The work has a dual purpose (1) to know satisfaction in BPE-CLIL (Bilingual Physical Education in Content and Language Integrated Learning) and (2) to know if students’ satisfaction can be conditioned by gender and/or age. A non-linguistic discipline as Bilingual Physical Education assumes that it is necessary to take into account objectives of two types (contents and linguistic) and students’ satisfaction has a fundamental role. A quantitative analysis is done using a Sport Satisfaction Instrument (SSI) to collect data from Primary Education learners under a CLIL methodology. The questionnaire has been validated for bilingual Physical Education in Spain and it was applied to 350 students (5th and 6th grades of Primary Education) belonging to bilingual schools in the autonomous community of Castilla-La Mancha. It is a strong and reliable instrument since the internal consistency has indicated a high Cronbach's alpha regarding fun and boredom. Satisfaction indexes have been different regarding age and not regarding gender in Bilingual Physical Education in Primary Education.
