President Joe Biden’s judicial appointees are changing the face of the federal bench, but there’s one aspect that has largely stayed the same over time: Harvard and Yale remain the most common law schools that judges attend.

An American Bar Association report released Thursday found that, as of March, there were 111 federal judges with law degrees from Harvard and 72 from Yale. Altogether, 232 judges have Ivy League law degrees, representing 18% of the U.S. judiciary.
