"This is a must-have book for both in-service and preservice teachers. It addresses the continuum of observing and assessing children from birth to grade 3, including approaches for children who are dual language learners. With engaging, easy-to-read articles written by various experts in the field, this text is ideal for college courses and makes the challenging task of formative and summative assessment not only understandable but doable." —Holly Seplocha, Professor of Elementary and Early Childhood Education, William Paterson University
