This book examines the effect of prior attendance of preschool on literacy competencies of school going children as they progress to later grades. Relying on the human capital (HCT) and social justice theories, the book provides vital information for researchers in reading and demonstrates whether investment in quality preschool experiences is a worthwhile venture. Important policy considerations are also elucidated. Moreover, evaluation experts planning for baseline, mid-term or end-line evaluations in literacy will find this an essential resource.
