Following the style of the 1958 original, this third edition of the Neale Analysis of Reading Ability is both a standardized attainment test and a diagnostic test for readers of all ages and thus can be used to assess reading progress objectively as well as to obtain structured diagnostic observations of an individual's reading behavior. It contains information concerning the development, description, administration, and scoring of the test, tables of norms, guidance for interpreting the test data, and research studies illustrating how the Neale Analysis has been used. Main changes in the third edition include revised and enhanced format and design to enhance legibility; new parallel passages; redesigned individual records; a new chapter presenting case studies illustrating the application of results; and word lists for "quick" assessment of accuracy or word recognition skills. Chapters in the book are: (1) Introduction; (2) Introducing the 3rd Edition of the Neale Analysis of Reading Ability; (3) Guidelines for Administering the Neale Analysis; (4) Scoring the Neale Analysis; (5) Interpreting and Using Standardised Scores; (6) The Diagnostic Tutor; (7) Supplementary Diagnostic Tests; (8) Beyond Testing: Case Studies using the Neale; and (9) Development of the 3rd Edition of the Neale. Contains 134 references, 17 figures and 14 tables of data; appendixes contain an 116-item glossary, a list of participating schools, and 4 separate individual scoring sheets. (RS)
