Based on three studies of adult literacy in Iowa, this book identifies policy issues raised by research on adult literacy and recommends solutions. It also examines adult literacy education from the perspective of the learners themselves in order to inform improved practice. The book addresses six basic questions that are the topics of the first six chapters: What is adult literacy and adult literacy education? What factors define and describe the adult literacy population? What motivates adult literacy students to attend? Why do many of those eligible for adult literacy education elect not to participate? What are the outcomes and impact of adult literacy education, and What are the implications of the analysis for adult literacy and policy? A seventh chapter contains recommendations for practice and for research and a conclusion. The book is indexed by author and by subject. (Contains 155 references.) (KC)
