More than ever, law firms are measuring representation of women in their lawyer ranks in concrete terms.

Corporate legal departments are calling for more diversity in the legal industry—not just requesting it but actually requiring law firms to measure and monitor their diversity and inclusion of women and minorities. Clients want to know that the firms who serve them are inclusive—or they will not engage them. As a result, firms are increasingly measuring and reporting these important statistics, and paying attention to their performance.

The result: This year's Women in Law Scorecard rankings includes 28 law firms that did not participate in last year's ranking. And three firms new to the survey entered straight into the top 10.
