📚 What Is the QS Stars Rating System: No Comparisons, Only Your Own Performance | QS Stars 评级是什么：不与他人比较，只评自身表现
Choosing a university is rarely a simple question of "who is number one". Applicants weigh course structure, cost, location, graduate outcomes and accreditation, and they increasingly run into a badge called QS Stars on university websites. Yet very few students can explain what that badge actually measures, what it does not measure, or why its designers deliberately refuse to compare institutions with one another. This article unpacks the QS Stars rating system from the ground up: its philosophy, its categories, its scoring logic, its limitations, and the sensible way to use it in your own university research.
选校很少是简单的"谁排第一"的问题。申请者要权衡课程结构、费用、地理位置、毕业生去向和认证情况，而在此过程中，他们越来越多地在大学官网上遇到一个叫 QS Stars 的标识。然而真正能说清这个标识究竟衡量什么、不衡量什么、以及它的设计者为何刻意不把院校相互比较的学生，少之又少。本文将从头拆解 QS Stars 评级体系：它的理念、类别、评分逻辑、局限，以及在自己做择校调研时理性使用它的方法。
1. What Is QS Stars? | QS Stars 是什么
QS Stars is a voluntary rating and audit system operated by QS Quacquarelli Symonds, the same organisation behind the QS World University Rankings. Instead of producing a numbered league table, it awards an institution an overall rating from one star to five stars, plus a higher "5 Stars Plus" tier. The output is a badge accompanied by a detailed evaluation report, not a position in a list.
QS Stars 是由 QS Quacquarelli Symonds（即发布 QS 世界大学排名的同一机构）运营的自愿性评级与审计体系。它不产出带序号的排行榜，而是向院校颁发从 1 星到 5 星的整体评级，并另设更高的"5 Stars Plus"层级。最终产出是一枚标识加上一份详细评估报告，而不是榜单上的一个名次。
The system covers universities, colleges and business schools, and some variants extend to pathway providers and online education providers. An institution opts in, submits documentary evidence, and is assessed against a framework that is fixed in advance and covers areas such as teaching, employability, internationalisation, research and facilities. Because the framework is set before assessment begins, each institution faces the same yardstick rather than facing each other.
该体系覆盖大学、学院和商学院，部分版本还延伸至预科机构与在线教育机构。院校自愿申请、提交书面证据，然后按照一套事先确定的框架接受评估，框架涵盖教学、就业力、国际化、科研、设施等领域。由于框架在评估开始前就已确定，每所院校面对的是同一把尺子，而非彼此之间的相互较量。
Two features are worth noting from the outset. First, QS Stars is funded by the institutions that apply, which makes it a commercial service as well as an evaluation exercise. Second, the rating is time-limited: a badge is normally valid for a defined period, after which the institution must be re-evaluated if it wishes to keep displaying it. Always check the date on a badge before drawing conclusions from it.
有两点从一开始就值得注意。第一，QS Stars 由提出申请的院校付费，因此它既是评估活动，也是一项商业服务。第二，评级具有时效性：标识通常只在特定期限内有效，到期后院校若想继续展示，就必须重新接受评估。因此在依据一枚标识下结论之前，务必先看它的日期。
2. The Core Idea: An Audit, Not a League Table | 核心理念：自我审计，而非排行榜
The single most important distinction to grasp is the difference between a ranking and a rating. A ranking is relative and zero-sum: if one institution moves up, another must move down, because the ordering itself is the product. A rating is absolute and threshold-based: an institution either meets the criteria for a star or it does not, regardless of what anybody else achieves.
最需要把握的一点，是"排名"与"评级"之间的区别。排名是相对的、零和的：一所院校上升，必然有另一所下降，因为次序本身就是其产品。评级则是绝对的、基于门槛的：一所院校要么达到某星级的标准，要么没达到，与其他人取得什么成绩无关。
This is why QS frames the process as closer to an audit than a competition. The guiding question is not "are you better than your neighbour?" but "how do you perform against a defined standard, and where are your own strengths and weaknesses?" That reframing matters enormously for institutions whose mission is not to be a global research powerhouse, such as specialist arts colleges, teaching-intensive universities or regional institutions with strong local impact.
正因如此，QS 把这一过程定位为更接近审计，而非竞赛。其核心问题不是"你是否比隔壁那所更好"，而是"对照既定标准，你的表现如何？你自身的强项与短板在哪里？"对于使命并非成为全球科研强校的机构而言——例如专业艺术院校、以教学为主的大学，或具有强大区域影响力的地方院校——这种框架转换意义极其重大。
A practical consequence follows: many institutions can hold the same star rating simultaneously. Five stars is not a trophy owned by one university; it is a threshold that a substantial number of institutions can reach. Ties are the norm, not the exception, and this is a design choice rather than a flaw.
由此产生一个实际结果：许多院校可以同时拥有相同的星级。五星不是某一所大学独享的奖杯，而是大量院校都能跨过的一条门槛。并列是常态而非例外，而这属于设计选择，而非缺陷。
3. The Assessment Categories | 评估类别
The overall rating is assembled from a set of categories. Some are treated as core and must be assessed; others are optional and are selected by the institution to reflect its own profile and mission. The exact list has been revised over time, so treat the table below as a structural overview and always consult the current published methodology.
