How to Get Into ISRO Through IIST?
Joining IIAST can lead you to join the ISRO. To be eligible for ISRO recruitment:
It is mandatory to attain at least 7.5 CGPA on a 10-point scale.
Candidates should have no active backlogs.
The medical fitness of the candidate should be as per the ISRO standards.
Selection depends upon the performance of candidates in the technical rounds based on concepts, projects, and role fit.
Eligibility Criteria for ISRO from IIST
Criteria | Requirement | Type | Impact |
Minimum CGPA | ≥ 7.5 (10-point scale) | Primary Filter | Below this → Direct rejection |
Backlogs | No active backlogs | Mandatory | Disqualification even with good CGPA |
Medical Fitness | As per ISRO standards | Qualifying | Required for specific roles |
Interview | Technical rounds | Final Selection | Not all eligible students selected |
Evaluation Basis | Concepts, projects, role fit | Decisive Factor | Determines final absorption |
Why Many Do Not Reach 7.5 CGPA
1. Academic rigor is high
Aerospace + Avionics = very demanding curriculum
Grading is relative and competitive
2. Peer quality is strong
Everyone is from top JEE ranks
So maintaining 7.5 is not trivial
3. No grade inflation
Unlike some private colleges
Evaluation is strict → CGPAs stay compressed
