If I have the certificate of EWS in 2021-2022 for ssc steno 2020 then am I eligible at the time of DV
Yes,it is eligible
Generally,ssc conducted all exams ssc CGL ssc chsl SSC steno accepted same certificate for all. SSC provided specified performa of EWS category which is applicable in all ssc exams. central government EWS certificate is same as SSC performa.
Ssc accepted EWS certificate only if it is made before 1 year of crucial date i.e last date of Application Form not older than this accepted by SSC.
For the Candidates who fill form for 2020 and produce 2020-2021 EWS certificate it is provision ally accepted by filing crucial date form.so you can submit.
hope it helps!!
