This paper is a summary paper of the Thematic Working Group (TWG) on Adult Mathematics Education (AME). The theme AME made its first appearance on CERME11 and in this paper we provide an overview of the growing and blossoming field of AME and the results of the working group. The main themes associated with AME are: the definition, scope, and assessment of numeracy, the role of language and dialogue, the role of affect, including motivation, and the role of societal power structures, including subthemes like equity, inclusion, vulnerable learners, agency and self-efficacy. We conclude with the opportunities and challenges for this theme from both scientific and societal perspective.
