This volume provides a detailed account of the practical use of Assessment for Learning (AfL) in primary language classrooms. It gives an in-depth account of the ways in which eight experienced primary language teachers incorporated this type of assessment into their practice and discusses the possible impact of AfL on primary language learning. Key themes discussed in the volume include the relationship between AfL and language learning in childhood, which assessment methods are appropriate for primary-aged language learners, which methods support learner agency and engagement in the learning processes, and possible paths for future action, with a focus on implementation and researching AfL in primary language contexts. The findings of this book are relevant to global contexts and it will be of interest to postgraduate students and researchers in the fields of language education, language assessment and teacher education, as well as to primary and language teachers and school leaders.
