The fourth edition of the Ekwall/Shanker Reading Inventory (ESRI) updates and expands this highly successful informal reading inventory. The new ESRI provides an expanded battery of 38 diagnostic tests in 11 different areas that enable the teacher-candidate, classroom teacher, special education teacher, or reading specialist to assess the full-range of students' reading abilities. The fourth edition provides for flexible assessment to match the needs of the individuals who will use it. The ESRI may be used as a quick screening device, for placement of students in groups or classes, for a brief assessment, or for comprehensive individual diagnosis. In this edition, specific directions guide the novice teacher or the experienced specialist in conducting the kinds of diagnosis appropriate for each setting. Based on the time-tested criteria of the informal reading inventory, the research-based, clinically verified ESRI is the most coherent and comprehensive reading assessment instrument ever developed. It provides clear, easy-to-follow instructions that tell the examiner exactly how to go about conducting and interpreting the diagnosis.The instructions for both administering the test and formulating a diagnosis have been carefully refined in this edition to make them even more user-friendly.
