Midsize law firms are lagging behind both their larger and smaller competitors when it comes to fostering a diverse workplace. The good news is that they appear uniquely positioned to show real improvements if they choose to do so, according to diversity experts.

At law firms with between 101 and 250 attorneys, just 4.65 percent of partners belonged to minority groups, according to 2011 numbers compiled by NALP, formerly the National Association for Law Placement. Minorities represented 15.05 percent of associates. In both categories, midsize firms had lower minority percentages than law firms of any other size.
