This article explores the idea of portfolios as a way to collect evidence of pupils' learning and achievement in their language learning in the primary school. The emphasis is on portfolio work as an active and reflective process to underpin and support learning and to show evidence of achievement and progression. Pupil choice and reflexivity are essential in the process. The process can encourage learners to draw on their learning experiences across the curriculum. Whilst a means of providing evidence of learning, and for showcasing work pupils are proud of, portfolios are seen as central to and embedded in the day-to-day learning and underpinned by the principles of formative assessment. Designed to be used with other modes of assessment including the European Languages Portfolio, portfolios are in essence flexible, inclusive and a dynamic record of learning, achievement and potential for every learner. In this article, the use of portfolios from an early age as a means to promote development and learning and a way of assessing learning are inextricably linked. Teachers working to develop portfolio work, and some of their pupils, add their voices to the discussion of portfolio development towards an enhanced dialogic assessment culture.
