This book is a practical guide for assessing the effectiveness of classroom instruction. The new title, Assessment of Student Achievement, Sixth Edition, reflects a greater emphasis on types of achievement assessments other than classroom testing. It stresses the importance of using both classroom tests and performance assessments for a comprehensive assessment of all intended learning outcomes. In addition, a chapter is devoted to each of the following topics: how to prepare and use classroom tests and performance assessments and how to assign grades and interpret standardized test scores to students and parents. The material is presented in a simple, direct, and understandable manner.
