📚 What is the International Baccalaureate (IB)? | 什么是国际文凭课程（IB）？
The International Baccalaureate (IB) is a globally recognised educational framework that develops inquiring, knowledgeable and caring young people. Founded in 1968 in Geneva, Switzerland, the IB offers four high-quality international education programmes to students aged 3 to 19. Unlike many national curricula, the IB focuses on holistic development, critical thinking and intercultural understanding. It now operates in over 5,000 schools across more than 150 countries. The most well-known of its programmes is the Diploma Programme (DP) for students aged 16 to 19, widely accepted by universities worldwide.
国际文凭课程（IB）是一个全球认可的教育框架，旨在培养具有探究精神、知识渊博且富有爱心的年轻人。IB 于 1968 年在瑞士日内瓦创立，为 3 至 19 岁的学生提供四种高质量的国际教育项目。与许多国家课程不同，IB 注重全人发展、批判性思维和跨文化理解。目前，IB 已在 150 多个国家的 5000 多所学校开展。其中最为人熟知的是面向 16 至 19 岁学生的文凭项目（DP），被世界各地的大学广泛认可。
1. What is the IB? | 什么是IB？
The IB is not a single exam board but a mission-driven educational foundation. It aims to create a better and more peaceful world through education. Rather than merely preparing students for tests, the IB encourages them to ask challenging questions, learn how to learn, and develop a strong sense of their own identity and culture. Its programmes are designed to be internationally transferable, meaning students can move between IB schools across different countries without disruption.
IB 并非一个单一的考试局，而是一个以使命为驱动力的教育基金会。它旨在通过教育创造一个更美好、更和平的世界。IB 不仅为学生备考，更鼓励他们提出有挑战性的问题，学会如何学习，并培养强烈的自我认同和文化意识。其项目设计具有国际可转移性，意味着学生可以在不同国家的 IB 学校之间顺利转学。
The IB learner profile describes a broad range of human capacities and responsibilities. These include being inquirers, thinkers, communicators, risk-takers, knowledgeable, principled, open-minded, caring, balanced and reflective. This profile underpins all four IB programmes and unites schools worldwide in a common educational philosophy.
IB 学习者画像描述了广泛的人类能力和责任，包括探究者、思考者、交流者、敢于冒险者、知识渊博者、有原则者、胸襟开阔者、富有爱心者、均衡发展者和反思者。这一画像贯穿所有四个 IB 项目，将全球学校凝聚在共同的教育理念下。
2. The IB Mission and Learner Profile | IB使命与学习者培养目标
The IB’s mission statement expresses its commitment to developing inquiring, knowledgeable and caring young people who help to create a better world through intercultural understanding and respect. The IB actively encourages students to become active, compassionate and lifelong learners. This mission is brought to life through the IB learner profile, a set of ten attributes that IB students strive to embody.
IB 的使命宣言表达了其致力于培养具有探究精神、知识渊博且富有爱心的年轻人，通过跨文化理解和尊重来创造更美好的世界。IB 积极鼓励学生成为积极主动、富有同情心的终身学习者。这一使命通过 IB 学习者画像得以实现，这是 IB 学生努力体现的十项特质。
For example, being an ‘inquirer’ means nurturing curiosity and developing skills for research. Being ‘principled’ involves acting with integrity and honesty, with a strong sense of fairness and justice. These attributes are not just academic aims but are embedded in classroom practice and school culture. Teachers design units that explicitly reference these traits, helping students to internalise them over time.
例如，“探究者”意味着培养好奇心，发展研究技能。“有原则者”涉及诚信行事、秉持强烈的公平和正义感。这些特质不仅是学术目标，还融入了课堂实践和学校文化。教师在教学设计中明确引用这些特质，帮助学生逐渐内化。
3. The Four IB Programmes | 四个IB项目
The IB offers a continuum of four programmes tailored to different age groups. The Primary Years Programme (PYP) is designed for children aged 3 to 12, nurturing their all-round development in the classroom and in the world outside. It focuses on inquiry-based learning through six transdisciplinary themes. The Middle Years Programme (MYP) spans ages 11 to 16, providing a challenging framework that encourages students to make practical connections between their studies and the real world. It comprises eight subject groups and culminates in a personal project.
