Hi there,

You are not eligible for the ISRO SDSC Technical Assistant post with a 61% in your diploma. 60% is the minimum requirement for the first class, but to get to the post of  Technical Assistant, you need to meet the specific eligibility that is required in the official recruitment. If you have lower marks than required in the official recruitment notice, you will not be eligible to apply for the written exam. Also, it depends on the discipline of the diploma for which you are applying.

Hope it helps!!!

Hello

You’re most likely eligible because ISRO SDSC usually asks for a “first-class” diploma, which generally means 60 or above.
Since you scored 61, you fall in the qualifying range.
Just make sure your diploma is from a recognised institute.
Eligibility rules can change every year, so always check the latest official notification. You can refer to the link I am attaching for more details.
