I think the FT ranking is very reliable.

I'd rank them like this, based on generally on reputation and placements (with some caveats):

1. Kellogg
2. Cornell
3. BU

What are your career goals? The Boston program is globally-focused, with a residency in China, so if you wanted to work in an international environment, multinational, etc., this is a good choice. (There's also the IBEAR program at USC Marshall, you might want to check that out.)

Keep in mind that these one-year MBAs are generally looking for people with specific ideas about what they want to do after graduation. You don't get the same breadth in the core curriculum as you would in a two-year program - the Kellogg core program doesn't require any finance or marketing - but you round out the curriculum through electives. There's also not as many opportunities for internships in these and similar programs - Cornell offers a two-week internship, but I'm skeptical of how effective an internship can actually be if it's only two weeks long.

A few other one-year MBA programs you might want to explore:

Emory (Goizueta)
Babson (Olin)
Pepperdine

Thanks, Duncan and Hipster.

I will have to think about my career goals...

Hi Duncan

I am looking to apply for a 1 year course in US, can you help me.

Thanks

Of course. Please read my profile page. I think you can find much of what you want to know by searching the discussion board.

I am a IT professional and want to do a MBA then tell me that a one year MBA or executive MBA is a good option for me in India.

There are three one-year MBAs in India with international accreditation: SP Jain, ISB and IIM-A.

I'd also look at MISB in Mumbai.
