Accurate description of language use is central to English for academic purposes (EAP) practice. Thanks to the development of corpus tools, it has been possible to undertake systematic studies of language in academic contexts. This line of research aims to provide detailed and accurate characterization of academic communication and to ultimately inform EAP practice. Very few studies, however, have attempted to ascertain whether, and to what the extent, corpus-based findings have achieved such goals. The diverse nature of EAP, and the unique methodological challenges involved in compiling and using corpora, provide sufficient incentive for replication research in this area. The present article makes a case for replication of corpus-based studies in the field of EAP. It argues that replication research not only enhances the credibility of corpus linguistics for EAP pedagogy and research but also provides practical advice for EAP teachers and materials designers. It then looks at how two key corpus-based studies on the topic, Cortes (2013) and Biber and Gray (2010), can be replicated with respect to replication approaches described in Porte (2012).
