美国加拿大本科 标化 文书 录取 时间线
美加两边都用四年制本科、都看高中成绩，真正的差别在录取时谁掌握决定权。美国的私立大学把申请拆成成绩、标化、文书、活动、推荐信几块，由招生委员会整体讨论；加拿大大部分专业先看课程和分数，达到线以后再处理补充材料。同一位学生用同一份成绩单投两边，结果经常完全不同，原因就在这里。
Both systems run four-year bachelor degrees and both ask for high school transcripts, yet the decision makers differ. Most US private universities review an application as a whole, weighing grades alongside test scores, essays and activities, while Canadian programmes usually start from course marks and prerequisite completion. The same transcript can produce very different outcomes depending on which side of the border it is sent to.
录取逻辑：整体评估与分数优先 / Whole-file review and mark-driven admission
美国顶尖私立大学的招生办会把每一份材料放进委员会讨论，成绩只是其中一个维度。高中选课难度、GPA 趋势、标化、文书、活动、推荐信会被放在一起比较，招生官还会看学生所在高中提供了多少门 AP 或 IB 课程。很多学生以为分数够高就稳了，实际上同一所高中里 GPA 相差 0.1 的两个人可能因为课程难度不同而排出相反的顺序。公立大学又是另一套逻辑，加州大学系统自 2021 年起不再把 SAT/ACT 放进录取公式，但把 A-G 课程完成情况看得更重。加拿大的大多数专业把高中最后两年的成绩和先修课放在最前面，安省申请者看六门 4U/M 课程，UBC 看 11 与 12 年级的课程组合，分数不够时文书基本没有翻盘空间。
Admission offices at selective US private universities read files in committee, and grades are one input among several. Course rigour, the trend across four years, test scores, essays, activities and references are compared side by side, with counsellors often asked how many AP or IB courses a school actually offers. Marks dominate in Canada: Ontario applicants are assessed on six 4U/M courses and UBC looks at the Grade 11 and 12 combination, so a weak average rarely gets rescued by a strong essay.
标化考试：test-optional 退潮与 2026 现状 / Standardised tests after the test-optional years
美国大学在 2020 年前后大面积实行 test-optional，2024 年起风向反转。MIT 在 2022 年 3 月率先宣布恢复 SAT/ACT，2023 年秋季入学适用。耶鲁、达特茅斯、布朗在 2024 年 2 到 3 月相继宣布 2025 年秋季入学起要求提交成绩，哈佛同年 4 月跟进，斯坦福把时间点放在 2026 年秋季。加州大学走的是相反方向，2021 年起 test-blind，提交了也不看。加拿大这边本科录取基本不要求 SAT/ACT，国际生要补的是语言成绩。多伦多大学官网列出的多数专业要求雅思总分 6.5、单项不低于 6.0，UBC 的直录门槛同样是 6.5 且单项 6.0。常见的错误是把美国那套 1500 分的目标直接套到加拿大申请上，白花几个月时间。
The test-optional wave that began around 2020 has partly reversed. MIT announced in March 2022 that it would require SAT or ACT scores again from autumn 2023, and Yale, Dartmouth and Brown followed in early 2024 for autumn 2025 entry, with Harvard and Stanford setting later start dates. The University of California went the other way and has been test-blind since 2021. Canadian universities generally do not ask domestic applicants for SAT or ACT; international applicants instead prove English proficiency, with the University of Toronto and UBC both listing an IELTS 6.5 overall and no band below 6.0 for most direct-entry programmes. Spending months chasing a 1500 on the SAT is wasted effort if Canada is the target.
申请系统：Common App 与 OUAC 的材料清单 / Application platforms and document lists
美国用 Common App、Coalition 或学校自己的系统，Common App 一篇 650 词主文书配七个题目选一个，活动列表最多填十项，每项 150 字符。加拿大没有全国统一系统，安省走 OUAC，101 表给本省高中生，105 表给外省与国际生。BC 省主要用 EducationPlannerBC，UBC 自己还有一套申请界面。两边材料数量差别很大，美国一份申请可能要写三到五篇补充文书，加拿大很多专业只收成绩单、课程描述和语言成绩。很多学生按美国节奏准备，到了十二月才发现 OUAC 的课程信息还没填完。
The US side runs on the Common App, the Coalition platform or a university's own portal; the personal essay is capped at 650 words and the activities list holds ten entries at 150 characters each. Canada has no single national application: Ontario uses OUAC, with the 101 form for local high school students and the 105 form for out-of-province and international candidates, while British Columbia leans on EducationPlannerBC and UBC keeps its own portal. A US application may require three to five supplemental essays; a Canadian one often asks for transcripts, course descriptions and a language score, nothing more.
课程与分数：四年难度曲线与六门先修课 / Course rigour and six prerequisite courses
美国招生官看的是四年课程表有没有逐年加难，AP、IB、Honours 的选课数量与校内排名会被放在同一所高中的上下文里比较，学校不提供 AP 并不算学生的问题。加拿大把先修课写得很死，申请工程要有微积分与物理，申请商科要有函数。安省的六门 4U/M 必须包含专业要求的科目。UBC 官网明确写出要看 11 与 12 年级的课程，个别专业还会要求具体分数。常见的错误是十一年级松了一年，十二年级再补，加拿大这边往往已经算进平均分。
US readers check whether the transcript gets harder each year and compare AP, IB or honours load within the context of what the school offers, so a school without AP is not held against the applicant. Canadian requirements are far more literal: engineering expects calculus and physics, business expects functions, and the Ontario six must include the listed prerequisites, with one missing course ending the application. UBC states on its website that both Grade 11 and Grade 12 results are considered and some programmes set minimum marks for specific subjects, and a light Grade 11 year cannot be fixed later.
