Scope & Date:
This list is a pure meta-ranking that combines five major global university rankings. It uses the latest editions available on August 10, 2025:

• QS World University Rankings 2026
• ShanghaiRanking (ARWU) — Academic Ranking of World Universities
• Times Higher Education (THE) — World University Rankings
• Center for World University Rankings (CWUR)
• U.S. News & World Report — Best Global Universities

Important: No additional variables or bespoke indicators are introduced. We do not reuse the factors these providers use internally; we only take their final published ranks and combine them.

How the 5-in-1 score is computed

1. Collect ranks for each university from the five sources listed above (when available).
2. Normalize per source to a common 0–100 scale using percentile ranks (so lists with different sizes are comparable).
3. Trim extremes to reduce volatility: when a university has ≥3 source values, we remove one most favorable and one least favorable normalized value (robust outlier trimming).
4. Average the remainder to obtain a single unified score.
5. Rescale that score to the Top1000 index from 999 (best) to 0 (lowest) for display consistency across our catalog.
6. Missing data: If a university appears in fewer than 3 sources, we average the available normalized values without trimming (clearly marked internally during processing).

Why aggregate? Statistical advantages

• Noise reduction: Averaging independent lists dampens idiosyncratic measurement noise from any one provider.
• Bias mitigation: Provider-specific methodological biases (e.g., weight on research vs. teaching) tend to cancel out in the mean.
• Stability over time: Trimming extremes curbs rank whiplash caused by small methodology tweaks in a single source.
• Comparability: Percentile normalization aligns differently sized lists, making combined scores fairer.
• Coverage: Using multiple sources expands the pool of institutions that can be compared on a single, transparent scale.
