In-house attorneys who went to a Top 50 law school earn an average of 30% more than those attending schools ranked 100 or lower. If they went to a Top 50 law school and worked at an Am Law 50 law firm, they earned 76% more than those who didn’t.

Those were among the findings from the recruiting firm BarkerGilmore’s recently released annual compensation report, which was based on responses from 3,800 U.S.-based corporate counsel, 48% of whom attended a top-50 U.S. law school.
