How to Fill Out the Common App: Section-by-Section Walkthrough

You opened the Common App last week, picked a username, got two screens in, and realized you have no idea what most of these fields want. That is normal. The Common App is dense, the language is bureaucratic, and a lot of the fields do not explain themselves.

This guide walks through every section in the order you will fill them out, and tells you what each field is asking for in plain language. Most of the work is paperwork. Four places trip students up every year, and we will flag those as we hit them.

If you also need the broader application timeline (when to take which test, when to draft essays, what to do in junior summer), our how-to-apply-to-college guide covers that. This article zooms into the platform itself.

The Sections at a Glance

Before you start typing, here is the map of what the Common App contains. Six sections are required for every applicant. Two are conditional. The rest depends on the schools you add to your list.

Plan to spend a full afternoon on the first pass and several follow-up sessions on Activities and Writing. The form is not designed to be done in one sitting.

Setting Up Your Account

Create your account in the summer before senior year, ideally July or August. The Common App opens August 1 each cycle for the upcoming year. Starting early gives you breathing room and lets you complete the static fields (Profile, Family, Education) before school gets busy.

• Use a personal email address you will check for the next year. Not a school email (you lose access after graduation), not a parent's email.

• Pick a password you can remember and write it down somewhere physical. Account lockouts are the most common stress moment in October.

• The platform got a new look this cycle. Navigation lives in a left panel now, and the section formerly called 'Common App' is called 'My Common Application'.

After name and email, the platform asks a few profile questions to set up your account. You then land on a dashboard that shows your sections and their completion status. You can save and exit anytime; the form keeps your progress.

The Profile Section

Profile is mostly basic biographical information: name, address, contact, demographics, language. Two fields trip students up.

Citizenship: The 2026 cycle expanded the options. 'U.S. Permanent Resident' now includes 'Green Card Holder' as a clearer label. There is a new 'U.S. Resident' option. DACA, refugee, asylum-seeker, and undocumented students have clearer paths to identify themselves.

If your status is anything other than 'U.S. Citizen,' read the dropdown carefully. Picking the wrong one can affect financial aid eligibility.

Languages spoken at home: Multilingual students sometimes underreport, listing only English because the form asks for 'first language.' If you grew up speaking Spanish, Korean, Arabic, Portuguese, or any other language at home, list it.

Multilingualism is an asset that admissions readers value, and it informs how counselors see your file.

Demographics: every field here is optional except U.S. military service status. The race / ethnicity question can be skipped if you prefer not to answer.

Address: list every place you have lived since age 14 if the form asks. Skip childhood addresses unless directly relevant.

The Family Section

Family asks about parents or guardians: their education, employment, occupation, and (if they attended college) which colleges they went to.

The hardest field for many students is parent education level. If your parent did not graduate from high school, the form has options for that.

Pick the highest level completed and move on. If your parent graduated from college, list the college name. The form has a dropdown for U.S. colleges and a free-text option for international ones.

If you are a first-generation college student (neither parent has a four-year college degree), the Common App captures that automatically based on your answers. Many schools have specific support programs for first-gen students, and admissions readers see this status.

If you have older siblings who attended or are attending college, list their schools. Some smaller liberal arts colleges track this for legacy interest, but for most schools it is informational.

Parent employment status: pick the one that fits. 'Unemployed' is fine if a parent is between jobs. 'Self-employed' works for someone running a small business. 'Deceased' is the option if a parent has passed away (no other context required).

The Education Section

This is where you enter your high school information, GPA, class rank (if your school ranks), and the courses you have taken or plan to take.

High school information. Enter your school name as it appears in the dropdown. The Common App has a database of every U.S. high school. If your school is not listed, you can add it manually, but check spelling and city carefully.

GPA. Enter exactly what your transcript says. If your school reports both weighted and unweighted, enter both with the correct labels.

Do not round, do not convert, do not 'translate' your GPA into a 4.0 scale if your school uses a different one. The Common App has fields for percentage scales, 5.0 scales, and other systems.

Class rank. If your school does not rank, leave it blank. Many high schools have stopped ranking, and this is normal. If the form requires an answer, pick 'Not ranked' or use the 'decline to state' option.

Current and past coursework. List senior-year courses including any AP, IB, dual enrollment, or honors classes. Match your transcript labels exactly. The Common App has standard course categories for the dropdown.

Should You Submit Test Scores?

The Testing section is optional in the sense that you decide what to submit. About 80% of U.S. four-year colleges still allow some form of test-optional admission. Whether to submit comes down to one question: does your score help or hurt your application at this specific school?

Where to find each school's mid-50%: the school's own admissions page or its Common Data Set Section C9 (a federal report most schools publish). Search 'CDS [school name]' to find it. Decision is per school, not blanket.

The Common App lets you choose for each college separately at submission. Self-reported scores get hidden for schools where you opt out.

The 2026 update: ACT Science is now optional for online test-takers. If you took the ACT and skipped Science, that does not disqualify your score. If your scores are still climbing, our SAT prep guide covers the test calendar and prep strategy.

The Activities Section

Activities is where most students spend the most time. You have up to 10 slots. You do not need to fill all 10. Six well-described activities will read better than ten thin ones.

Each activity slot has four fields:

• Position / Leadership (50 characters)

• Organization name (100 characters)

• Hours per week and weeks per year

• Description (150 characters)

The 150-character description is the field students agonize over. Use action verbs, be specific, include numbers when you can, and do not waste characters repeating what is in the position field.

