Minimum Marks Required

Important Notes on Educational Qualification

• If a university mentions both CGPA and percentage of marks in the degree certificate or consolidated mark sheet, at least one criterion (either CGPA or percentage) should meet ISRO's eligibility norms.
• If a university mentions only CGPA, that CGPA must meet DOS/ISRO's eligibility criteria. Converting CGPA into a percentage of marks to decide eligibility is not permitted, even if the university has prescribed a conversion formula. The same criteria apply, with necessary changes, where only a percentage of marks is mentioned.
• Rounding-off of marks is not allowed.
• Candidates holding degrees from foreign universities should produce the equivalency certificate issued by the Association of Indian Universities (AIU), New Delhi at the time of the Personal Interview.

Dual / Integrated Degree Holders

• Where the certificate mentions CGPA or percentage separately for graduation and post-graduation, the graduation and post-graduation CGPA or percentage will be reckoned as per the existing procedure.
• Where a single CGPA or percentage applicable to the entire course is mentioned, that final figure will be used to decide eligibility.
• Where the university does not prescribe any CGPA or percentage in the dual/integrated degree certificate, the cumulative CGPA or percentage in the final/consolidated mark sheet for the entire course will be used.
• These criteria apply uniformly, whether or not a university prescribes a formula to derive the CGPA or percentage for graduation or post-graduation.

LPSC Scientist Engineer Age Limit

The maximum age limit for all three posts is 30 years as on 13.10.2026.
