The "Using High School and College Data to Predict Teacher Candidates' Performance on the Praxis at Unibetsedåt Guåhan (University of Guam)" study examined which student demographic and academic preparation characteristics predict passing the Praxis® Core test and each of its subtests at the Unibetsedåt Guåhan (University of Guam, UOG) School of Education. This information is needed to increase admissions to the School of Education and, ultimately, to increase the number of available teachers. The study findings have several implications for intervention plans at both the secondary and postsecondary levels. Although students must pass all three Praxis® subtests to be admitted to the teacher preparation program at the School of Education, examining student performance on each subtest can help stakeholders understand the content areas in which students might need more support. In the long term, preparing more prospective teachers for the Praxis® Core test might increase program enrollment, which in turn might increase the on-island hiring pool. This document presents the following three appendixes that accompany the study: (1) Unibetsedåt Guåhan (University of Guam) admissions requirements and research on the Praxis® Core test; (2) Methods; and (3) Supporting analysis.
