The recognition of English as International Language has influenced the criteria of embedding cultural content in ELT textbook. Its status, then, emphasizes the relevance of World Englishes to ELT practices. Textbook as one of the crucial elements in ELT practices should load the criteria. Therefore, the concept of World Englishes which includes inner, outer, and expanding circle should be taken into account as the reference of cultural content in ELT textbook. The objective of the study is to explain the presentation of cultural aspects in English as International Language perspective and the type of cultural load in the orientation of communication and knowledge. This research is categorized as content analysis since it is aimed at evaluating textbook investigating cultural content. The data were gathered by using the checklist containing the cultural aspects. The result shows that the three series of Interactive English textbooks expose the cultural content of inner, outer, and expanding circle of English in appropriate presentation. The culture of inner circle is presented lower than that of outer and expanding circle. The most essential is that the presentation of outer and expanding circle which contains local culture is exposed dominantly. However, for the other case, not all series of Interactive English textbook present the cultural load in communication-based orientation. Two series of Interactive English textbooks namely IE 1 and IE 3 more reflect knowledge-based orientation than communication. This research is expected to have significances specifically in pedagogical field. It is expected help teachers take into account the cultural values in the teaching and learning process and help them have a point of view about the appropriateness of a textbook in terms of cultural content. By teacher’s consideration, it can also help learners improve their cultural awareness and communicative competence.
