AD Scientific Index's subject-based institutional rankings cover 24.405 institutions across 13 main fields. Universities may excel or fall behind in specific subjects, independent of their overall ranking. AD Scientific Index provides a comparative global performance assessment of universities in each field, making it a valuable indicator for equivalency or transfer applications. This ranking, currently in its Beta phase, is based on the Total H Index. Two new categories, 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 phase. The global, regional, national, and institutional subject rankings are still evolving as the 'Others' category (873.899 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.
