List of Universities in the World (QS World University Ranking 2025 Recoded)

The QS World University Rankings categorize institutions based on several dimensions: size, academic focus, research intensity, and overall performance.

University size is classified into four categories: Extra Large (XL), Large (L), Medium (M), and Small (S).

Academic focus is categorized as follows: Specialist Universities (offering 1–2 faculties), Focused Universities (3–4 faculty areas), and Comprehensive Universities (covering all five major disciplinary areas).

Research intensity is assessed using four levels: Very High, (VH) High (HI), Moderate (MO), and Low (LO).

In addition to these attributes, QS assigns each institution nine performance metrics: academic reputation, employer reputation, student-to-faculty ratio, faculty research citations, proportion of international faculty, proportion of international students, degree of international research collaboration, graduate employment outcomes, and commitment to sustainability. These metrics contribute to a university’s overall ranking.

Without recoding the data, this may not be useful for research, especially for arithmetic and comparative operations.

QS世界大学排名（QS World University Rankings）从办学规模、学术定位、研究强度及综合表现多个维度对高等院校进行分类。
大学办学规模分为四大类别：超大型（Extra Large，XL）、大型（Large，L）、中型（Medium，M）与小型（Small，S）。
学术定位的分类标准如下：单科型大学（Specialist Universities，仅开设1-2个学院）、侧重型大学（Focused Universities，开设3-4个学科领域）与综合型大学（Comprehensive Universities，覆盖全部五大主流学科门类）。
研究强度采用四个等级开展评估：极高（Very High，VH）、高（High，HI）、中等（Moderate，MO）与低（Low，LO）。
除上述属性外，QS还为每所高校设置九项绩效评价指标：学术声誉、雇主声誉、师生比、教师研究引用量、国际教师占比、国际学生占比、国际研究合作程度、毕业生就业成果与可持续发展投入。上述指标共同影响高校的综合排名。
若未对该数据集进行重新编码，其将难以适配各类研究工作，尤其无法支撑算术运算与比较分析类研究。
