Elected in November 2004, Representative Diaz has been a champion of education and child care issues. She currently serves as chairwoman of the Legislative Commission on Child Care, which has successfully shed light on the policy work surrounding changes in child care through the commissions annual Child Care Awareness Day event at the Rhode Island State House. She is also a member of the House Commission to Study Public Higher Education Affordability.
Her most recent victory stemmed from her bill enacted in 2012 which prevents children from receiving out-of-school suspensions for attendance issues. This year, the Rhode Island chapter of the American Civil Liberties Union (ACLU) released a report, stating: "In large part because of this new law, nearly 1,700 fewer students were suspended during the 2012-2013 school year than in 2011-2012." It also marked the first time since at least 2004 that the overall number of students with suspensions dropped below 10,000.
Representative Diaz was appointed as vice-chairwoman of the Rhode Island Democratic Party in 2008. She is a native of the Dominican Republic and serves as a member of several political organizations and groups, including the National Association of Latino Elected Officials, Women in Government, National Hispanic State Legislators and the Rhode Island Legislative Black and Latino Caucus.
Representative Diaz will retain her positions as deputy chairwoman of the House Committee on Health, Education and Welfare, and secretary of the House Rules Committee.
