The study of English has been introduced in the school curriculum of Young Learners in order to equip students with the language skills and competences required to become competent active citizens in the global marketplace. The production of teaching materials that scaffold/structure the language learning process is of prime importance in this regard. Coursebooks are perhaps the most used teaching tool in English as a foreign language classrooms in Portugal since they provide a basis for teaching and learning, and guide students throughout the learning process. Thus, this study seeks to determine whether Portuguese teachers prefer to adopt a locally produced English coursebook for young learners, written by local authors with a good knowledge and experience of the Portuguese educational system, or an international coursebook written for a global market. To accomplish this objective, a mixed methods research model with a parallel design was employed as the national and international coursebooks with the highest number of adoptions in 2015/2016 and 2016/2017 in Portugal were analysed. The results demonstrated that Portuguese primary teachers favoured English as a foreign language coursebooks produced locally rather than coursebooks produced internationally for a global market.
