In this fifth brief in "Excelencia" in Education's series on Hispanic-Serving Institutions (HSIs) the focus is on the methods and strategies that are producing successful results in a growing sector of colleges and universities we call, "Emerging" Hispanic-Serving Institutions. These Emerging HSIs are institutions that currently do not meet the federal threshold of 25 percent Latino enrollment to be classified as HSIs, but have Latino enrollments ranging between 12-24 percent. These institutions have the potential to be eligible for the designation as an HSI in the coming years. This brief is the first formal appraisal of this important group of institutions and the role they play in serving Latino students. Specifically, this brief examines Emerging HSIs--institutions that do not yet meet the HSI enrollment threshold of 25 percent, but which are within the critical mass range of 12-24 percent and have the potential to become HSIs in the next few years. The brief integrates national data with data from a web-based survey and four case studies to examine Emerging HSIs' awareness of Latinos as a definable group on their campus, as well as changes in institutional practices to better serve their Latino students. The four Emerging HSIs studied in this brief include: Loyola Marymount University (CA), Palm Beach Community College-Lake Worth (FL), Texas State University-San Marcos (TX), and Metropolitan State College of Denver (CO). Appended to this report are: (1) List of Emerging Hispanic-Serving Institutions (HSIs): 2006-07; and (2) Survey of Emerging Hispanic-Serving Institutions: Data Collection Process.
