The 1970-71 evaluation of the Grants, New Mexico, Bilingual Education Project is reported through narrative description of tests administered and their results, statistical findings from analyses of variance or covariance of test results, and conclusions and recommendations based on test results. In the evaluation, the 147 students in the experimental and the 35 students in the control group--representing 6 schools and 4 language references (Keresan, English, Spanish, and Navajo)--were given various tests for which a pre-test/post-test measure was used to ascertain significant experimental group gains over an 8-month period: the Southwestern Cooperative Educational Laboratory Test of Oral English Production; the California Achievement Test; the Test of Basic Experiences (a Spanish-language instrument measuring concept comprehension in science, social studies, and mathematics); the Caldwell Test (a Spanish-language instrument for measuring a child's ability to provide responses about himself and his role activities); and the author's Cultural Sensitivity Instrument (a pictorial and manipulatory measure of perceptions and attitudes concerning Anglo Americans, American Indians, and Mexican Americans). Also, a questionnaire was designed and administered to ascertain perceptions and attitudes of school personnel about the bilingual program components. There are 24 tables. (BO)
