The Additional Information section: when to use it, when to leave it blank

The Additional Information section is the Common App field most students misuse. It looks like a free 650 words of extra space, so applicants treat it like a second essay. Then AOs open the application, see a wall of text, and read it as "this kid did not know when to stop."

The truth is that Additional Info is a pressure valve, not a stage. Use it when something in the rest of the application needs context the application itself cannot give. Otherwise, leave it blank. AOs never penalize an empty Additional Info field. They notice a long one.

Three reasons to actually use it

1. Explain a real disruption

If your transcript has a dip in junior year because of a family medical situation, an extended illness, a move, or another disruption, AOs want to know. They are reading a transcript and trying to figure out whether the trend means something about you or whether something happened. Tell them.

Keep it short. Three or four sentences. State what happened, when it happened, what the impact was, and how things are now. Do not ask for sympathy. Do not narrate the emotional arc. Just give them the context so they can read the rest of your application correctly.

2. Add context to an activity that does not fit elsewhere

The Common App activities section gives you 50 characters for the position and 150 for the description. Sometimes that is not enough room to explain the actual scope of what you did. If you ran a research project for a year, started a small business, or built something that needs more context than 150 characters allows, Additional Info is fine for that.

The key is that the entry has to be meaningfully under-described in the activities section, not just under-bragged. AOs can tell the difference.

3. Provide context for a unique circumstance

If you are the first person in your family to apply to college, if you work 25+ hours a week to support your household, if you commute three hours a day to school, if you are a primary caretaker, those are circumstances that change how the rest of your application should be read. AOs want to know. Most students with these circumstances under-tell rather than over-tell.

Three reasons NOT to use it

1. To add a second essay

This is the most common mistake. You finished your Common App essay, you liked another draft you wrote, and you want to share it. Do not. AOs read this as a signal that you cannot prioritize what is most important.

2. To add an "explanation" for a regular bad grade

A C in junior year because the class was hard is not Additional Info material. AOs see thousands of transcripts. They have a sense of how hard each class is at your school. Trying to talk your way out of one bad grade reads as defensive.

The exception is if there is a real disruption (see above) AND a grade dip. Then the disruption is the point, not the grade.

3. To list more activities

If your activities section has ten slots and you used eight, you have two more activity slots. Use them. Do not put activities in Additional Info. The Common App built that field for a reason. AOs check the activity slots; they are not as careful when scanning Additional Info.

How to write it if you are using it

Three to five short paragraphs, max. Plain language. No transitions, no narrative arc. Just the facts the AO needs to read the rest of your application correctly.

A good Additional Info reads like a footnote. A bad one reads like a personal essay sequel.

A word on the COVID-specific question

For applicants who were affected by remote learning, school closures, or the pandemic in ways that changed their academic record, the Common App provides a separate field. Use that for COVID context, not Additional Info. AOs are specifically looking there.

What to do next

Look at your application as a whole. Is there anything in your transcript or activities that needs context to be read correctly? If yes, draft three to four sentences. If no, leave Additional Info blank. The blank version is better than a forced one.

If the rest of your application is locked, the next step is your supplement strategy. That is where most cycles are won or lost.
