This study explores the affordances of English for Specific Purposes (ESP) in teacher education, in light of recent policy changes expanding English instruction in early childhood education across the Region of Madrid. Specifically, the language needs of a group of 25 preprimary student teachers at Universidad Autónoma de Madrid were analysed through a multilevel needs analysis based on mixed data-collection tools (focus group discussion and survey), with the aim of informing the design of an ESP course tailored to future preprimary English teachers. The findings offer a tentative profile of their linguistic competence and a replicable model for needs analysis, which may guide ESP course development in similar educational contexts.
