IÉSEG's diplomas will be recognised as real degrees in other countries. It's only worth the investment if it's the best identifiable choice for your goals. I can't think of any goals for which IÉSEG is the best choice. What are your goals? 

If you want to work in France, learn French and study in French. 

It's a triple-accredited school so it will have networks across all the accreditation networks and will provide a reputable education.<br><br>But whether it's appropriate for your goals is another question. A stronger school (like HEC Paris or Insead) will have much more robust networks and job opportunities, especially outside of France.&nbsp;<br><br>If you do want to work in France after graduation, you should already have a good command of the French language. I could see the case for a French-speaker doing an MBA at IÉSEG to transition into the country - it's probably not the best option but it could work.&nbsp;

There's no specific networking between triple crown schools. In specific topics, for example PhD hiring, it's an advantage. But someone from another triple crown school won't care. In the UK, for example, there's a bit of a network for graduates from the various grandes ecoles.&nbsp;
