A great deal has been learned about factors that influence achievement in basic areas of functioning such as reading, writing and arithmetic. This knowledge is tempered with the realization that assessment of achievement, as well as the factors underlying achievement, is complex. But teachers of children, adolescents, and adults have instructional decisions to make, and those decisions are best made with diagnostic data.The Bader Reading and Language Inventoryis a comprehensive diagnostic battery that encompasses vital areas of evaluation, is based on years of clinical research and practice, and is efficient to administer and interpret. The instruments within this inventory are specifically designed to assist teachers and specialists to discover conditions that inhibit learning and determine which intervention strategies can be used to improve learning.The Bader Inventoryhas been the inventory of choice for many who work with struggling readers, English Language Learners, and adult learners. This new edition has been carefully reviewed and revised to ensure it continues to meet those specific diagnostic needs. Included in this edition are additional resources to benefit practitioners. NEW! A DVD now accompanies this inventory to allow first-time users to practice how to administer the inventory and its various tests and sub-tests. Readers observe tests being administered in a real setting and practice completing an Examiner's Copy data sheet at the same time as the DVD Examiner. They can then compare their completed data to the DVD Examiner's data sheet and determine if they understand how to use the inventory. Observation examples are provided for various grade levels. NEW! The Readers'Passages are now in the back of the text. Classroom teachers and clinicians can now create their own Readers'Passages booklet to assess children or adults. NEW! Reliability and validity statistics, collected over years of use of the Bader Reading and Language Inventory in clinic settings, are now included in Part Four of the text. The Bader passages and comprehension questions have been modified over time to ensure greater text reliability and validity and avoid test bias, especially for English learners.Lois A.
