This book provides a detailed account of how to administer, score, interpret and write up a WISC report in a user friendly way. I have found it very useful as it gives more information than the WISC interpretive manual does, especially if an index is not interpretable. The CD is beneficial as a way to check that you have scored the assessment correctly, however I found that the appendix that are provided on the CD might have been more useful in the book as I am not always near a computer when scoring/interpreting. Have ended up printing them out and storing them in the book. Other than this a highly recommended book!
