A study analyzed the use of Basque and Spanish by 36 bilingual teenagers enrolled in a Basque school in Spain, based on results of a survey. The history and present situation of the Basque language are outlined, and the importance of the revival of the Basque language by those who learn it in school is highlighted. Complete technical data from the survey, which was given in English as part of the regular English class, is included. Analysis of the survey results encompasses the students' linguistic background and demographic data, linguistic competence and language dominance, domains of use of Euskera and Spanish, and their attitudes toward the Basque language and the Basque school. Influential variables discussed include the language used with friends, gender, linguistic competence in each language, dominant language, and the language used at home. Contains 13 references.
