These are the appendices to the report, "Using High School Data to Predict College Success in Palau" (ED610714). Prior research, particularly for the United States, has shown that earning a community college credential increases an individual's likelihood of gaining stable employment, earning a living wage, and working in a higher-paying job than in a job that requires only a high school diploma. Research on early college success and college completion in the Republic of Palau has been limited, however. The current study is intended to increase Palau Community College administrators' and educators' understanding of the factors associated with early college success and college completion by describing the high school academic preparation variables and other student characteristics of students in Palau who achieved early college success and completed college. This appendix summarizes the research base used in developing this study. Prior research, most of it in the United States, might be only partially applicable to Palau because its education system and student population differ substantially from those of the United States. Despite that limitation, the current study identified college success outcomes and academic preparation and student characteristic variables of interest based on the research literature. The appendices include: (1) About the study; (2) Methods; (3) Supporting analysis; and (4) Other analyses. [For the full report, see ED610714. For the study snapshot, see ED610716.
