What the index measures
The published methodology begins with public Google Scholar researcher profiles and considers the H-index, i10-index and citations over both total-career and recent five-year windows. The institutional table is therefore rooted in researcher publication and citation performance; it is not a reputation survey or a comprehensive score of every university mission.
Staff denotes researcher profiles associated with an institution in the AD Scientific Index database, not the institution's official headcount. Top 10 counts profiles in the highest-performing 10% group for the selected view; it does not mean the first ten researchers. Definitions are available in the official indicator guide.
How to use the result
The table can support monitoring of publication and citation strength and the distribution of highly performing researchers. It does not directly assess teaching, student experience, graduate employment or the full social mission of a university, so it should be read alongside other evidence.
Near real-time does not mean that every new citation appears instantly, and the database does not automatically include every public Google Scholar profile. Readers should retain the 7 August 2026 observation date and revisit the official Thailand table before using the figures in a later publication.
