Hii,

The Basic eligibility to get into the ISRo one must possess a graduation degree from Science background. After that apply for ICRB which is a written test to get into ISRO.once you clear the test you would get a interview call and then ISRO. There is also another way to get into ISRO. After your 12th you can write IIST and pursue Btech in that college. ISRO recruits students from this College.
