Core Educational Qualifications
The foundational requirement for aspiring Scientist/Engineer 'SC' candidates at ISRO is a strong academic background in engineering. Applicants must possess a B.E., B.Tech, or an equivalent qualification in a relevant discipline. A consistent and high
level of academic performance is non-negotiable; candidates are required to have secured an aggregate minimum of 65% marks across all semesters, or a Cumulative Grade Point Average (CGPA) of 6.84 on a 10-point scale. This stringent criterion ensures that only candidates with a solid technical foundation are considered for these critical roles in India's space program. The degree must be from a university or institution recognized by the Indian government.
Accepted Engineering Disciplines
ISRO's recruitment drives are targeted toward specific engineering fields that are crucial for its various projects and missions. The latest notifications specify vacancies in several key areas. The major disciplines typically include Electronics and Communication, Mechanical Engineering, and Computer Science. Other vital fields such as Civil Engineering, Electrical Engineering, and even specialized areas like Refrigeration and Air Conditioning and Architecture are also part of the recruitment, depending on the specific needs of ISRO's various centers. For example, recent recruitment has called for 34 positions in Electronics, 26 in Mechanical, and 13 in Computer Science, highlighting the high demand in these core areas. Aspiring candidates should always check the official notification for the exact list of eligible disciplines and their allied branches for any given recruitment cycle.
The Role of GATE Scores
In a significant part of its modern recruitment strategy, ISRO uses the Graduate Aptitude Test in Engineering (GATE) score as a primary shortlisting tool. Candidates are often required to have a valid GATE score from recent years, such as 2025 or 2026, in the paper corresponding to their engineering discipline. It's important to note that ISRO shortlists candidates based on their GATE score, not their rank or raw marks. This score-based shortlisting is followed by a personal interview, with the final selection giving equal 50% weightage to both the GATE score and the interview performance. However, ISRO also reserves the right to conduct its own written test for some vacancies, so applicants must carefully read the notification to understand the selection process for the specific post they are interested in.
Age Limit and Relaxation Rules
The age limit for applying for the Scientist/Engineer 'SC' position is another critical factor. For general category candidates, the upper age limit is typically set at 28 years as of the closing date of the application period. However, in line with government regulations, there are provisions for age relaxation for candidates from reserved categories. Candidates belonging to Other Backward Classes (OBC) are given a relaxation of up to 3 years, making their upper age limit 31 years. For Scheduled Castes (SC) and Scheduled Tribes (ST) candidates, the relaxation is up to 5 years, extending their upper age limit to 33 years. Ex-servicemen and Persons with Benchmark Disabilities (PwBD) are also eligible for age relaxation as per the prevailing Government of India orders.
How to Apply and Final Considerations
All applications for ISRO recruitment must be submitted online through the official ISRO website, www.isro.gov.in. The application window is time-bound, with recent notifications showing an application period from late July to mid-August. Candidates must ensure they have a valid email ID and mobile number for registration. During the application process, they need to fill in personal details, academic qualifications, and their valid GATE score information. After filling out the form, applicants upload the required documents and pay the application fee, which is around ₹250 for unreserved candidates. It is crucial to carefully preserve the registration number provided after submission for all future correspondence.
