The purpose of the present cross-cultural study was to explore the relationships of second and foreign language teachers' and students' attitudes towards Computer-Assisted Language Learning (CALL) in terms of their gender, age group, and educational level in two countries, Spain and Iran. The study was based on a sample of 318 language teachers and 307 language students in Iran and Spain. Data collection was carried out through two online questionnaires (108 items) for both teachers and students. To make a sound decision, the researchers decided to utilize the Delphi methodology, which was originally established in order to diagnose the beneficiary of technologies. In the data analysis phase, descriptive, t test and one-way ANOVA analyses were performed to find the answers of the research questions. The findings of the study revealed that there is no difference between the attitudes of Iranian and Spanish towards CALL in terms of gender, age and educational matter. Finally, pedagogical implications and recommendations for further research are presented.
