Thus this experimental study reports on a 2-month classroom investigation, exploring the Multi- Authentic Materials (aural, visual printed) to develop Iranian learners cultural intelligence. 60 intermediate females after taking the placement test randomly were assigned to four groups, one control group receiving non-authentic material designed by the teacher based on the course book subject and three experimental groups receiving M-authentic materials besides the textbook. The researcher used the aural materials like news and podcasts in aural authentic class, the visual materials like magazines or newspapers pictures and mute video clips in visual authentic class, and printed materials like newspapers and websites in printed material class. The cultural intelligence was operationalized with Ang et al. (2007) questionnaire.