文书与补充申请：650 词主文书与专业问卷 / Personal essays and programme-specific supplements
美国的主文书讲一个具体场景里的自己，而不是成就清单。补充文书回答为什么选这所学校、为什么选这个专业，招生官想看到判断力和细节。加拿大的补充材料集中在少数专业。多伦多大学工程要填学生档案，罗特曼商学院有额外的写作题，麦马健康科学有 supplementary application，其余大量专业不看文书。很多学生把美国那篇 650 词主文书原样投给加拿大，结果对方根本不读。反过来，只准备加拿大材料的学生到了美国补充文书阶段，往往拿不出能说明动机的具体例子。
The US personal essay is about a moment rather than a summary of achievements, and supplements explain why this university and this subject; readers look for judgement and concrete detail. Canadian supplements exist only in selected programmes, such as the University of Toronto engineering student profile, the Rotman Commerce written questions and the McMaster health sciences supplementary application, while most other programmes ignore essays entirely. Reusing a 650-word US essay for a Canadian application usually means nobody reads it.
活动与推荐信：持续投入与课堂细节 / Sustained activities and classroom references
美国把活动列表当成一份证据，用来判断学生在课堂之外持续做了什么。十项活动里招生官更在意两三项坚持了三年以上的事，而不是凑数。推荐信要找真正教过自己的老师，信里能写出课堂上的具体表现才有用。加拿大对活动的权重低得多，除了商科、工程、健康科学这类带补充申请的专业，大部分录取决定在成绩单上就完成了。常见的错误是为了活动列表去参加一堆一周的志愿项目，写出来全是同一个句式，招生办每年都能看到这类材料。
US readers treat the activities list as evidence of sustained commitment, and two or three entries lasting three years carry more weight than ten one-off items. References matter when the teacher can describe actual classroom behaviour rather than praised character. Canada gives activities much less weight; outside business, engineering and health sciences, most decisions are effectively made from the transcript, and a list of week-long volunteering projects written in identical sentences is a familiar sight in any admission office.
时间线：11 月早申与 1 月 15 日 / November early rounds and the 15 January deadline
美国早申请集中在 11 月 1 日，MIT 的 EA、哈佛的 REA 都在这一天。常规申请多在 1 月 1 日前后，Common App 每年 8 月 1 日开放。加拿大安省 OUAC 的 equal consideration 截止日期通常在一月中旬，2026 年入学是 1 月 15 日。UBC 与多伦多大学官网列出的冬季入学截止日期同样是 1 月 15 日。加拿大没有早申请，滚动审理的专业会按提交顺序发 offer，早交材料的优势比美国更明显。很多学生以为加拿大截止晚，实际上从十月开始就要处理课程描述与语言送分。
US early rounds cluster around 1 November, covering MIT's Early Action and Harvard's Restrictive Early Action, with regular deadlines near 1 January and the Common App opening on 1 August. Ontario's OUAC equal-consideration date falls in mid-January, 15 January for 2026 entry, and UBC and the University of Toronto list the same date for winter admission on their websites. Canada has no early round, but rolling programmes issue offers as files are completed, so submitting in October genuinely helps.
面试与第三方材料：校友面试与视频题 / Alumni interviews and video questions
美国不少大学提供校友面试，由当地校友志愿完成，形式偏交流，时间通常在提交申请后的十一月到一月。很多学生以为没收到面试邀请就是没戏，实际上名额按校友覆盖情况分配，没有面试并不会直接扣分。部分学校接受 InitialView 或 Vericant 这类第三方面试，国际生可以用它补充口语证据。加拿大的本科几乎不设面试，商科与健康科学把评估放进补充申请，用视频题或限时写作代替面对面交流。常见的错误是把面试当成口语考试，背一段自我介绍，校友想听的其实是学生为什么对这个专业感兴趣、最近读了什么。
Many US universities offer alumni interviews conducted by local volunteers between November and January, and the tone is conversational rather than adversarial; an invitation depends on alumni coverage in a region, so silence does not count against an applicant, a point that surprises families who expect a formal shortlist. A few schools accept third-party interviews such as InitialView or Vericant, which give international applicants another way to show spoken English, while Canadian universities rarely interview at all and business or health sciences programmes use video questions or timed writing inside the supplement instead. Rehearsing a memorised self-introduction misses the point, since interviewers ask why this subject and what the student has read recently.
费用与选校取舍：学费页面比排名表可靠 / Tuition pages and programme fit
美国私立大学四年的总花费通常高于加拿大国际生，加拿大各省之间也有差距，具体数字每年调整，看学校官网的 tuition 页面比看中介表格可靠。选校时更实际的分法是看专业。学费之外，生活费与汇率也要一起算进去。想读工程、计算机、商科，两边的课程结构差别会影响实习与就业。想读人文社科，美国的文理学院提供更小的课堂，加拿大则更依赖大课与讨论课。常见的错误是只按排名列表投十所，忽略了先修课与截止日期是否对得上。很多学生以为加拿大是美国的备选，实际上两边准备材料的顺序完全不同，十月之前就要决定主攻哪一边。
Private US universities generally cost more over four years than Canadian universities charge international students, and Canadian provinces differ from one another, so the tuition page on each university website is a better source than a summary table. Programme structure matters more than a ranking: engineering, computing and business differ in internship timing and accreditation, while liberal arts colleges in the US offer smaller classes than the large lecture halls common in Canada. Treating Canada as a backup usually fails, because the paperwork runs on a different calendar and the decision has to be made before October.
