Often expressed claims which amounted to a general belief among many of the administrators of the schools of Carbon County were the stimulus for this study. The claims generally expressed were that the Mexican-Indian students of the schools did not have as good ability, did not achieve as well, were poorer attenders, caused a larger amount of difficulty and delinquency and did not adjust to the school society as well proportionately as their co-students of other nationalities. It was stated that while many nationality groups were represented in the school population, that other groups were oriented, assimilated and amalgamated into the mainstream, and seemed to compare favorably, but this was not true of the Mexican-Indian student. It was also a quite common claim that there was little difference between the Mexican- Indian student and others during the early years and up until about the 9th grade but after that a definite contrast appeared and as time progressed the contrast broadened; the Mexican-Indian maturing and marrying earlier, losing interest in school earlier, dropping out earlier, and suffering a greater setback in progress achievement and accomplishment after the 9th grade . It was also claimed that Mexican-Indian family attitudes were not as favorable toward education as others. Originally, it was planned to compare three groups - the Mexican, another nationality group and the main group. This proved not feasible as a third group was difficult, if not impossible, to find in sufficient quantities for statistical comparison within the scope of the study. This partially proved the one claim, that other nationality groups had amalgamated better. It was thus necessary to limit the comparison to the Mexican-Indian and all other students.
