There's an MBA program search at http://www.find-mba.com/search

Generally, because the MBA is normally one year here, there are not many accredited MBAs with specialisations in the UK.

Thank you.

Can you please let me know if Greenwich school of Management is good enough?

If you want to work in Britain you'll have a much better return on your investment if you attended a university, and ideally one which is internationally accredited, rather than a for-profit private school.

Agreed.

There aren't many reputable MBA programs in the UK with a concentration in human resources. This is because human resources isn't really that technical, and is usually adequately covered in the core curriculum of an MBA program. In my opinion, a better option than the Greenwich program would be to do a general MBA from a ranked business school.

For example, in Bradford's program, you could take a few human-resources related electives. Also, human resources makes up a chunk of the core curriculum in the programs at Cass and Durham.

Whenever I see the phrase 'an MBA in...' I think the person using those words misunderstands the point of an MBA. It's supposed to be a generalist course on managing businesses and other organisations, not a masters-level program in a specific discipline.

With most MBA programs it's possible to achieve some degree of concentration in broad areas through a choice of electives and/or independent projects. This may appeal if your current or intended career is in a particular area, such as HR. Equally, a good MBA course should expose you to other disciplines and industries, which may lead you to follow a different path.
