This paper reports on the outcomes of a study on stakeholder perspectives on catering for diversity in Content and Language Integrated Learning (CLIL) in Spain. It is part of the large-scale SWOT analysis conducted in Europe within the project 'CLIL for All: Attention to Diversity in Bilingual Education (ADiBE)'. The research has involved the administration of two sets of questionnaires to 926 informants (742 students and 184 teachers) within 15 secondary schools of four provinces. After framing the topic against the backdrop of the project, the paper will expound on the objectives, methodology, variables, and procedure employed in this particular study in Spain. The bulk of the article will outline its main findings in relation to the five main fields of interest which have been canvassed: linguistic aspects, methodology and types of groupings, materials and resources, assessment, and teacher coordination and development. Across-group comparisons will be carried out to determine whether there are statistically significant differences between both cohorts. A diagnosis of where we currently stand in Spain in the process of catering for diversity in CLIL will be provided in light of these results and a future CLIL agenda will be carved out on the basis of these findings.
