📚 UK Visa IELTS Requirements: CEFR Levels and Component Score Table | 英国签证对雅思成绩的要求：CEFR 等级与单项分数对应表
If you are applying for a UK visa that carries an English language requirement, the real question is never simply "what IELTS score do I need?". The Home Office sets its requirement as a CEFR level - A1, A2, B1, B2 or C1 - and then approves specific Secure English Language Tests (SELTs) that are allowed to certify that level. This guide converts those CEFR levels into IELTS band scores, explains the per-component rules that most applicants overlook, and gives you a route-by-route reference table you can plan your preparation against.
如果你正在申请带有英语语言要求的英国签证，真正的问题从来不是简单的一句"我需要考到多少分雅思"。英国内政部是以 CEFR 等级（A1、A2、B1、B2 或 C1）来设定要求的，并指定哪些"安全英语语言测试"（SELT）有权证明该等级。本文将把这些 CEFR 等级换算成雅思分数，解释大多数申请人容易忽视的单项分数规则，并提供一份可以据此规划备考的"按签证路线"对照表。
1. Why the UK Visa System Uses CEFR | 为什么英国签证体系采用 CEFR
The Home Office does not publish a single national IELTS cut-off. Instead, each immigration route in the Immigration Rules (mainly Appendix English Language) names a CEFR level, and the applicant must prove that level through an approved test or an accepted exemption.
英国内政部并不会公布一个全国统一的雅思录取分数线。相反，《移民规则》（主要是 Appendix English Language 附录）中的每一条移民路线都会指明一个 CEFR 等级，申请人必须通过受认可的考试或符合条件的豁免来证明达到该等级。
CEFR stands for the Common European Framework of Reference for Languages, published by the Council of Europe. It describes what a learner "can do" at six levels, from A1 (beginner) to C2 (mastery), rather than giving a raw score.
CEFR 是"欧洲语言共同参考框架"的缩写，由欧洲委员会发布。它用六个等级（从 A1 入门到 C2 精通）描述学习者"能够做什么"，而不是给出一个原始分数。
This matters because the same IELTS band can satisfy one route and fail another. A candidate with IELTS 5.5 overall may be comfortably above the B1 threshold for a Skilled Worker visa but still below the B2 threshold a university needs for a degree-level Student visa.
这一点非常关键：同一个雅思分数可能满足某条路线，却无法满足另一条。一位总分 5.5 的考生可能远高于技术工人签证所需的 B1 门槛，但仍低于大学为学位课程学生签证所要求的 B2 门槛。
2. The CEFR Scale Explained: A1 to C2 | CEFR 等级详解：A1 至 C2
Each CEFR level describes a band of independent ability. A1 and A2 are basic user levels; B1 and B2 are independent user levels; C1 and C2 are proficient user levels.
每个 CEFR 等级都描述了一段独立的能力区间。A1 与 A2 属于基础使用者等级；B1 与 B2 属于独立使用者等级；C1 与 C2 属于熟练使用者等级。
UK visa routes almost never require C2. In practice you will meet A1, A2 and B1 (mostly family and settlement routes) and B1 or B2 (work and study routes), with C1 occasionally appearing for professional registration bodies rather than for the visa itself.
英国签证路线几乎从不要求 C2。实际中你会遇到的是 A1、A2 和 B1（主要是家庭与永居路线），以及 B1 或 B2（工作与学习路线）；C1 偶尔出现，但通常来自职业注册机构的要求，而非签证本身。
| CEFR | Level name | Can-do summary | IELTS equivalent |
| A1 | Beginner | Simple everyday phrases, basic introductions | IELTS Life Skills A1 (Speaking & Listening only) |
| A2 | Elementary | Routine transactions, simple descriptions | IELTS Life Skills A2 (Speaking & Listening only) |
| B1 | Intermediate | Copes with familiar work, study and travel situations | IELTS 4.0 - 5.0 |