IB 提供针对不同年龄段的四个连续项目。小学项目（PYP）面向 3 至 12 岁儿童，在课堂内外培养他们的全面发展。它以探究式学习为中心，围绕六大跨学科主题展开。中学项目（MYP）覆盖 11 至 16 岁，提供一个具有挑战性的框架，鼓励学生将学习与现实世界联系起来。它包括八个学科组，并以个人项目作为总结。
The Diploma Programme (DP) caters to students aged 16 to 19 and is an academically challenging and balanced programme with final examinations that prepares students for success at university and beyond. The Career-related Programme (CP), also for ages 16 to 19, integrates the academic rigour of the DP with career-related studies. It is ideal for students who wish to follow a vocational pathway alongside academic learning.
文凭项目（DP）面向 16 至 19 岁学生，是一个学术严谨且均衡的项目，以最终考试为评估方式，为学生大学及以后的成功做好准备。职业相关项目（CP）同样面向 16 至 19 岁，将 DP 的学术严谨性与职业相关学习相结合，适合希望在学术学习之外走职业路线的学生。
4. The Diploma Programme (DP) at a Glance | 文凭项目概览
The DP is the most widely offered IB programme and is often regarded as a gold standard in pre-university education. Students study six subjects concurrently, one from each of five groups, plus an arts subject or a second subject from another group. In addition to these academic courses, all DP students complete the three core components: Theory of Knowledge (TOK), the Extended Essay (EE), and Creativity, Activity, Service (CAS). The programme spans two years and is assessed through both internal and external examinations.
DP 是开设最广泛的 IB 项目，常被视为大学预科教育的黄金标准。学生同时学习六门科目，分别来自五个学科组，外加一门艺术科目或另一组的一门第二科目。除这些学术课程外，所有 DP 学生必须完成三个核心要素：知识论（TOK）、拓展论文（EE）和创造、行动与服务（CAS）。该项目为期两年，通过内部和外部考试进行评估。
DP grades range from 1 to 7 for each subject, with a maximum total of 42 points from the six subjects. Up to 3 additional points can be awarded for the combined performance in TOK and the EE, making the maximum possible score 45. Students must achieve at least 24 points to be awarded the diploma, provided they meet certain minimum requirements.
DP 每门科目的评分范围为 1 到 7，六门科目最高总计 42 分。TOK 和 EE 的综合表现最高可获得 3 分额外加分，因此满分是 45 分。学生必须至少获得 24 分，并满足特定的最低要求，才能获得文凭。
5. DP Curriculum: Six Subject Groups | DP课程：六大学科组
In the DP, students must choose one subject from each of the first five groups: Group 1 – Studies in Language and Literature; Group 2 – Language Acquisition; Group 3 – Individuals and Societies; Group 4 – Sciences; Group 5 – Mathematics. The sixth subject can be chosen from Group 6 – The Arts, or students may select an additional subject from Groups 1 to 4. This structure ensures breadth and balance, preventing premature specialisation.
在 DP 中，学生必须从前五个学科组中各选一门科目：第一组 – 语言与文学研究；第二组 – 语言习得；第三组 – 个人与社会；第四组 – 科学；第五组 – 数学。第六门科目可从第六组 – 艺术中选修，或者从第一至第四组中再选一门。这一结构保证了广度和均衡，避免了过早专业化。
Within each group, schools offer a range of options. For example, Group 3 includes subjects like History, Economics, Psychology and Geography. Group 4 includes Biology, Chemistry, Physics and Computer Science. Mathematics from Group 5 is offered at different levels: Analysis and Approaches, and Applications and Interpretation, each available at Standard Level (SL) or Higher Level (HL). Students typically take three subjects at HL and three at SL.
