The aim of this paper is to provide a critical overview of the issues and research conducted since the most recent state-of-the-art article published in the Annual Review of Applied Linguistics by David Singleton (2001). First, we summarize what research has said about the Critical Period Hypothesis (CPH) in cognitive science and neurobiology, then we review recent findings of age-related studies since 2000 focusing on what late beginners and adults can achieve, and how early and later beginners compare in bilingual programs. The second part of the paper explores language policy and classroom implications of the CPH for foreign language teaching. As English has become the lingua franca, early programs have mushroomed all over the world. However, besides overwhelming enthusiasm, more recently critical voices can also be heard. On the one hand, early exposure is often seen as a key to success and a solution to all problems in language education; on the other hand, it may be perceived as a threat to first language development and identity. Finally, we explore areas for further research.

The paper analyzes research published over the last five years. The first part looks into policy documents, types of programs, and surveys to identify (a) reasons why an early start to learning languages is seen as beneficial and under what conditions; (b) possible threats; and (c) the aims and expected outcomes that are predicted by various models. The second part discusses studies on learners, including what they do in classrooms, how they perform on tasks, how their languages interact, and how they develop in different skills. A separate section reviews individual differences in the affective, cognitive, and strategic domains, as well as the role of learners’ socioeconomic status and their learning difficulties. In the third part, we draw on classroom observation and interview studies to discuss teachers’ roles, proficiency and uses of languages, and beliefs and practices. In the fourth part, we focus on the assessment of young learners; more specifically, we review what the construct of assessment is, what various assessment frameworks include, what international and national examinations exist, and what assessment for learning involves. Finally, in the last section we review implications for further research.
