Unfortunately, this means my answer to your question is that I really can't tell how well recognized the NCC certifications might be. I'd suggest that you might want to contact local IT companies, staffing or recruitment firms, and even local colleges and universities to get their take on this interesting set of offerings. I see nothing inherently questionable or wrong with it, but I don't see ringing endorsements for it in the trade or business press, either.
One more thing: Since the ICDS is accepted as a pre-requisite for advanced degrees or academic training, it's at least as good as other computer science or computer studies diplomas available. Given its broad international focus, coverage, and availability, it's probably worth investigating further.
Sorry I couldn't be of more help in this instance.
