Dear Aspirant,
In most of the general cases the diploma is considered equal to the 12th in terms of eligibility criteria. Like the eligibility defined will be like marks in 12th or equivalent/diploma. However, there might be some sectors which wants you to have a 12th for sure. In engineering sectors, mainly the diploma will do, but make sure to have atleast 60% marks in your diploma.
Hope this helps. Thank you.
