The present study focuses on the critical evaluation of the cultural content incorporated in the 5th and 6th grade English textbooks, which are taught in the Greek state primary school. Given that we are living in the era of increasing globalization, it is deemed essential that aspects of diverse cultures should be reflected in the English textbooks, thus enabling contemporary EFL learners to master the ability to use the English language efficiently in their intercultural interactions regardless of their socio-cultural background. The research findings succinctly reveal that the vast majority of state EFL teachers in Greece are fervent proponents of an intercultural approach in their teaching practices. However, they are not reliant on the prescribed textbooks under scrutiny for promoting the intercultural dimension in their educational methodology, since their cultural input is assessed as deficient and inadequate for dynamic intercultural instruction.
