Literacy Education and Second Language Learning for Adults (LESLLA) is an international forum of researchers who share an interest in research on the development of second language skills by adult immigrants with little or no schooling prior to entering the country of entry. The goal of the LESLLA is to share empirical research and information to help inform and guide further research on second language acquisition for the low-educated adult population. This research in turn will provide guidance to education policy development in all those countries in which immigrants settle and most need educational support.

LESLLA intends to bring together linguists, psycho-linguists, psychologists and educational scientists to establish a multi-country and multi-target-language research group to study effective methods of language acquisition and literacy. No other group exists that meets regularly to consider interdisciplinary research on adult immigrants learning to speak and write a language other than their native language.

Regarding the second language and literacy development of beginning adult second language learners with little or no home language schooling/inadequate schooling or literacy, the Association promotes on worldwide, multidisciplinary basis, the sharing of: research findings; effective pedagogical practices; information on policy.

LESLLA was established at the first workshop held at the University of Tilburg in the Netherlands on 25-27 August 2005. Since then, LESLLA holds an annual symposium, alternating between Europe and North America.
