Hello,
IIM's are still in the phase of earning a recognition for their 1-year program. I would rank ISB as the top most choice for the same. It is ranked under top 30 colleges for doing MBA from around the world. The program, course structure, faculty and post-MBA placements are excellent in ISB and have been a threat to all major IIM's one year MBA programs.
While getting into ISB's one year program is extremely difficult, it is comparatively easy to get into EPGP of IIM B. The second choice would be SP Jain. While ISB is pretty much ahead of SP Jain with respect to the above parameters, SP Jain is slowly catching up with the top colleges around the world. SP Jain is too ranked under top 30 colleges in the world to do an MBA from.
If you are really looking for a one year MBA, then please consider ISB and SP Jain as your top choices, and in an extreme case, consider IIM B EPGP.
