Institutional Subject Ranking

World Bulgaria Institutional Subject Rankings 2025

AD Scientific Index's subject-based institutional rankings, covering 24.369 institutions across 13 main fields, serve as a crucial reference for evaluating cross-border transfer or graduation equivalency applications. Universities may excel or fall behind in specific subjects, apart from their overall ranking. AD Scientific Index provides a comparative global performance assessment of universities in each subject, making it a valuable indicator for equivalency or transfer applications. This ranking, based on the Total H Index, is in Beta. Two new additions, Art and Humanities University Rankings and Social Sciences and Humanities University Rankings, offer a unique focus exclusively on arts, humanities, and social sciences, excluding medicine, engineering, and natural sciences. Please note that both rankings are in their Beta version. The global, regional, national, and institutional subject rankings are still evolving as the 'Others' category (931.668 profiles) contains scientists whose fields are unidentified or yet to be edited, so rankings may change accordingly. Rankings reflect the presence of scientists in a branch, not whether the institution has a dedicated faculty. See also: Individual Subject Rankings.
