The article underscores that the cartographic language used in social science textbooks for primary education in Spain is unsuitable and does not meet the demands of the official syllabus. Consequently, pupil literacy in geography with regard to regional geography is markedly ethnocentric. To demonstrate this, the cartographic content of textbooks is compared to the knowledge pupils have acquired on regional realities towards the end of this education stage. Specifically, certain aspects of mental maps of the Balearic Islands produced by year six primary pupils at twelve Majorcan schools are analysed. Based on this school cartography, a diagnostic exercise is performed on island pupils' literacy in geography in their last year of basic education. The use of spatial analysis tools enables us to conclude that there is low-level intersectionality between academic knowledge (insufficient) and ethnocentric knowledge (majority) - symbolic proof that the educational philosophy at most Spanish schools provides significantly poor learning.
