ORLANDO, Fla. (AP) — The WNBA has received the first A-plus given in Richard Lapchick's annual diversity report card on race and gender.

The Institute for Diversity and Ethics in Sport study, which grades professional leagues on the number of participating women and minorities, shows women own three WNBA teams, up two from 2007 and one the previous year.

The number of minority head coaches and players increased, but there was a slight decrease in women and minority assistant coaches.

Lapchick, director of the University of Central Florida institute, said the WNBA has long led the way in his studies and benefited from its relative youth. The league began play in 1997.

"They started at the same time the (NBA) began its diversity initiative, so the WNBA was able to include a good pool of candidates from the very beginning," Lapchick said.

Carla Christofferson and Katherine Goodman own the Los Angeles Sparks, Colleen J. Maloof and Adrienne Maloof-Nassif own the Sacramento Monarchs, and the Seattle Storm's owners are Anne Levinson, Ginny Gilder, Dawn Trudeau and Lisa Brummel.
