Law360 released its second annual report of the 100 best United States law firm for women in April 2016. It based its ranking criterion on the firm’s female attorney representation at the partner and nonpartner levels, and its total number of female attorneys.

Also in 2016, Law360’s Glass Ceiling report found that women made up 34% of all U.S. attorneys and only 22% of partners in the U.S. Law firms surveyed by Law360. These numbers are on track with NALP’s numbers, which found that women make up 33% and 22% of partners and associates in U.S. law firms.

The ranking factors employed by Law360 are, at best, narrowly focused.
