This reader-friendly text takes a holistic approach to what future teachers need to know in order to assess children from birth through age 8, based on the recommendations of professional organizations—NAEYC, AERA, DEC, and ICDL Clinical Practice Guidelines. To prepare students for what the author sees as one of an early childhood educator's most important roles, she thoroughly addresses theory, provides illustrations of appropriate practice, and discusses current trends, including such “hot topics” as high-stakes testing, resisting testing, link to standards-based teaching/assessment, and coping with legislative demands, including HRI Leave No Child Behind. In addition, she emphasizes the importance of including children with disabilities and collaborating successfully with parents.
