The fixed limits for 2026–27
The cycle opened on 1 August. Most of a student's answers roll over from last cycle; college-specific answers do not.
| Personal essay | 250–650 words, one of seven prompts (unchanged this year) |
| Activities | Up to 10: position 50 characters (now optional), organisation 100, description 150 |
| Honors | Up to 5, 100 characters each |
| Additional information | Up to 300 words |
| Challenges and circumstances | A yes or no, then up to 250 words |
Each college adds its own questions and writing supplements, with their own limits. Some appear only when a student gives a particular answer, such as choosing a major or an honors college, so they can only be seen inside the student's own application.
Following the application as an advisor
A student can invite up to three advisors, and an independent counsellor is one of the cases the role is meant for. As an advisor you can see the student's college list, deadlines and progress for each college, and a PDF preview of the application if the student allows it. You cannot edit anything, and the colleges are not told you were invited.
Logging in as the student, or using tools that read the Common App automatically, is against its terms of use. Work with what the student shares and what you can see as their advisor.
AI and the student's own work
The Common App's fraud policy counts presenting the substantive output of an AI tool as one's own work as fraud, and every applicant affirms that the application is their own. Some colleges publish their own, stricter rules.
- Use AI to ask questions, point out structure and check limits, not to write sentences the student submits.
- Keep a record of what help was given on each essay. It protects the student and your firm.
- Check each college's own guidance on AI before the student starts its supplements.
Five checks before a student submits
- Is every required supplement for each college written, final and within its limit?
- Has an adapted "why us" essay been checked for another college's name?
- Is the decision plan right for each college, and is the deadline on the calendar?
- Have recommenders been invited, and has each one submitted?
- Does the PDF preview match the final drafts?
Polaris keeps the work beside the Common App
The college list, each prompt with its limit, versioned essays with comments, recommenders and deadlines live in Polaris. Rehnuma asks questions and never writes, every AI comment is logged, and the uploaded PDF preview is checked against the final drafts.
Quick answers.
How long is the Common App personal essay for 2026–27?
Between 250 and 650 words, answering one of seven prompts. The prompts are unchanged from last year.
Can an independent counsellor see a student's Common App?
Yes, as one of up to three advisors the student invites. Advisors see the college list, deadlines, progress and, if the student allows it, a PDF preview. They cannot edit the application.
Can students use AI to write Common App essays?
The Common App's fraud policy treats presenting AI-written content as one's own work as fraud. Use AI for questions and feedback, not for the words the student submits, and check each college's own policy.
