ISI Kolkata overview: Quick snapshot

If you want one page of facts before you apply, this is it. The table below pulls together the core numbers you will quote in applications or interviews.

This snapshot helps you compare ISI with other research institutes. ISI focuses on statistics, mathematics, mathematical economics, information science and theoretical computer science.

Why choose ISI Kolkata: strengths and career outcomes

ISI’s reputation is built on research and rigorous maths training. Because of that, employers hire ISI graduates for research roles, analytics, quant finance and advanced studies.

Placements at ISI are strong for PG programmes. The reported placement percentage for recent PG batches is 100% , and the PG (2-year) median salary for 2023–24 was Rs. 21,77,000 . These figures come from the institute’s recent batch reports and placement summaries.

Top companies where ISI alumni work include big multinational banks and tech firms. LinkedIn counts show alumni at TCS (247) , HSBC (154) , JPMorgan Chase (112) and EY (81) . About 80% of alumni are in India and 20% abroad; 33% of alumni are in West Bengal.

ISI Kolkata overview: Programs offered — UG, PG, diplomas and research

ISI runs three main kinds of undergraduate programmes and a range of postgraduate, diploma and research programmes.

Fee note: B.Stat and B.Math generally do not levy tuition for most students. B.SDS tuition is Rs. 1,00,000 per semester (other academic fees Rs. 2,500 per semester ). Postgraduate diploma tuition is Rs. 25,000 per semester plus other fees Rs. 25,000 .

Student composition and intake figures

Know the classroom you will join. These are recent headcounts by level and gender.

Overall totals match the institute figure: 1,108 students. Gender balance is heavily male at present: 941 male and 167 female .

Seat matrix highlights for 2026–27 are: B.SDS total 75 seats (Kolkata 25 , Delhi 25 , Bengaluru 25 ). For B.Stat and B.Math the standard test-channel allotment (used in selection tables) lists 63 seats (main channel) plus other allocations and an INMO channel of 5 supernumerary seats for each of B.Stat and B.Math.

How admissions work: channels, eligibility and cutoffs

Three admission routes matter for you: the ISI Test channel, the INMO channel (for B.Stat/B.Math awardees), and JEE Main/CUET scores used for B.SDS.

Primary channels

• ISI Test channel — the default for many programmes. Admissions here are based on written tests (often two parts for UG) and merit.
• INMO channel — reserved, supernumerary seats for National Mathematical Olympiad (INMO) awardees. INMO candidates usually face an interview and have special qualification rules.
• JEE Main or CUET (Math+English) — used for B.SDS admission; ISI uses merit from these exams rather than its own written test for B.SDS.

Eligibility basics (verify programme pages before applying)

• B.Stat / B.Math: 10+2 with Mathematics and English. Entry mainly via the ISI Test channel; INMO awardees have a parallel route.
• B.SDS: 10+2 with Mathematics and English; ≥75% for general category (65% for SC/ST/PwBD) in the qualifying year. Admission is via JEE Main OR CUET (Math + English) .
• INMO channel interview qualifying marks: 50% (for those called via INMO).

Merit cutoffs example for B.SDS (composite score thresholds used in 2026 cycle)

Selection pattern for B.Stat and B.Math (ISI Test channel)

• Test I: MCQ mathematics (max score 120 ) — initially filters candidates.
• Test II: Descriptive mathematics (max score 80 ) — for those above cutoff.
• Final merit list prepared from combined performance.

If you plan to apply through INMO, expect an interview; qualifying marks used in recent cycles required 50% to pass the interview stage.

Step-by-step application checklist for aspirants

Follow this checklist to avoid last-minute mistakes. Keep scanned copies ready.

Documents you must have ready

• Class 10 and Class 12 certificates and mark sheets.
• ID proof (Aadhaar/PAN/passport) as specified on the portal.
• Proof of category (SC/ST/OBC/PwBD/EWS) if applicable.
• Pass certificates for INMO awardees and JEE/CUET scorecards for B.SDS applicants.
• Recent passport-size photograph and signature scanned as per portal specs.

Academic checks per programme

• B.Stat / B.Math: must have Maths at 10+2 level and English. If you are an INMO awardee, you must produce INMO documentation.
• B.SDS: prepare to submit JEE Main or CUET scores. Ensure your 10+2 percentage meets the category cutoff (≥75% general).

Preparation steps that work

• Revise Class 11–12 mathematics thoroughly—algebra, calculus, probability, combinatorics and geometry.
• Solve past ISI papers — they are the best guide to the level and style of questions.
• For INMO applicants, practice Olympiad-style proofs; interview qualifying mark is 50% .
• If you aim for B.SDS, sit JEE Main or CUET and focus on Maths and English sections.

Important timeline advice

We do not have exact application opening or closing dates here. Monitor the official ISI portal and the institute’s admissions notifications closely. Note the ISI governance and bill discussions in late 2025 to early 2026 (Nov 19, 2025 – Jan 28, 2026 ) for context, but admission schedules are published separately by the institute each year.

Fees, waivers and financial support

Costs and waivers affect your decision a lot. ISI mixes no-tuition programmes, fee-paying programmes and generous stipends.

Fee summary (semester-wise where applicable)

Fee waiver rules

• Category-based waivers: SC / ST / PwBD receive 100% tuition waiver where applicable.
• Income-based waivers: family income < Rs. 1 lakh/year gets 100% waiver; income Rs. 1–5 lakh/year gets 66.67% waiver.

Stipends and fellowships

Note: Some stipends apply only to students who meet residency or scholarship criteria. Check the official fellowship rules on ISI’s website.

Placements: trends, median salaries and employer map

If placement numbers matter to you, ISI’s recent PG placement rounds show strong outcomes.

• Reported PG placement rate: 100% for recent batches.
• PG (2-year) median salary for 2023–24 : Rs. 21,77,000 .

Employer map and roles

ISI graduates join quantitative finance teams, analytics and data science groups, software and research labs. The LinkedIn alumni snapshot shows heavy hiring at large banks and IT firms: TCS (247 alumni) , HSBC (154) , JPMorgan Chase (112) , EY (81) .

Geography of alumni

About 80% of alumni work in India, 20% abroad. Within India, 33% are located in West Bengal, with smaller clusters in Karnataka and Tamil Nadu. Abroad, alumni presence includes the US (14%) , Canada and other regions.

Student life, campus and accommodation (what we know and gaps)

ISI’s main campus is compact at 30 acres , with a high faculty-to-student ratio (497 faculty for 1,108 students). That usually means closer contact with professors and more research opportunities.

What is clear

• Strong academic environment focused on theory and research-minded teaching.
• Stipends and contingency grants for many programmes.
• Multiple campuses for some UG programmes (Kolkata, Delhi, Bengaluru).

What is not fully public (gaps you should check)

• Exact hostel and mess fee breakdown per semester is not in the public snapshot we used.
• Semester-wise subject lists and lab facility details for each programme require programme handbooks.
• Full faculty profiles and lab/research group descriptions are best checked on the institute’s official pages before you decide.

Where to find updated accommodation, fees and faculty details: the official ISI admissions pages and the specific programme brochure are the authoritative documents.