每个学科组内，学校提供一系列选项。例如，第三组包括历史、经济学、心理学和地理等。第四组包括生物学、化学、物理学和计算机科学。第五组的数学分为不同水平：分析与方法，以及应用与解释，各有标准水平（SL）和高级水平（HL）。学生通常选择三门 HL 和三门 SL 科目。
6. The Core: TOK, EE, CAS | 核心：知识论，拓展论文，创造、行动与服务
The DP core is what distinguishes the IB from many other qualifications. Theory of Knowledge (TOK) is a course about critical thinking and the nature of knowledge. Students explore how we know what we claim to know and reflect on knowledge questions from different areas of knowledge. The course is assessed through an exhibition and a 1,600-word essay. It adds an interdisciplinary dimension to the student’s studies.
DP 的核心是 IB 与其他许多资格的显著区别。知识论（TOK）是一门关于批判性思维和知识本质的课程。学生探索我们如何知道自己声称知道的东西，并反思来自不同知识领域的问题。该课程通过一个展览和一篇 1600 字的论文进行评估。它为学生的学习增添了跨学科维度。
The Extended Essay (EE) is an independent, self-directed piece of research, culminating in a 4,000-word paper. Students choose a topic of interest from one of their DP subjects and conduct in-depth investigation under the supervision of a teacher. This exercise develops the research, writing and analytical skills essential for university. Creativity, Activity, Service (CAS) requires students to engage in a range of experiences alongside their academic studies, involving creative thinking, physical exertion, and unpaid and voluntary service. CAS is not formally assessed but must be completed and documented.
拓展论文（EE）是一项独立的、自主导向的研究，最终形成一篇 4000 字的论文。学生从所学 DP 科目中选择感兴趣的题目，在教师指导下深入研究。这项练习培养学生大学所必备的研究、写作和分析能力。创造、行动与服务（CAS）要求学生参与一系列体验，涉及创意思维、身体力行的活动以及无偿志愿服务。CAS 不进行正式评分，但必须完成并有证据记录。
7. Assessment and Scoring in the DP | DP的评估与评分
DP assessment is criterion-based, meaning students are measured against defined standards rather than ranked against each other. Final exams take place in May or November and are marked by external examiners. Each subject includes internal assessments (IA) such as oral commentaries, portfolios, or lab reports, which are marked by teachers and moderated by the IB. The weighting between external exams and IA varies by subject.
DP 的评估基于标准，即根据既定标准衡量学生，而非相互排名。最终考试在五月或十一月举行，由外部考官评阅。每门学科包含内部评估（IA），如口头评论、作品集或实验报告，由教师评分并由 IB 进行外部审核。外部考试和 IA 的权重因学科而异。
The overall score is out of 45: up to 42 from the six subjects (each scored 1–7) and up to 3 from the combined TOK and EE grades, which are assessed on a matrix. A student must achieve at least 24 points, with at least 12 points from HL subjects, and complete CAS to receive the diploma. Grade boundaries ensure consistency across sessions and languages.
总分为 45 分：六门科目最高 42 分（每门 1-7 分），TOK 和 EE 通过矩阵评估最多可得 3 分。学生必须至少获得 24 分，且 HL 科目至少获得 12 分，并完成 CAS，才能获得文凭。等级分数线确保了不同考试时段和语言之间的一致性。
8. IB vs A-Levels: Key Differences | IB与A-Level的关键区别
While both the IB Diploma and A-Levels are well-respected pre-university qualifications, they differ significantly in structure and philosophy. A-Level students typically specialise in three or four subjects, allowing for deep focus, whereas the IB mandates breadth across six subjects. The IB also includes a compulsory core (TOK, EE, CAS) which has no equivalent in A-Levels. This means IB students continue to study a language, a science and mathematics alongside humanities, regardless of their intended university major.
