关键发现

1. Common App 禁止的是冒认实质性 AI 产出为本人原创。 必须保留 intentionally misrepresenting、one’s own original work、substantive content or output 的条件，不能缩写成“使用任何 AI 就是申请欺诈”。该文件没有逐项授权语法检查、构思、翻译或改写；这些边界仍须查目标院校。[CA1]
2. 平台后果与大学录取决定不同。 Common App 可暂停、终止账号并向 My Colleges List 通报；大学如何处置录取是另一个层级，不能把平台处分直接等同于必然退学。[CA1]
3. Common App 明文提供申诉机会。 针对平台自身的违规认定，注册用户可以在书面通知后 10 个工作日内提交陈述与证据。这并不保证每所大学都有同样的录取申诉程序，但足以说明不能笼统写“申请审查没有任何陈述或申诉机会”。[CA1-Q2]
4. UC 官方材料区分辅助与代写。 官网招生人员访谈允许谨慎利用 AI 辅助结构、可读性；2025 年招生顾问培训材料承认早期阶段的辅助作用，但要求最后的 PIQ 在声音、实质和反思上属于申请人本人。不能据此理解为可直接提交 AI 改写后的任何内容。[UC1, UC3]
5. UC 也有明确标注 2026–27 申请季的指导。 现场下载的 first-year 申请指南共 84 页，第 67 页将 AI 定位为早期构思/整理思路的工具，而非本人作品与声音的替代。搜索摘要仍可能显示旧版，不应照抄摘要。[UC5]
6. UC 有直接点名生成式 AI 的申请诚信声明。 本轮找到并下载公开官方 Statement of Application Integrity：允许就内容、编辑获得建议，包括用生成式 AI 辅助可读性，但内容和最终文字必须属于本人；UC 可要求核实内容或写作确系本人所作。该正式系统文件比招生访谈更适合作为规则依据。[UC4]

[UC5-Q1]

Can be a useful tool for brainstorming or organizing your thoughts in the early stages, but your final PIQ responses should be your own work and voice

[UC5-Q2]

All applicants must agree to UC’s Statement of Application Integrity when submitting their UC application!

[UC4] Statement of Application Integrity

• 发布单位Publishing unit University of California undergraduate admissions application
• 官方来源Official source https://apply.universityofcalifornia.edu/docs/StatementOfIntegrity.pdf
• 页面日期Page date Last updated August 2023
• 适用范围Scope UC undergraduate application; shared system rule; public PDF page 1
• 来源性质Authority system-application-policy

[UC4-Q1]

The personal insight responses should reflect the student’s own ideas and experiences, be independently written by the student and reflect the student’s personal writing style. Students may receive advice on content and editing, including the use of generative artificial intelligence software to assist with readability, but content and final written text must be their own.

[UC4-Q2]

UC conducts regular screenings to verify the integrity of the responses, may request authentication of the content or writing as the student’s, and will take action when it is determined that the integrity of the response is compromised.

[UC4-Q3]

Students found to have falsified application information will be subject to penalties up to and including denial of admission, withdrawal of an admission offer, registration cancellation, expulsion or revocation of a University of California degree.

[CA1] Common Application Fraud Policy

• 发布单位Publishing unit The Common Application, Inc.
• 官方来源Official source https://www.commonapp.org/fraud-policy/
• 页面日期Page date August 2023 (Date of Last Update)
• 适用范围Scope Common App registered users; platform policy, not an individual university policy
• 来源性质Authority platform-policy

• 提取所用公开数据Public page-data used for extraction https://www.commonapp.org/page-data/fraud-policy/page-data.json

[CA1-Q1]

Submitting plagiarized essays or other written or oral material, or intentionally misrepresenting as one’s own original work: (1) another person’s thoughts, language, ideas, expressions, or experiences or (2) the substantive content or output of an artificial intelligence platform, technology, or algorithm;

[CA1-Q2]

A Registered User who receives notice that Common App has determined a violation of our Terms of Use occurred shall be provided an opportunity to appeal Common App’s decision within ten (10) business days from the date of Common App’s written notice by submitting a written statement and any relevant supporting documentation refuting the Fraud determination or otherwise explaining the circumstances around the misconduct.

