This article documents the findings of a study concerning the perspectives on Content and Language Integrated Learning (CLIL) in the monolingual context of Jaén. The research has involved the design, validation and administration of two sets of questionnaires to 745 informants (692 students and 53 teachers) within eight secondary schools with a view to identifying student and teacher attitudes towards Andalusian CLIL in the province of Jaén. Perceptions are outlined in terms of students' use, competence and development of English in class; methodology; materials and resources and ICT; evaluation; teachers' use, competence and development of English in class; teacher training; mobility; improvement and motivation towards English; and coordination and organisation. The article begins with an overview of prior research, subsequently reports on the research design of the study and concludes with the presentation of the main findings of the investigation. An extensive evaluation of stakeholder perspectives on CLIL in the province of Jaén reveals a predominantly positive outlook on behalf of the student and teacher cohorts with regard to the implementation of a bilingual programme within the Andalusian region of Spain.
