The purpose of this study was to assess students' attitudes toward several aspects of biliteracy within the context of a dual immersion program. Attitudes toward perceived competencies in reading in two languages, along with the social and personal values of literacy in each language (English and Spanish), and the personal and social value of biliteracy were measured by a survey and analyzed for similarities and differences in beliefs in eight categories. Findings reveal students' attitudes toward the social and personal values of literacy in both languages. Responses were analyzed by grade level, language group, and language group/grade level. When responses to specific questions were analyzed by grade level, a developing trend among students was noted. (Contains 1 figure and 13 tables.)