Order matters. Put the activities most important to you first. Admissions readers look at your top 4-5 most carefully. The list is not chronological. The activity that says the most about you goes first.

The 2026 update: there is a new required short-answer question called Responsibilities and Circumstances. It asks you to describe family obligations or other significant responsibilities that have shaped your time outside school.

This is where caregiving for siblings, working to support your family, managing a chronic illness, or any major non-traditional commitment goes. Keep it factual. This is reporting, not narrative.

The Writing Section

Writing has two parts: the personal statement (650-word essay sent to every school) and the Additional Information field (a separate, optional space for context).

The personal statement is the main essay. Seven prompts. Same prompts as recent cycles. Pick one, write the essay, paste it in, save. Most students draft this in summer and revise through October. Our Common App essay guide covers prompt selection and revision strategy.

The 2026 change worth knowing: the Additional Information section limit dropped from 650 words to 300 words. If you are using older guidance that says you have 650 words, that is no longer accurate. Adjust accordingly.

Use the Additional Information section only if you have something specific that does not fit elsewhere:

• Explanation of a grade dip (illness, family circumstance)

• Context for a disciplinary action on your record

• A research project or significant work that needs more space than the activities description allows

• Documented learning differences and how you have worked around them

Do not use Additional Information to repeat what is in your essay or activities, brag about achievements that fit in the regular section, or pad out your application. Most students do not need this section. Empty is better than padded.

Courses & Grades (Only If Required)

This section appears in your menu only if at least one school on your list requires it. Schools that commonly require self-reported transcripts: USC, NYU, Stanford, ASU, Penn State, Florida State, Clemson, University of Oregon, University of Wisconsin, University of Massachusetts, Loyola Marymount.

If Courses & Grades is in your menu, plan 30-60 minutes:

• Enter every course you have taken in 9th, 10th, 11th grades plus your senior schedule

• Enter the grade you received exactly as it appears on your transcript

• Use the term system your school uses (semesters, trimesters, quarters)

The information you enter is used to compute a Common App GPA that requesting schools see alongside your official transcript.

Mismatches between what you self-report and what your transcript shows can flag the application for review or, in rare cases, lead to a rescinded admission. Re-read your transcript carefully and copy exactly.

Recommenders and the FERPA Waiver

The Recommenders section asks you to invite the people who will write your letters: your school counselor (always), one to three teachers (depending on school requirements), and optionally an 'other recommender' (an employer, coach, mentor, etc.).

FERPA waiver: always waive. When you waive your FERPA rights, you give up the right to read your recommendation letters after enrollment. Admissions readers trust waived letters more because they know teachers wrote without you looking over their shoulder.

Not waiving is a small red flag that suggests you do not trust your own recommenders. There is no upside to keeping the right.

Inviting a recommender: in My Colleges, find the school, click Recommenders and FERPA, and use the 'Invite Recommender' button. Enter their name and email. They receive a Common App email with submission instructions.

Track each recommender's status (Invited / Started / Submitted) on your dashboard. Best practice: ask teachers in person before sending the digital invite.

Adding Schools and Submitting

The My Colleges section is where you build your school list, fill out school-specific supplements, and pay application fees. Search by name, click to add. Each school gets its own dashboard with its specific deadline, supplements (if any), and fee.

Supplements. Many schools have additional essays beyond the personal statement. Common questions include 'Why this college?', short-answer activities prompts, and 'Why this major?'

Read each supplement carefully before assuming you can copy-paste from another school. Most 'Why this college?' essays should be customized.

Application fees. Typical fees range from $50 to $90. If your family qualifies, you can request a fee waiver during the application.

Federal fee waiver eligibility includes free or reduced-price lunch, family income at or near the federal poverty line, and several other categories. Your counselor confirms eligibility.

Submitting. You submit applications one school at a time, in any order. There is no batch submit. Once you click submit and pay (or waive) the fee, the application is locked for that school.

You cannot edit the personal statement, activities, or any other section for that school after submission. You can update other schools' applications independently.

Pick your round (ED, EA, REA, ED2, RD) per school during submission. Our round selection guide covers when to use each, and our how to choose a college guide walks through narrowing your list before you start adding schools.

Frequently Asked Questions

When should I create my Common App account?

Summer before senior year (July or August). The Common App opens August 1 for the upcoming admissions cycle. Starting early gives you time to complete the static sections before school gets busy.

Do I have to fill out all 10 activity slots?

No. Six strong, specific activities read better than ten thin ones. Quality over quantity. Use only as many slots as you have meaningful activities.

Should I submit test scores to test-optional schools?

Submit if your score is at or above the school's mid-50% range. Skip if your score is below the mid-50%. The decision is per school, not blanket. The Common App lets you choose at submission time for each application.

What if my parents did not graduate from high school?

Pick the highest level completed in the dropdown and move on. The Common App marks you as a first-generation college student automatically based on your answers. Many schools have specific support programs for first-gen students.

Can I edit my Common App after submitting?

You cannot edit the application that has been submitted to a specific school. You can continue updating other applications independently. Each school sees the version you submitted to that school.

Do I need to use the Additional Information section?

Only if you have specific context that does not fit elsewhere: a grade dip, a documented hardship, a research project that needs more room. Empty is fine. Padding the section makes the application weaker, not stronger.

Final Word

Common App is a form. Most of it is paperwork. Four places require thought (Activities, Personal Essay, Additional Information, FERPA / Recommenders), and the rest is data entry.

Take your time on the four, do not overthink the rest, and check your work before clicking submit.
