Nicaragua published its first series of textbooks for the teaching of English in public secondary schools in 2016. This article reports on an investigation of the first three textbooks belonging to this series. The aim was to see how the textbooks follow up the Nicaraguan national curriculum, which emphasizes the need for learners to develop communication skills. We discuss the approaches with reference to principles of communicative language teaching and Nation's four strands for a well-balanced language course. We identify significant discrepancies between the three books and, thus, a lack of progression in the course. The investigation is also an example of the affordances of our analytical tool for textbook analysis.
