How is Indian Statistical Institute Kolkata ranked in 2026?

As of 2026, Indian Statistical Institute Kolkata's most recent national placement is the 101-150 rank band in the NIRF 2025 Overall category, while its strongest current standing is Rank #16 in the QS India University Rankings 2025 with a score of 67.00. The NIRF position marks a notable slide from Rank #75 in the NIRF 2024 Overall rankings, a fall of 26 places into the rank band.

In short, the institute remains a top-20 name in the QS India table even as its broad NIRF Overall position has weakened.

This page lays out exactly where Indian Statistical Institute Kolkata stands across the NIRF and QS frameworks, how those numbers have moved year on year, and what the trajectory means for an aspirant weighing this 1931-founded Institution of National Importance against its peers.

Year-Wise Rankings

The table below consolidates Indian Statistical Institute Kolkata's verified rankings across the NIRF (national) and QS (India and global-subject) frameworks for 2024, 2025 and 2026. It answers the core question an applicant asks: which body ranked the institute, in which category, at what rank, and with what score. Read each row as a single data point tied to one specific year; the NIRF Overall figures are national positions, the QS India figures are out of 100, and the QS 2026 entries are global subject-area bands rather than single ranks.

The takeaway is a split picture. On the national NIRF Overall measure, Indian Statistical Institute Kolkata moved the wrong way, dropping from Rank #75 in 2024 into the 101-150 band in 2025. On the QS India side, it edged up from Rank #17 in 2024 to Rank #16 in 2025, with its score improving from 66.10 to 67.00. For an applicant, this means the institute's international and subject-level reputation has held firm even as its all-rounder NIRF score has softened.

Ranking Trajectory of Indian Statistical Institute Kolkata

Indian Statistical Institute Kolkata's ranking trajectory points in two directions at once: improving in QS India but declining in NIRF Overall. The clearest movement is the NIRF Overall slide from Rank #75 in 2024 to the 101-150 band in 2025, a drop of 26 positions that pushed it out of the top-100 entirely and signals a genuine weakening in the broad-based NIRF assessment, which weighs teaching, research, graduation outcomes, outreach and perception together.

The QS India trend runs the other way. The institute climbed one place from Rank #17 (score 66.10) in 2024 to Rank #16 (score 67.00) in 2025, a small but positive move that keeps Indian Statistical Institute Kolkata firmly inside India's top 20 on QS's methodology. In the QS World University Rankings 2026 subject tables, it is placed in the 351-400 band for Economics and Econometrics and the 101-150 band for Social Sciences and Management, reflecting its long-standing research depth in statistics, mathematical economics and quantitative social science.

What does this divergence signal? NIRF rewards a wide spread of institutional metrics across all disciplines, so a highly specialised research institute like Indian Statistical Institute Kolkata can score lower there even while its core academic reputation stays strong, which is what the steadier QS India and QS subject results capture. An aspirant should read the NIRF dip as a caution flag on the institute's all-round NIRF standing, not as a verdict on the academic strength of its flagship statistics, mathematics and economics programmes.

How Indian Statistical Institute Kolkata Compares

Against its peers, Indian Statistical Institute Kolkata's positioning depends entirely on which framework you use. The verifiable headline is that it ranks #16 in the QS India University Rankings 2025 (score 67.00), placing it inside India's top 20 institutions on that table, ahead of many conventional universities but below the leading IITs and the Indian Institute of Science that typically occupy QS India's top tier. On the NIRF Overall 2025 measure, however, its 101-150 band placement sits well below the top technical and research institutes, which is a steep change from its Rank #75 standing in 2024.

The most meaningful comparison for a prospective student is by discipline rather than overall tables. In the QS World University Rankings 2026, Indian Statistical Institute Kolkata appears in the 351-400 band for Economics and Econometrics and the 101-150 band for Social Sciences and Management globally, areas where it competes with specialised economics and quantitative-science departments worldwide rather than with broad multi-faculty universities. For an applicant choosing among statistics, mathematics or economics-focused institutions, Indian Statistical Institute Kolkata's subject reputation and its top-20 QS India position are the more relevant benchmarks than the recently softened NIRF Overall band.
