Shoosmiths has topped the UK's leading diversity table for the second year running.
The national law firm finished top of the 2012 Black Solicitors' Network (BSN) Diversity League Table (DLT), scoring a diversity quotient of 896 from a possible 1,000.
Shoosmiths finished top last year, and was also ranked first in 2006.
Fifty per cent of the quotient score reflects rankings in six demographic league tables created for gender and ethnic diversity at partner, associate and trainee level.
The remaining 50% comes from responses to questions on five areas of diversity policy and practice: monitoring; leadership and internal policy/strategy; external 'face'; staff development and support; and recruitment, promotion and retention.
Chief executive Claire Rowe said: "It's easy for organisations across all sorts of sectors to talk about diversity, but quite another matter to actually do something about it. Topping the BSN table again is proof that Shoosmiths embraces diversity, and has it as an integral and important part of its working culture.
"This comes in an exceptional 12 months for us, what with our move into Scotland, our rebrand, a raft of partner promotions, and heavyweight lateral partner hires."
HR director Louise Hadland added: "Diversity is deeply embedded in the culture here at Shoosmiths, and is something we champion continually. "
The DLT is the legal profession's leading diversity publication, produced in association and consultation with the Law Society and the Bar Council.
