"The Academy is going to lead and not wait for the industry to catch up," she said in a statement.
The film academy's 51-member board of governors unanimously approved a series of reforms late Thursday to "begin the process of significantly changing our membership composition," Isaacs said. The number of minorities currently serving as members of the academy has not been revealed.
Several of Hollywood's most prominent African-Americans, including Will Smith and Spike Lee, have said they won't attend this year's Oscars, which is to be hosted by Chris Rock.
Other changes include limiting members' voting status to a period of 10 years, to be extended only if the individual remains active in film during that decade. Lifetime voting rights will be granted only to Academy Award nominees and winners, and to members after three ten-year voting terms. Previously, all active members received lifetime voting rights.
The organization also plans to diversify its leadership beyond the board of governors by adding new members to key decision-making committees, and further diversify its membership with a global campaign to identify and recruit diverse talent.
Reaction came swiftly. Ava DuVernay, director of last year's best picture-nominee "Selma," tweeted that the changes were "one good step in a long, complicated journey for people of color and women artists." She added: "Shame is a helluva motivator."
"Marginalized artists have advocated for Academy change for DECADES," DuVernay wrote. "Actual campaigns. Calls voiced FROM THE STAGE. Deaf ears. Closed minds."
And director Rick Famuyiwa, whose films include "The Wood," ''Brown Sugar" and last year's "Dope" commented: "The devil is in the details."
