A study out this week found women and minorities are making impressive gains in landing general counsel jobs at Fortune 1000 companies. Compared with a year earlier, the number of women in those roles rose 12%, to 331, and the number of Blacks increased 22%, to 60.

Good news, to be sure. But the spurt of progress at the top might not be indicative of what’s happening across entire legal departments, in-house recruiters tell me.
