The certifications provided by NISM, NSE, and BSE are for educational purposes. They are valuable in the sense that it confirms your awareness about the particular segment.

Example: If you have cleared the NISM Series VIII exam, then it shows that you have enough knowledge about the equity derivatives segment and are qualified to be a dealer. But that is the extent of the matter. It does not certify that you know everything about equity derivatives.

• They are mainly useful to develop functional knowledge about stock markets in India. 
• It increases your understanding of how the markets work and hence improves your knowledge.
• These certifications are only useful for regulatory compliance purposes.

Like every course, it will teach you all the basics that you need to know. It will open up a lot of options. But practical knowledge and experience are always valued more than certificates.
