Some firms moved down. But they all moved. None of the firms on the 2010 A-List returned to the same spot this year. Whether it was a result of a firm’s spike in its associate satisfaction score, or a drop in its revenue per lawyer, the 2011 A-List was all about volatility.

Take the top of the leaderboard. Hughes Hubbard & Reed climbed into the highest spot after two years in the number two position behind Munger, Tolles & Olson. Munger was among the 12 firms on last year’s list that saw their rankings decline this year. The Los Angeles–based firm, which has held the top position for the past three years, didn’t fall far. Munger took the second spot on the 2011 list, falling short of New York–based Hughes Hubbard’s total score by just three points (1,141 vs. 1,138).
