Tier Profile
How is Indian Institute of Science ranked?
Where does Indian Institute of Science rank?
BrightKey does not publish a single overall ranking number. We rate every university independently across six dimensions rather than collapsing it into one misleading position. On that basis, Indian Institute of Science sits in the global first tier — with 2 dimensions rated S-tier and 3 rated A-tier. Commercial rankings (QS, THE) swing yearly on methodology changes and draw roughly half their weight from reputation surveys; we think a dimension-by-dimension view is more reliable for the decisions families actually make.
Why doesn't BrightKey give Indian Institute of Science a QS-style rank?
Because a single rank blends six very different things — alumni network, employability, teaching quality, curriculum relevance, institutional health, and student experience — into one number that hides the trade-offs that matter most. A university that is S-tier on employability but B-tier on student experience means very different things for different students. We publish the rating on each dimension so you can judge by your own priorities.

📊 Graduate Outcomes
⚪ Outcome data not publicly available for this institution.
Why some data is missing →BrightKey's Assessment
Founded in 1909 by Jamsetji Tata and Maharaja Krishnaraja Wadiyar IV of Mysore, the Indian Institute of Science (IISc) is India's oldest and most prestigious research-led institution — a deemed university and 2018 Institution of Eminence, not an IIT. Of ~5,286 students, roughly 2,743 are doctoral and 2,010 postgraduate; undergraduates number only ~533, reflecting an institute built around research rather than teaching scale. IISc holds NIRF 2024 #1 in both the 'Research' and 'Universities' categories and #2 Overall (#2 again in 2025), and ranks ~#219 in QS World 2026 — where its standout is research intensity, consistently scoring near-perfect on citations-per-faculty, India's highest research output per academic. Its small undergraduate footprint is recent: the four-year Bachelor of Science (Research) launched its first batch in 2011, joined later by a B.Tech in Mathematics & Computing. The historic ~400-acre green Bengaluru campus (plus a 1,500-acre Challakere campus) hosts 40+ departments and India's first petascale supercomputer. Recent context includes a record ₹425-crore private donation (2022) to build a postgraduate medical school and a ₹1,470-crore 2024-25 budget under director Govindan Rangarajan.
Why These Ratings?
Tap any dimension below to see the evidence behind the tier.
Network StrengthA — Excellent
A — IISc's alumni and faculty network is elite but specialized: it dominates Indian academia, CSIR/DRDO/ISRO labs, and global research faculties (its PhDs populate top universities worldwide). It lacks the sprawling industry-and-startup alumni mass of the IITs, so the network is deep in science and R&D rather than broad across business and tech leadership.
EmployabilityA — Excellent
A — Outcomes are strong but narrow: graduates flow into PhD programs, faculty posts, ISRO/DRDO/CSIR, and deep-tech R&D, plus selective high-end recruiters. It is not an IIT-style mass corporate placement engine; UG and research cohorts are small and academia/R&D-oriented, so 'employability' in the conventional campus-recruitment sense is good but specialized rather than universal.
Teaching QualityA — Excellent
A — Faculty are world-class researchers and the student-to-faculty ratio is exceptional (~482 faculty for ~5,286 students). But teaching prestige derives from research stature, and the undergraduate teaching mission is young (first UG batch only in 2011) and small, so classroom-teaching maturity lags the institute's research eminence.
Curriculum RelevanceS — Exceptional
S — This is IISc's genuine top-5-globally dimension. By the systematic, publication-based metric of citations-per-faculty, IISc is India's #1 research institution and scores near-perfect on QS's citations indicator, with the country's highest research output per academic. Its curriculum is research-frontier across engineering, the sciences, and interdisciplinary centres, anchored by NIRF #1 'Research' standing.
Institutional HealthS — Exceptional
S — Outstanding. Institution of Eminence status, NIRF #1 Research / #2 Overall, a ₹1,470-crore budget, a record ₹425-crore private gift, and 115+ years of stable Tata-founded heritage make IISc one of the most financially and reputationally secure institutions in the developing world.
Student ExperienceB — Strong
B — Honestly weak by conventional undergraduate standards. The culture is research-monastic and postgraduate-dominated; with only ~533 undergraduates among nearly 5,300 mostly doctoral/PG students, social life, clubs, and the vibrant campus buzz of a large university are limited. The historic green campus is beautiful and calm, but the experience suits self-directed researchers, not students seeking a lively undergraduate community.
Strengths & Weaknesses
Strengths
- India's #1 research institution by citations-per-faculty — a systematic, publication-based metric where it approaches a perfect QS score
- NIRF 2024 #1 in both 'Research' and 'Universities' categories and #2 Overall (repeated #2 in 2025)
- Exceptional ~482-faculty-to-5,286-student ratio enabling intense research mentorship

Cost Estimate
For international students. Rates vary by program — these are typical ranges.
Tuition | UG (BS Research) ~₹25,000-35,000/year (~USD 300-450); PhD/research students typically pay nominal fees and receive monthly stipends (effectively net-positive) |
Living Costs | Hostel and living ~₹60,000-1,20,000/year (~USD 750-1,450), subsidized on-campus |
Total Annual | ~₹85,000-1,55,000/year all-in for UG (~USD 1,000-1,900); doctoral students are funded via stipends |
Admission Tips
Undergraduate (BS Research / B.Tech) admission runs through national exams — primarily JEE (Main/Advanced) and NEET, plus the IISER/IAT route; the legacy KVPY channel that historically fed IISc was discontinued and merged into national scholarship schemes around 2022, so target the current JEE/NEET pathways. Postgraduate and PhD entry runs through GATE and CSIR-UGC NET with interviews. Above all, IISc selects for research aptitude and demonstrated scientific curiosity, not breadth — applicants should signal genuine research intent, because the institute is research-first and selective by design.
Campus & City Life
IISc occupies a historic, leafy ~400-acre campus in north Bengaluru (with a second 1,500-acre Challakere campus), prized for its calm, green, academic atmosphere. The culture is research-monastic and postgraduate-dominated — with only ~533 undergraduates among nearly 5,300 mostly doctoral and PG students, the social scene is quiet and intellectually focused rather than a lively undergraduate hub. Excellent for students who want immersive research and serious peers; limited for those seeking a bustling, club-rich campus social life.
