🏢 Major Participating ISRO Operational Centers Across India
ISRO recruitment is conducted either through the ISRO Centralised Recruitment Board (ICRB) for nationwide multi-center vacancies or through dedicated center-specific notifications released by autonomous space facilities. Candidates selected may be posted at any of the following research facilities based on project requirements:
1. URSC & ISTRAC (Bengaluru, Karnataka)
U R Rao Satellite Centre is the lead facility for design, fabrication, testing, and integration of all Indian satellites and deep-space communication telemetry.
2. VSSC (Thiruvananthapuram, Kerala)
Vikram Sarabhai Space Centre is the premier rocket development center responsible for PSLV, GSLV, LVM3, and Next-Gen Launch Vehicle (NGLV) systems.
3. SDSC SHAR (Sriharikota, Andhra Pradesh)
Satish Dhawan Space Centre is India’s spaceport hosting dual launch pads, solid propellant production plants, and vehicle assembly buildings.
4. LPSC & IPRC (Valiamala & Mahendragiri)
Liquid Propulsion Systems Centre and ISRO Propulsion Complex test and assemble cryogenic engines, semi-cryogenic rocket stages, and spacecraft thrusters.
5. SAC (Ahmedabad, Gujarat)
Space Applications Centre specializes in electro-optical satellite payloads, synthetic aperture radars, atmospheric sensors, and transponders.
6. NRSC (Hyderabad, Telangana)
National Remote Sensing Centre manages geospatial mapping, disaster management support, Bhuvan GIS infrastructure, and satellite data dissemination.
🎓 Prescribed Educational Qualifications & Age Benchmarks
Eligibility for ISRO posts is strictly scrutinized during online document verification. Unlike general government exams where a 50% pass mark suffices, ISRO mandates strict minimum first-class academic benchmarks:
A. Scientist / Engineer 'SC' (Level 10)
- Degree: B.E. / B.Tech or equivalent in Mechanical Engineering, Electronics & Communication, Computer Science, Electrical, or Civil Engineering.
- Minimum Percentage: An aggregate minimum of 65% marks (average of all semesters) OR CGPA of 6.84 / 10 from an AICTE/UGC recognized university.
- Final Year Students: Candidates appearing in their final semester can apply provided they produce their provisional degree certificate with the required percentage during the document verification stage.
- Age Limit: 18 to 28 years for General / Unreserved candidates. Relaxations apply: +3 years for OBC, +5 years for SC/ST, and applicable guidelines for PwD & Ex-Servicemen.
B. Technical Assistant / Scientific Assistant (Level 7)
- Degree: First Class 3-Year State Board Technical Education Diploma in Mechanical, Electrical, Electronics, Civil, or Computer Science.
- Scientific Assistant: First Class B.Sc. Degree in Physics, Chemistry, Mathematics, or Computer Science.
- Age Limit: 18 to 35 years for UR category candidates (+3 years for OBC, +5 years for SC/ST).
C. Technician 'B' & Draughtsman 'B' (Level 3)
- Qualification: SSLC / Matriculation / 10th Standard Pass + ITI / NTC / NAC in respective trades (Fitter, Electronic Mechanic, Electrician, Machinist, Welder, Turner, Plumber, Draughtsman).
- Age Limit: 18 to 35 years for UR category candidates.
📝 Official Examination Pattern & Negative Marking Blueprint
The revised ISRO examination blueprint consists of two clear evaluation phases designed to test fundamental engineering concepts, analytical speed, and professional competency:
CBT Exam Architecture for Scientist/Engineer 'SC' (Total Duration: 120 Minutes)
Part-A: Core Discipline (80 MCQs / 80 Marks)
• 75% focused strictly on the core engineering syllabus (GATE-equivalent depth).
• 25% testing allied engineering application concepts.
• +1 Mark for correct answer; -0.33 Marks for wrong answer.
Part-B: Aptitude & Reasoning (15 MCQs / 20 Marks)
• Numerical reasoning, spatial ability, logic, and comprehensive data interpretation.
• Tests speed and real-world cognitive problem-solving.
• Zero negative marking in Part-B.
Passing Threshold: Minimum 50% in Part-A and 50% in Part-B for General candidates (40% for reserved categories). Shortlisted candidates in 1:5 ratio are summoned for the in-person Technical Interview.
💰 7th CPC Salary, Allowances & Space Research Perks
An appointment at ISRO comes with world-class job security, advanced research autonomy, and lucrative central government remuneration under the 7th Central Pay Commission:
Monthly Remuneration Breakdown for Scientist / Engineer 'SC' (Level 10)
Basic Pay
₹56,100
Dearness Allowance (50%)
₹28,050

Approximate Net In-Hand Take-Home (after NPS, CGHS & Insurance deductions): ₹96,000 – ₹1,02,000 / month plus Department of Space residential quarters, subsidized medical facilities (CHSS), and annual research performance-related incentives (PRIS).
🎯 Proven Preparation Strategy for ISRO Written Examination & Interview
-
Master Fundamental Engineering Core: ISRO tests direct fundamental conceptual clarity rather than long computational calculations. Focus on Standard Textbooks and previous 10–15 years of ISRO ICRB original question papers.
-
GATE Alignment: The level of difficulty in Part-A closely matches GATE 1-mark and selected 2-mark conceptual problems. Practicing GATE PYQs in Thermodynamics, Fluid Mechanics, Signals & Systems, Digital Electronics, and Data Structures is essential.
-
Time Management & Pacing: With 95 questions to be answered in 120 minutes, candidates have approximately 75 seconds per question. Practicing timed Computer-Based Tests (CBT) on TargetExams trains your instinct to avoid question traps.
-
Strict Negative Marking Discipline: Since each wrong answer deducts 0.33 marks, guessing on uncertain technical questions severely damages the merit cut-off. Maintain a target accuracy above 85%.
-
Prepare Final Year Project for Interview: The technical interview carries a decisive 50% weightage in final selection. Interview boards dive deeply into your B.Tech/Diploma final year capstone project, experimental validation, and real-time engineering troubleshooting.
