📚 QS Rankings: Why Indicator Weights Are Reviewed Every Year | QS排名：为什么指标权重每年都要重新审议
Every June, one publication reshapes the conversation in international admissions offices. The QS World University Rankings award a score between 0 and 100 to roughly 1,500 universities, and that score is assembled from a set of weighted indicators. What many A-Level and IB students never notice is that the weights themselves are not fixed: QS reconsiders them every year. This article explains how the weighting system works, why it is revised annually, and how to read a rank that may have been built on a different formula from last year's.
每年六月，一份榜单都会重新改写国际招生圈的讨论焦点。QS世界大学排名为约1500所大学打出0到100之间的分数，而这个分数由一组带权重的指标汇总而成。许多A-Level和IB学生没有注意到的是：权重本身并不是固定不变的，QS每年都会重新审议。本文将解释这套权重体系如何运作、为什么逐年修订，以及当今年的公式可能与去年不同时，你该如何解读一个名次。
1. What the QS Rankings Actually Measure | QS排名究竟衡量了什么
QS World University Rankings is produced annually by Quacquarelli Symonds, a UK-based higher education analyst. The global table has been published in its current form since 2004; before 2010 it was compiled jointly with Times Higher Education, which now publishes a rival table.
QS世界大学排名由总部位于英国的高等教育分析机构Quacquarelli Symonds每年发布。现行形式的全球榜单自2004年起发布；2010年之前，它由QS与《泰晤士高等教育》(THE)联合编制，如今THE则发布自己独立的榜单。
The final rank order is not a direct measurement of teaching quality. It is a composite score: each university receives a score between 0 and 100 on several indicators, and those indicator scores are multiplied by fixed weights and added together.
最终名次并不是对教学质量的直接测量，而是一个综合得分：每所大学在若干指标上获得0到100分，这些指标分数乘以固定权重后相加。
Because the weights are chosen by QS rather than derived