[CA1-Q3]

Common App in its sole discretion may take action as a result of a Fraud determination which may include permanent suspension, temporary suspension, or termination of their Common App user account, and disclosure of the Fraud to the Registered User’s “My Colleges List."

[UC1] Shaping your personal narrative: PIQ tips and more from UC admissions experts

• 适用范围Scope UC undergraduate application; system-hosted interview, not a campus-specific rule
• 来源性质Authority official-advice

[UC1-Q1]

First, whatever you ultimately submit better be your own creation.

[UC1-Q2]

That said, an AI tool can help you with structure and readability, but use it with caution.

[UC1-Q3]

Your writing needs to reflect your own experiences, in your own words.

[UC2] Personal insight questions — Applying as a first year

• 发布单位Publishing unit University of California Admissions
• 官方来源Official source https://admission.universityofcalifornia.edu/how-to-apply/applying-as-a-first-year/personal-insight-questions.html
• 页面日期Page date Not stated
• 适用范围Scope UC first-year application PIQs
• 来源性质Authority official-application-instructions

[UC2-Q1]

Your answers should reflect your own ideas and be written by you alone, but others — family, teachers and friends can offer valuable suggestions. Ask advice of whomever you like, but do not plagiarize from sources in print or online and do not use anyone's words, published or unpublished, but your own.

• 发布单位Publishing unit University of California Admissions — 2025 Counselor Conference

• 适用范围Scope UC PIQ counselor training; PDF page 29 of 44
• 来源性质Authority official-counselor-guidance

[UC3-Q1]

If used thoughtfully, AI tools might assist in the early stages of the writing process. But students should ensure that their final PIQ responses are entirely their own in voice, substance, and reflection.

[UC3-Q2]

AI is not a replacement for a student's own words!

Research limits / 适用边界

• 不将 2025 年资料的发布日期改成 2026 年。本次是 2026-09-24 访问到的公开快照；UC1 访谈的页末还保留 fall 2026/2025 deadline，UC3 为 2025 培训材料；与明确标注 2026–27 申请季的 UC5 分开。
• 已取得 UC 官方公开申请诚信声明 PDF（页内标明 2023 年 8 月更新），但未登录申请系统核对当季提交按钮前的最终认证界面。不得把公开 PDF 的访问日期改成它的更新日期，也不能保证其与未来申请季的界面完全一致。
• UC 的三所样本学校可共同受到系统 PIQ 要求约束，但在跨校统计中必须标记 共同来源，不可作为三份相互独立的政策证据。
• 原文提及 plagiarism detection 不等于公布 AI 检测器名称、准确率或“仅凭分数作决定”的程序，不能自行补推。
• 本文件不替代学校或申请平台当季页面；特殊项目、作品集、视频面试和推荐信可能另有要求。

核心结论

1. AI 辅助不等于 AI 代写。 UCAS 指导举例支持主题构思、结构建议、可读性检查，但最终个人陈述应反映申请者自己的经历与表达；页面明确把直接复制 AI 文字作为最终文本列入 Don’t。[UCAS-S1]
2. 保留页面内部的细节，不能简化成“所有起草都禁用”。 同一指南还介绍 Copilot 可由本人笔记生成段落初稿。它是工具示例，不是许可将该段落直接作为最终文书提交；需结合 Don’t 项及本科申请声明阅读。是否符合某校更窄的使用边界，还须单独核查。[UCAS-S1][UCAS-S6]
3. 声明比一般工具介绍更直接关联提交。 本科申请声明要求个人陈述由本人完成；若材料可能来自他人或 AI，UCAS 可通知相关机构与申请院校，由院校决定适当行动。不是每次 AI 辅助都必然取消申请。[UCAS-S6]
4. 相似度检查不等于 AI 检测。 官方 PDF 描述与历年文书及网页样例库的文本比对、人员复核和通知流程；大于 30% 的相似度触发所述人工复核，并不是“30% 以下允许抄袭”或“AI 含量阈值”。[UCAS-S5]
5. 两种程序不能混淆。 UCAS 取消申请有申诉程序，核验 PDF 给出取消后 28 天提交申诉及书面答复安排；而相似度报告 PDF 则称不预期对报告本身存在申诉理由。平台取消的申诉权不能自动外推为对大学录取决定的申诉权。[UCAS-S4][UCAS-S5][UCAS-S6]
6. 英国四校仍分别核查。 UCAS 明确建议查各校的 AI 指导；LSE、Oxford、Cambridge、Imperial 的校方或项目规则见对应学校档案。本补充不是四校统一许可清单。[UCAS-S1]

