This study examined and compared language ideologies and attitudes among dual language program (Spanish-English) graduates regarding their use of Spanish and perceptions of their bilingual education experience through surveys and semi-structured interviews. Drawing from the theory of ideology, data was analyzed using both quantitative and qualitative methods. Surveys were divided into two sections and contained 30 Likert-style items related to participants' attitudes regarding Spanish, English, bilingualism and their experiences in the dual language program. Interviews, which were 40-60 minutes in length, were coded in two cycles based on general themes related to dual language graduates' experiences in the dual language program and language attitudes and ideologies. Patterns among codes were identified, analyzed and compared with quantitative findings to create major themes. Findings reveal that graduates generally consider themselves bilingual and had both positive and negative experiences in the program. Additionally, dual language graduates exhibit conflicting attitudes and ideologies regarding monolingualism, standardization and the value of bilingualism. Finally, results indicate a difference in the experiences of the Latinx and non-Latinx students, which have implications regarding the equity of the dual language program. Findings from this study give insight into the experiences of dual language graduates, an area that has received little attention, and provides insight into the issues regarding educational and attitudinal outcomes in bilingual contexts, specifically in dual language programs. Pedagogical implications are discussed as related to the most salient themes identified in this research. [The dissertation citations contained here are published with the permission of ProQuest LLC.
