much detail you add.

Where it goes: Challenges and circumstances, Additional Information, or the essay

Common App puts "Physical health and mental well-being" in the Challenges and circumstances list, so that is usually the right box. Don't split one explanation across both boxes. Put the health note in one, and put any separate record fact in the other. For fields beyond health, our guide to what belongs in Common App Additional Information has a full placement table.

Applying to medical school instead? The research and the rules there are different. See mental health disclosure in medical school applications.

Two constructed notes

Two constructed examples, written by us, not real applicant statements. Neither names a diagnosis. Both state the period, the effect on the record and the current status.

Constructed example: a six-week medical leave (65 words)

Constructed example, written by us, not a real applicant statement.

From February 2 to March 13 of my junior year, I took a six-week medical leave. I missed most of the third quarter in all five classes. My school let me finish AP Chemistry pass/fail, which explains the "P" on my transcript. I returned full time on March 16, and my fourth-quarter and senior-year grades reflect my usual work. My counselor can confirm these dates.

Why it works: a reader can match each sentence to the transcript, the "P" is explained, and the note ends on the present.

Constructed example: recurring absences during treatment (64 words)

Constructed example, written by us, not a real applicant statement.

Since September of my senior year, I have had a health appointment every Tuesday and Thursday afternoon, and it continues. I miss sixth and seventh periods on those days. I left orchestra, which met seventh period, and I take AP Statistics, a sixth-period class, through my school's online option. That is why orchestra stops in senior year and AP Statistics is listed as online.

Why it works: it explains two visible things, an activity that ends and an online course, and it gives the current status. It does not describe symptoms, and it does not ask for sympathy.

Both notes use about a quarter of the 250-word limit. Short is not a weakness when the job is to explain the record.

If you write the personal essay about it

The second prompt in Common App's numbered list reads: "The lessons we take from obstacles we encounter can be fundamental to later success. Recount a time when you faced a challenge, setback, or failure. How did it affect you, and what did you learn from the experience?" The personal essay has a 650-word limit, and the application says "650 words is your limit, not your goal."

Our take: write the essay about mental health only if the story is about how you act now, not about the worst month. Keep the hard period to a short part of the essay. Spend the rest on what you do differently today, in the present tense, with specific actions. Two patterns from our list of Common App essay clichés apply here: disclosure with no story beyond the label and the unprocessed trauma account.

The countercase: if the experience is still unfolding, or writing about it is painful, choose another prompt. Put the record facts in the 250-word box. Your personal essay does not have to carry your hardest year.

If the condition is a learning difference or ADHD, see ADHD and learning disabilities on a college application.

Questions about mental health on college applications

Do I have to tell colleges about a mental health condition?

No. Common App's question says "If you're comfortable sharing". The Education Department's OCR guide says disclosure of a disability "is always voluntary." You identify yourself only if you want an academic adjustment.

Can a college reject me for mentioning depression or anxiety?

OCR's guide says a postsecondary school "may not deny your admission simply because you have a disability" if you meet its essential requirements. USC says discussing a diagnosis "does not negatively impact your consideration for admission" at USC. No other college's practice is published in these sources, so we can't tell you more than that.

Is the Additional Information section confidential?

No. USC's admission blog says information shared there "will be sent to every school to which they apply through the Common Application" and "is not confidential."

How long should a mental health explanation be?

The limits are 250 words for Challenges and circumstances and 300 for Additional Information. Both constructed notes on this page are under 70 words. Use the fewest words that explain every visible mark.

Get a free Quick Review of your Additional Information note against GradPilot's Additional Information rubric. It reads whether your note explains a specific part of your record, gives the period and the effect, and stays short and factual. If you are writing the personal essay about it instead, the Common App obstacles prompt rubric reads a prompt 2 draft for an obstacle with real consequences, what you did afterward and how your thinking changed.