整体评级由一组类别汇总而成。其中一些属于核心类别，必须接受评估；另一些则是可选类别，由院校根据自身特点与使命自行选择。具体清单历经修订，因此请把下表视为结构概览，并务必查阅最新公布的方法说明。
| Category | 类别 | Status | 性质 | Typical focus | 典型关注点 |
| Teaching | 教学 | Core | 核心 | Student-faculty ratio, qualifications, satisfaction, completion | 师生比、师资资历、学生满意度、完成率 |
| Employability | 就业力 | Core | 核心 | Graduate outcomes, employer links, careers support | 毕业生去向、雇主合作、就业服务 |
| Internationalisation | 国际化 | Core | 核心 | International staff and students, partnerships, mobility | 国际师资与学生、合作项目、交流流动 |
| Research | 科研 | Core or optional | 核心或可选 | Output, citations, grants, doctoral provision | 产出、引用、科研经费、博士培养 |
| Facilities | 设施 | Core or optional | 核心或可选 | Libraries, laboratories, accommodation, campus services | 图书馆、实验室、住宿、校园服务 |
| Online Learning | 在线学习 | Optional | 可选 | Digital delivery quality, platform, learner support | 数字教学质量、平台、学习者支持 |
| Innovation | 创新 | Optional | 可选 | Enterprise, spin-outs, incubators, patents | 创业、衍生企业、孵化器、专利 |
| Arts & Culture | 艺术与文化 | Optional | 可选 | Creative provision, cultural partnerships, venues | 创意课程、文化合作、场馆资源 |
| Inclusiveness | 包容性 | Optional | 可选 | Access, scholarships, support for underrepresented groups | 入学机会、奖学金、对弱势群体的支持 |
| Specialist Criteria | 专业特色标准 | Optional | 可选 | Discipline-specific strengths, niche provision | 学科特定优势、特色课程 |
| Social & Environmental Impact | 社会与环境影响 | Optional | 可选 | Sustainability, community engagement, ethics | 可持续性、社区参与、伦理治理 |
The optional categories are the mechanism that makes "no comparison" workable in practice. A conservatoire can choose to be judged on arts and culture; a technology-focused university can emphasise innovation and employability; a provider serving working adults can opt into online learning. Each institution is therefore evaluated on the profile it actually claims to have, rather than on a single template imposed on everyone.
可选类别正是让"不比较"在现实中可行的机制。音乐学院可以选择按艺术与文化接受评判；以技术为核心的大学可以突出创新与就业力；服务在职成人的教育机构可以选择在线学习类别。于是每所院校都是按它自己声称拥有的定位被评估，而不是被套上同一个模板。
4. The Star Levels and What They Mean | 星级等级及其含义
QS Stars uses a scale running from one star to five stars, with an additional "5 Stars Plus" tier at the top. Broadly speaking, a higher star count indicates that the institution met thresholds across more of the criteria assessed, at a higher level of evidence. The table below summarises the conventional reading of each level.
QS Stars 采用从 1 星到 5 星的等级，并在顶端额外设置"5 Stars Plus"层级。大体而言，星级越高，意味着该校在所评估的更多标准上、以更高的证据水平达到了门槛。下表概括了各层级的通常含义。
| Rating | 评级 | Conventional reading | 通常解读 |
| 1 Star | 1 星 | Meets a basic minimum across the assessed areas | 在所评估领域达到基础最低标准 |
| 2 Stars | 2 星 | Developing provision with identifiable strengths | 办学处于发展中阶段，已有可识别的优势 |
| 3 Stars | 3 星 | Solid, well-rounded performance in most areas | 在多数领域表现稳健、均衡 |
| 4 Stars | 4 星 | Strong performance, often internationally oriented | 表现强劲，通常具有国际化取向 |
| 5 Stars | 5 星 | Excellent performance across the core categories | 在核心类别上表现卓越 |
| 5 Stars Plus | 5 星+ | Top-tier performance in core areas plus distinction in specialist criteria | 核心领域达到顶尖水平，并在专业特色标准上表现突出 |
An important nuance is that categories are often rated individually as well as in aggregate. An institution might hold an overall five-star rating while its research category sits at four stars, or hold a five-star teaching category within a four-star overall profile. This is exactly why the badge alone is a poor basis for a decision, and why the underlying category breakdown is where the real information lives.
一个重要的细节是：除了整体评级，各类别往往也会单独给出星级。一所院校可能整体为五星，但科研类别为四星；也可能整体为四星，却在教学类别上拿到五星。这正是单看标识不足以做判断的原因，也是真正有价值的信息藏在类别细分里的原因。
5. How the Scoring Actually Works | 评分机制如何运作
Within each category there are indicators, and each indicator carries a maximum number of points. An institution earns points based on the evidence it supplies, the points are summed to produce a category score, and the category score is compared against a threshold set by QS. Clear the threshold and the category earns its star; the overall rating then follows from the total achieved across the core categories. The precise point values and cut-offs are published in QS's methodology documentation and are revised periodically.
每个类别之下设有若干指标，每个指标带有最高分值。院校依据提交的证据获得分数，分数累加得出类别得分，类别得分再与 QS 设定的门槛比较。跨过门槛，该类别即获得对应星级；整体评级则由核心类别的总分推导而来。具体分值与临界值公布在 QS 的方法说明文件中，并会定期修订。
Category Score = Σ (Indicator Points) → compared with Category Threshold
Overall Rating = f (Total Core Category Score)
Because the scoring is absolute rather than normalised against a peer group, it is technically possible for every institution in a given year to be awarded five stars, and equally possible for none to be. There is no curve and no quota. This is the mathematical expression of the "no comparison" principle, and it is the clearest way to explain the system to someone who assumes all university badges are rankings in disguise.
由于评分是绝对的，而非在同类院校之间做归一化处理，理论上某一年的所有院校都可能获得五星，也完全可能一所都没有。这里没有正态分布曲线，也没有名额配额。这正是"不比较"原则在数学层面的体现，也是向那些以为所有大学标识都是"伪装的排名"的人解释该体系时最清晰的方式。
