Arizona State University has developed a new model for the American Research University, creating an institution that is committed to excellence, access and impact. ASU measures itself by those it includes, not by those it excludes. ASU pursues research that contributes to the public good, and ASU assumes major responsibility for the economic, social and cultural vitality of the communities that surround it. ASU offers more than 750 degrees and certificates on four campuses. ASU's historic Tempe campus is the largest and where most of ASU's signature events take place.
