Eligibility Criteria
ISRO is extremely strict regarding educational qualifications. For Scientist and Engineer roles, candidates must possess a first-class degree. For Technicians, the ITI certification must be from a NCVT/SCVT recognized institute.
- Scientist/Engineer ‘SC’: M.E/M.Tech or equivalent in the relevant field (Mechanical, Electronics, Structural, etc.) with a minimum aggregate of 60% OR B.E/B.Tech with a minimum of 65% marks/6.84 CGPA.
- Technical Assistant: First Class Diploma in Engineering in the relevant discipline (Mechanical/Electrical/Electronics/Civil/Chemical).
- Technician ‘B’: SSLC/SSC (10th) pass plus ITI/NTC/NAC in the respective trade (Fitter, Electrician, Electronic Mechanic, Machinist, etc.).
- Fireman ‘A’: 10th Standard pass. Candidates must meet the prescribed Physical Fitness and Endurance standards.
- Cook/Driver: 10th Standard pass with relevant experience (5 years for Cook, 3 years for Driver) and a valid driving license for the respective vehicle category.
Age Limit (as of Nov 14, 2025): For most technical posts, the upper age limit is 35 years. For Fireman and Driver roles, it is typically 25 to 30 years. Standard relaxations apply (5 years for SC/ST and 3 years for OBC).
Selection Process
The selection process at ISRO SDSC SHAR is designed to be purely meritocratic. It typically involves a screening process followed by two major stages.
- Written Test: This is an objective-type exam conducted either in Computer Based Test (CBT) format or OMR format. It tests the core technical competence of the candidate.
- Skill Test (for Assistants/Technicians): Candidates who clear the written test are called for a skill test in a 1:5 or 1:10 ratio. The skill test is qualifying in nature (Go/No-Go basis).
- Interview (for Scientist/Engineer): For Group A posts, the written test is followed by a personal interview. The final selection depends on both written and interview performance (often 50:50 weightage).
- Physical Endurance Test: Specific only to Fireman 'A' posts, involving running, rope climbing, and long jump.
Exam Pattern and Detailed Syllabus
Preparation for ISRO requires a focus on core engineering fundamentals. Unlike other government exams, ISRO does not place high weightage on General Awareness; instead, it focuses deeply on technical subjects.
Scientist/Engineer 'SC' Syllabus: Focus on GATE-level syllabus. Major topics include Strength of Materials, Thermodynamics, Fluid Mechanics, Control Systems, Signals and Systems, Electromagnetic Theory, and Digital Electronics. The exam usually consists of 80 objective questions to be solved in 90 minutes.
Technical Assistant/Technician Syllabus: The syllabus is based on the Diploma or ITI curriculum respectively. For Technicians (e.g., Fitter), questions will focus on workshop calculation, safety, measurement, and specific trade tools. For Technical Assistants, the focus is on standard polytechnic curriculum. There are usually 80 MCQs with 1 mark each and 0.33 negative marking.
Physical Standards for Fireman
Fireman 'A' candidates must meet the following mandatory physical requirements to be eligible for the written test results to be considered.
- Height: Minimum 165 cms (Relaxation for Hill tribes).
- Weight: Minimum 50 kgs.
- Chest: 81 cms (Normal) and 86 cms (Expanded).
- Distant Vision: 6/6 without glasses.
- Endurance Test: 100-meter run in 15 seconds, climbing a 5-meter rope using hands only, and a long jump of 3.8 meters in 3 attempts.
Expert Preparation Strategy for ISRO SHAR
To succeed at ISRO, candidates must change their mindset from competitive exam "tricks" to "conceptual depth."
Master the Fundamentals: ISRO written tests are known for asking "why" rather than just "what." For example, instead of just solving a circuit, you might be asked about the underlying semiconductor physics. Ensure your basics from the first and second years of engineering/diploma are rock solid.
Previous Year Papers: ISRO center exams (VSSC, LPSC, SDSC, URSC) often have a similar level of difficulty. Solve at least the last 10 years of papers from all ISRO centers. This will give you a clear idea of the "favorite" topics of ISRO scientists who set the paper.
Skill Test Practice: For Technicians and Technical Assistants, the skill test is crucial. If you are an Electrician, practice wiring circuits and using multi-meters. If you are a Mechanical technician, ensure you can operate lathes and milling machines with precision. Many candidates score full marks in the written test but fail the skill test because they lack hands-on experience.
Best Books for Preparation
Choosing the right books is half the battle. Below are the recommended titles for different levels of the ISRO SDSC SHAR exam.
| Scientist/Engineer: GATE previous year solved papers (Made Easy/ACE Academy) and standard textbooks like Morris Mano (Digital) or B.C. Punmia (Civil). |
| Technical Assistant: Objective Mechanical Engineering by R.S. Khurmi or Diploma-specific guides by G.K. Publications. |
| Technician 'B': ITI Trade theory books by Arihant Publications or Asian Publishers (Trade specific). |
| Mathematics: Higher Engineering Mathematics by B.S. Grewal (Essential for Scientists). |
