This comprehensive informal reading inventory was based on the Harper and Row Basic Reading Program. It includes four major sections: a reading attitude inventory, a phonics inventory, a word recognition checklist, and an oral and silent reading inventory. The reading attitude measure is a list of 25 questions to be read silently and answered with yes or no or with a one-word response. Word recognition lists of 20 words each at levels preprimer through grade 6 are provided. Separate phonics inventories based on the skills sequence of the Harper and Row Reading Program are provided for preprimer through grade 3. The phonics inventory for grades 4 through 6 consists of 20 nonsense words. If the student reads these words aloud successfully, no further testing of phonics is suggested. Both an oral and a silent reading selection are included for grades 1 through 3. For each selection there are motivating questions and four to six comprehension questions, noted as either factual or inferential. One longer selection (about 200 words) for oral and/or silent reading is included for each of levels 4, 5, and 6. A chart of the number of errors which indicates the independent, instructional, and functional levels for each selection is provided. A summary survey form and references are included. (CM)
