"Meeting a key need for early childhood professionals, this book presents clear guidelines for authentic developmental assessment of children from infancy to age 6. Unlike tabletop testing procedures - which do little to guide instruction or track progress toward individualized goals - authentic assessment captures data about children's everyday skills displayed in everyday routines. Providing a valid basis for intervention planning and progress monitoring, the practices and principles outlined in this volume are supported by current professional standards and a growing evidence base." "This state-of-the-science guidebook will enhance the knowledge and skills of school and clinical psychologists, special educators, and others involved in assessing young children. Graduate students in these fields will find it a well-organized, accessible, and highly informative text."--BOOK JACKET.
