Based on the time-tested criteria of the informal reading inventory, the research-based, clinically verified Ekwall/Shanker Reading Inventory 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.
