Admission rules & eligibility simplified
Getting into IIST is straightforward in terms of process — but the eligibility filters are strict.
Main eligibility rules: - Admission based solely on JEE Advanced score. - Class XII minimum marks: 75% for GEN/EWS/OBC-NCL; 65% for SC/ST. - JEE Advanced minimum category marks (2025): General 20% aggregate (with at least 5% in each PCM), EWS/OBC-NCL 18% , SC/ST/PD 10% .
What you need at counselling: - JEE Advanced scorecard and rank proof. - Class XII mark sheet/certificate showing the required percentage. - Photo ID, caste/EWS certificates if applicable, and documents for any reservation you claim. - Bank/payment details for fee submission.
After JEE Advanced results: register on IIST’s admission/counselling portal and follow the seat allotment rounds. There are limited seats; being ready with documents and funds speeds up acceptance.
Cutoff and rank guidance (2025 patterns you should note)
IIST cutoffs move by branch and category. Use the 2025 opening and closing numbers as reality checks for target ranks.
JEE Advanced percentage opening/closing (2025) for General category (selected branches):
| Branch | Open (%) | Close (%) |
|---|---|---|
| Aerospace Engineering | 43.06% | 28.61% |
| ECE (Avionics) | 40.56% | 28.33% |
| CSE (Data Science) | 42.78% | 30.28% |
| Dual Degree | 36.94% | 28.06% |
UG admission rank ranges — General category (2025)
| Branch | Opening Rank | Closing Rank |
|---|---|---|
| Aerospace Engineering | 92 | 1076 |
| ECE (Avionics) | 135 | 1091 |
| CSE (Data Science) | 93 | 822 |
| Dual Degree | 264 | 1174 |
What this means for your target: - If you want Aerospace (General), aim for a JEE Advanced rank substantially better than 1076 — target under 1000 to be safe. - For ECE (Avionics), target under about 1,000–1,100 (General category closing was 1091 in 2025). - CSE (Data Science) is competitive but had a closer closing rank ( 822 ) in 2025 — aim for under 800 . - Dual degree openings and closes were wider; still, aim to beat the closing rank ( 1174 ) comfortably.
Remember: category cutoffs differ. Use your category’s opening/closing ranks from the 2025 table as the best guide available.

Placements and salary reality check (2024–25 data you should know)
IIST placement numbers are solid but not uniform across programmes. Here are verified numbers from the NIRF 2026 dataset for the 2024–25 batch.
UG (4-year) placement snapshot (batch 2024–25):
| Category | 2024–25 |
|---|---|
| Intake | 134 |
| Admitted | 131 |
| Graduated | 119 |
| Placed | 80 |
| Higher studies | 21 |
| Placement % | 81.6% |
| Median salary | Rs. 11,98,296 |
Course-level numbers from placements 2024–25: - B.Tech highest package: Rs. 38.5 LPA . - B.Tech typical median shown elsewhere in placement reports: ~Rs. 11 LPA (useful when comparing branch-level medians). - M.Tech median: Rs. 11.5 LPA and highest ~ Rs. 15 LPA (as per placement summary).
Top recruiters include a mix of NewSpace startups and established tech companies: ISRO and other DoS centres, Skyroot Aerospace, Agnikul Cosmos, Tata Advanced, GE Vernova, Bosch, C-DAC, Texas Instruments and consulting firms among others.
What these numbers mean for you: - Median salary around Rs. 12 LPA is a strong outcome for a specialised space-focused institute. - The highest packages are skewed by a few offers outside the typical ISRO pipeline; average B.Tech placement outcomes vary by branch. - About 15–20% of a graduating batch typically go for higher studies rather than placements.
IIST → ISRO: eligibility, selection mechanics and realistic odds
IIST historically offers a direct pipeline to ISRO, but it's conditional now.
Hard eligibility filters for ISRO hiring through IIST: - Minimum CGPA: ≥ 7.5 on a 10-point scale. - No active backlogs at the time of recruitment. - Medical fitness as per ISRO standards.
