Hello aspirant.

ESIC quota is for candidates whose parent is registered under the scheme of ESIC- Employee State Insurance Corporation and is an insured state person. All employees working in an institution and getting "gross salary" below INR 21000 are eligible for ESIC. Thus, if you are a ward of ESIC employee, you can apply for ESIC quota.
