It was declared an Institute of National Importance by an Act of Parliament in 1959 and functions under the Ministry of Statistics and Programme Implementation (MOSPI), Government of India.

ISI is globally recognised for its contributions to Statistics, Mathematics, Data Science, Computer Science, and Quantitative Economics. Many of India’s finest statisticians, data scientists, economists, and researchers are ISI alumni. An ISI degree opens doors to top research institutions worldwide, premier analytics firms, IITs, IIMs, and central government roles.

7. Exam Pattern

The ISI Admission Test is conducted in offline mode (pen and paper). The pattern differs for UG and PG programmes.

7.1 UG Programmes – B.Stat & B.Math

7.2 PG Programmes – M.Stat / M.Math

7.3 M.Tech Programmes

Candidates can seek admission to M.Tech (CS) and M.Tech (CrS) via a valid GATE score (direct interview call) or by appearing in the ISI Admission Test. M.Tech (QROR) requires the ISI test only — GATE scores are not accepted here.

8. Detailed Syllabus

8.1 B.Stat & B.Math (UGA / UGB)

8.2 M.Stat

8.3 M.Math

9. Selection Process

The selection for most ISI programmes follows a three-stage process:

1. Stage I – UGA/Objective Paper: All candidates appear. Those who meet the category-wise cutoff are shortlisted for Stage II.
2. Stage II – UGB/Subjective Paper: Papers of shortlisted candidates are evaluated. Composite score is calculated (weightage: Paper I × 1 + Paper II × 3). Top candidates are called for interview.
3. Stage III – Interview: Conducted at ISI campuses. Assesses mathematical maturity, logical reasoning, and depth of understanding. Final merit list is prepared using written + interview scores.

For M.Tech (CS / CrS) via GATE: Candidates with valid GATE scores above the ISI threshold are called directly for an interview, bypassing the written test.

11. Stipends, Fellowships & Fee Structure

One of ISI’s most remarkable features is that most flagship programmes come with a government-funded monthly stipend, making quality education nearly free and financially attractive.

11.1 Fee Concessions

• Full tuition fee waiver for SC / ST / PwBD candidates
• Income-based fee remission up to 100% for economically weaker students
• Contingency grants up to ₹20,000/year for research scholars
• BSDS has a separate, paid fee structure (not covered under stipend scheme)

12. Preparation Strategy & Best Books

12.1 Strategy for B.Stat / B.Math (UG)

• The difficulty level of the UGA (objective) section is comparable to the Pre-Regional Mathematics Olympiad (PRMO) level — go beyond JEE textbooks.
• For the UGB (subjective) section, practice writing complete, step-by-step proofs. A clean logical argument is valued more than a partially correct answer.
• Solve ISI Previous Year Question Papers religiously — available free on the official website. This is the single most effective preparation resource.
• The book “TOMATO” (Test of Mathematics at the 10+2 Level), published by ISI itself, is considered the Bible for B.Stat/B.Math aspirants.
• Focus on understanding concepts deeply, not just formula memorisation.
• Ideally begin preparation 6–10 months before the exam.

12.2 Recommended Books

12.3 Monthly Study Plan (6 months before exam)

12.4 Special Admission Routes (INMO Channel)

Students who have qualified for the Indian National Mathematical Olympiad (INMO) may be exempted from the ISI written test for B.Stat / B.Math and called directly for the interview. Check the official brochure each year for the exact INMO eligibility conditions.