虽然 IB 文凭和 A-Level 都是备受推崇的大学预科资格，但它们在结构和理念上有显著不同。A-Level 学生通常专攻三到四门科目，可以深入聚焦，而 IB 则要求六门科目的广度。IB 还包含必修的核心要素（TOK、EE、CAS），A-Level 中并无类似部分。这意味着 IB 学生在学习人文社科的同时，还要继续学习一门语言、一门科学和数学，无论他们计划在大学主修什么。
Assessment methods also vary: IB uses a mix of final examinations and coursework (IA) in all subjects, fostering research and project-management skills. A-Levels are predominantly examined through end-of-course papers, although some subjects have coursework. In terms of recognition, both are widely accepted, but the IB is often valued for its holistic approach and international outlook. The choice depends on a student’s learning style and academic goals.
评估方法也有所不同：IB 所有科目均采用期末考试与课程作业（IA）相结合的方式，培养研究和项目管理技能。A-Level 则主要通过课程结束时的考试进行评估，尽管部分科目包含课程作业。在认可度方面，两者均被广泛接受，但 IB 常因其全人教育和国际视野而受重视。选择哪种取决于学生的学习风格和学术目标。
9. University Recognition and Benefits | 大学认可与优势
The IB Diploma is accepted by universities in over 100 countries, including all UK universities, most US colleges, and institutions across Canada, Australia, Europe and Asia. Many universities publish specific IB offers and recognise the DP as excellent preparation for higher education. The IB’s emphasis on independent research, critical thinking and time management gives students a distinct advantage in university admissions and undergraduate studies.
IB 文凭被 100 多个国家的大学认可，包括所有英国大学、多数美国高校，以及加拿大、澳大利亚、欧洲和亚洲的院校。许多大学公布具体的 IB 录取要求，并认为 DP 是高等教育的绝佳准备。IB 对独立研究、批判性思维和时间管理的重视，使学生在大学申请和本科学习中具有明显优势。
In the UK, typical IB offers from top universities might range from 32 to 38 points with specific HL grades. For example, an offer from the University of Oxford for Economics might require 39 points with 7,6,6 in HL subjects. In the US, strong IB scores can lead to advanced standing or college credits. Furthermore, the CAS component demonstrates a student’s commitment to community service, a quality valued by many admissions officers.
在英国，顶尖大学的典型 IB 录取条件可能在 32 到 38 分之间，并对 HL 成绩有特定要求。例如，牛津大学经济学专业的录取可能要求总分 39 分，HL 科目 7,6,6。在美国，优异的 IB 成绩可换取先修课程学分或大学学分。此外，CAS 部分展现了学生对社区服务的投入，这一品质受到许多招生官的重视。
10. Is the IB Right for You? | IB适合你吗？
The IB Diploma is ideal for students who enjoy a broad education, are curious about connections between subjects, and wish to develop transferable skills like public speaking, research and collaborative problem-solving. It suits those who are self-motivated, well-organised, and prepared to balance academic rigour with personal development. However, the workload is significant, and time management is crucial. Students who prefer in-depth specialisation in a narrow field may find A-Levels more suitable.
IB 文凭适合那些喜欢广博教育、对学科之间的联系充满好奇，并希望培养公众演讲、研究和协作解决问题等可迁移技能的学生。它适合那些积极主动、条理清晰，并愿意在学术严谨与个人发展之间取得平衡的人。然而，课业量很大，时间管理至关重要。偏爱在狭窄领域深入钻研的学生可能会觉得 A-Level 更合适。
Before choosing the IB, it is wise to assess your own learning preferences. Speak with IB coordinators, current students, and teachers to understand the day-to-day demands. Remember that the IB learner profile is not just a goal for students but a lifelong ethos. If you value intercultural awareness and a holistic view of education, the IB can be a transformative experience that extends well beyond the classroom.
在选择 IB 之前，明智的做法是评估自己的学习偏好。与 IB 协调员、在读学生和老师交流，了解日常要求。请记住，IB 学习者画像不仅是学生的目标，更是一种终身精神。如果你重视跨文化意识和整体教育观，IB 可以成为超越课堂的、具有变革意义的体验。
