Performance-Based Assessment in CLIL

Assessment is probably one of the most controversial aspects of Content and Language Integrated Learning (CLIL) mainly due to the balance between content and language, the role of language in the assessment process, and the lack of guidelines and appropriate assessment tools for the specific contexts. This chapter highlights performance-based assessment in CLIL as a powerful strategy to assess students' knowledge effectively by means of measuring competences or skills. The chapter starts with an overview on the impact of assessment in education, and conditions for performance-based assessment. After analyzing the necessary competences to express content knowledge in CLIL subjects, attention will focus on the best assessment tools in line with formative assessment, and the need to scaffold tasks and exam questions.
