You know the drill... Each year, Adweek assigns a grade to advertising agencies of note. It's kind of like Bloomberg's grading system for the New York Public Schools. This year, the magazine cut their list from 10 agencies to just 8. They arrived at their final mark by considering several factors: "global revenue percentage gain (taking into account the size of the shop), revenue/staff ratio and how well a shop did at accelerating revenue growth faster than staff expansion." The shops were also graded on their management practices, creativity, strategy and their use of social networks, mobile and smart use of technology tools. Here's the final report card:
