This article discusses the state of the art in the field of "adult ESL" in the US. It identifies the size, characteristics, and settings of adult education and discusses relevant professional standards, assessment procedures, and teacher preparation. Three approaches to noncredit adult ESL education will be presented (Functional Literacy, Critical Literacy, and New Literacy Studies), each of which has relevance to current status and funding of adult ESL within the Department of Education. A broader view of curriculum design and expansion of technological applications are recommended to address the growing needs of immigrants from Latin America and around the world.
