Commissioned by the Southern Ute Tribal Council and coordinated by the Education Division of the tribe, this study was undertaken to collect and analyze data relating to achievement patterns of Native American, Hispanic, and Anglo children in the public school system in Ignacio, Colorado, The major objective of the study was to determine if differences existed in achievement levels of the three ethnic groups in elementary, junior high, and senior high schools and if differences were found, which demographic, attitudinal, and cultural variables were associated with the differences. A self-inventory was completed by 364 students (primary, 109; intermediate, 66; secondary, 189). A random sample of 10 Ute, 10 Hispanic, and 10 Anglo parents of high school students were interviewed. The basic findings of the study revealed that achievement differences did exist between the three ethnic groups. These differences were associated with three factors--school attendance, self concept, and parent attitudes towards the school. Eight recommendations were presented to the Ute Tribal Council for consideration in reference to this study. (ERB)
