The most comprehensive assessment tool of its kind, this diagnostic battery of tests is easy for busy K-12 teachers to administer and to interpret. The inventory measures both literacy and pre-literacy development and is simple and straight forward to administer. The test battery includes student interest inventories, graded word lists, tests for phonemic awareness and phonics, reader’s passages for determining reading and listening levels, measures for oral language, visual and auditory discrimination, and writing and arithmetic subtests. It also provides valid, reliable procedures for individual, in-depth assessment and is easily accessible for English Language Learners. The case studies within this text and ancillary videos accompanying this text equip professors with the means to show students how to administer the inventory and identify the struggling student.