Selection mechanics: - Shortlist students meeting the CGPA threshold and other eligibility. - Technical interviews focus on fundamentals, projects, and fit for specific centres and roles. - Not all eligible students get selected; across recent batches approximately 60–64% of students met the CGPA ≥7.5 threshold.
Historical absorption into ISRO: a total of 1,430 candidates joined ISRO through IIST till March 2025 . That’s a significant number, but not a guarantee for every batch member.
How to maximise your ISRO chances: - Keep a steady academic record to maintain CGPA ≥ 7.5 ; avoid backlogs. - Choose final-year projects with clear relevance to ISRO (satellite systems, control systems, sensors, software for embedded systems). - Intern early in ISRO labs or accredited DoS/industry labs if you can secure internships.
Scholarships, fee waivers and cost-reduction strategies
IIST runs merit-based scholarships. Two commonly cited schemes: - Top Rank Scholarship: Top 5 students (JEE Advanced AIR ≤ 1000) get 100% fee waiver for the first year . Condition: maintain CGPA ≥ 9.0 each year. - CGPA-Based Scholarship: Students achieving CGPA ≥ 9.0 in any semester may get 50% fee waiver for the next semester . This is limited to 10% of students per program .
Practical tips to reduce cost: - Target the Top-5 scholarship if you are within the JEE Advanced AIR ≤ 1000 range. - Work for CGPA-based waivers by planning assessments and avoiding early-year backlogs. - Apply for external grants (minor research fellowships) and conference travel support when working on projects. - Use the institute’s placement stipends or part-time research assistant roles to cover small recurring costs.
Prep plan: timeline, study targets and application checklist
Use the 2025 cutoffs and fee facts to build a clear pre- and post-JEE plan.
Short timeline and targets: - Before JEE Advanced: aim to solve at least 50 full-length Advanced-level papers in the last 6 months. Target ranks based on 2025 closings: - Aerospace (General): aim for ≤ 1000 (closing 1076). - ECE Avionics (General): aim for ≤ 1,000–1,100 (closing 1091). - CSE Data Science (General): aim for ≤ 800 (closing 822). - Dual degree: aim for ≤ 1,100 (closing 1174).
Admission-season checklist (what to have ready when counselling opens): | Task | Why it matters | |---|---| | JEE Advanced scorecard & printout | Required for verification | | Class XII mark sheet | Must meet 75% / 65% threshold | | Caste/EWS certificates (if applicable) | For reservation verification | | ID proof and passport-size photos | Admission formalities | | Funds for Rs. 98,200 (admission) | To confirm seat quickly |
Academic plan to hit CGPA ≥ 7.5 in college: - Prioritise core courses that carry high credits each semester. - Seek research assistant roles to deepen understanding of applied topics. - Avoid backlogs by addressing weak subjects early; use peer tutoring and faculty office hours. - Pick final-year project aligned with ISRO priorities if you plan the ISRO route.
Student life, research and gaps to investigate before you join
What public data does not show clearly: details on student clubs, lab-by-lab research output, faculty profiles and active projects. These affect day-to-day learning and networking.
Questions to ask on campus visits or online calls: - Which labs are accessible to undergraduates for project work? - How many faculty supervise undergraduate projects and what are their research areas? - Are there active student clubs for rocketry, satellite design, coding or data science with industry ties? - What internships or MOUs with ISRO centres and NewSpace companies exist?
Why this matters: a strong placement or ISRO outcome depends on hands-on projects, faculty mentorship and internship exposure — not only on brand or rank.
Alumni outcomes and next-step careers beyond ISRO
Alumni footprint (reported): 3,540 alumni, with about 89% working in India and 11% abroad. IIST graduates pursue different paths: - ISRO/DoS centre roles (core absorption pipeline) - NewSpace startups and private aerospace firms (Skyroot, Agnikul, private contractors) - R&D labs and government organisations - IT and product roles (for CSE/Data Science graduates) - Higher studies in India and abroad (a steady chunk choose M.Tech/M.S./PhD)
The placement and median salary numbers support diverse career choices: median outcomes are around Rs. 12 LPA , which is competitive for both industry and funding for higher studies.