[UCAS-S1] A guide to using AI and ChatGPT with your personal statement

• 采集时间Acquired 2026-09-26T02:18:51.975021+00:00
• 上下文说明Context Q4 is the object of the page’s Don’t heading. The full source contains brainstorming and structure suggestions, and an explicitly described Copilot paragraph-drafting example; none removes the final authorship/declaration requirement.

UCAS-S1-Q1 — limited support, not outsourced authorship

You could use ChatGPT as a tool to help inspire, clarify and articulate your own ideas, rather than asking it to write your entire personal statement for you.

UCAS-S1-Q2 — readability

ChatGPT can be used to check your personal statement draft for readability. It may suggest ways to rephrase sentences to make them more concise, while maintaining their meaning.

UCAS-S1-Q3 — Copilot example must be read with final-text prohibition

It can create a first draft of a paragraph from a few bullet points from your notes, or summarise your first draft if you're over the character count.

UCAS-S1-Q4 — item under Don’t heading, not permission

Copy and paste from AI tools and use as final text.

UCAS-S1-Q5 — institution-specific guidance

We'd advise researching what individual universities and colleges recommend you include in your personal statement, and whether they have specific guidance around using AI tools like ChatGPT.

[UCAS-S6] UCAS Undergraduate declaration

• 采集时间Acquired 2026-09-26T02:44:26.130674+00:00
• 上下文说明Context Read publicly without entering the application system or accepting the declaration.

UCAS-S6-Q1 — authorship

Your personal statement must be completed by you and we do undertake checks to verify that it is your own work.

UCAS-S6-Q2 — notification; universities decide action

If your personal statement includes material that we reasonably consider may have been copied from or provided by another source, including but not limited to friends, writing service providers or artificial intelligence software, we may notify your current school, college or other UCAS registered centre (provided that, where legally required, we have your permission to share such information) and the universities and colleges to which you have applied, whose decision it will be to take what action they consider appropriate.

UCAS-S6-Q3 — platform cancellation appeal

If we cancel your application you have the right to appeal.

UCAS-S6-Q4 — not university-decision appeal

The appeal process relates only to applicants whose application has been cancelled by us.

UCAS-S4-Q1 — possible cancellation, not mandatory penalty for every AI use

We may cancel applications if false, missing, and/or misleading information is provided.

UCAS-S4-Q2 — appeal timing; page 2

If you decide to submit an appeal, you must do this within 28 days from the date your application was cancelled. We will notify you of our decision in writing within 28 days.

• 采集时间Acquired 2026-09-26T02:44:16.250307+00:00
• 上下文说明Context Five-page PDF. Page 5 explicitly addresses the 2026-cycle change to three answers and says similarity reporting continues. PDF extraction ligatures retained in verbatim quotes.

UCAS-S5-Q1 — text similarity, not AI authorship classification

Each personal statement is compared against a library of personal statements previously submitted to UCAS, and a library of sample statements collected from websites and other sources.

UCAS-S5-Q2 — human review threshold, not safe allowance

Any statements showing a level of similarity of greater than 30% are reviewed by members of the UCAS Verification Team.

UCAS-S5-Q3 — institutional decision

The chosen universities and colleges decide on the significance of the results and what action, if any, to take.

UCAS-S5-Q4 — under Can I appeal against a similarity report?

The report highlights similarities to other data already available to us, and we do not expect any grounds for an appeal against this.
