Hi Aspirant,

NIOS degree are recognized by the Ministry of Human Resource and Development (HRD), Government of India. So, your NIOS qualification is valid for any kind of jobs until and unless the job is private and all the terms and conditions are dependent on the owner. And since you are talking about BPO(Business Process Outsourcing) jobs, so now it all depends on the owner of company for whom you want to job. So, do check the eligibility criteria and be clear about your NIOS certification before taking up the job.

Hope this helps.

Good luck!!
