California's public colleges and universities are among the best, from the talent evident in the students to the groundbreaking research conducted by world-renowned faculty. They are also some of the most diverse in the nation. Left out from serving in vital positions of leadership, however, is a proportional representation of Asian Americans, Native Hawaiians, and Pacific Islanders (AANHPI), African Americans, American Indians and Alaska Natives (AI/AN), and Latinx. Students from these groups are the new majority attending our colleges and universities but experienced and credentialed professionals from these same groups are distinctly underrepresented when it comes to holding faculty and leadership positions in California's public colleges and universities. "Left Out: How Exclusion in California's Colleges and Universities Hurts Our Values, Our Students, and Our Economy" recognizes that a more culturally competent workforce is essential to meet the needs of California's future economy. The University of California (UC), the California State University (CSU), and the California Community Colleges (CCC) will be required to educate and produce the workforce of tomorrow. The challenge for higher education is having the capacity, the internal competence, and the commitment to produce a college-educated workforce that is representative of the state's population diversity when their own leadership and faculty ranks are far from diverse.
