This study investigated language attitudes toward Valencian Catalan and Castilian among university affiliates in Castellón de la Plana, Spain. One hundred informants completed an online survey regarding attitudes toward and uses of Valencian and Castilian in various situations. The results were first analyzed globally, then again based on the independent variables of age, sex, and mother tongue. The findings suggest that overall, informants held positive attitudes toward Valencian and Castilian and believed that it was important that the local language be preserved and passed down to the next generation. University-aged participants, those whose first language was either Valencian or both Valencian and Castilian, and females tended to hold slightly more positive attitudes toward Valencian than other groups.
