I was required to read this for an administrator's retreat. I must admit that I was unhappy about this... it seemed like such an academic book. Fortunately, it was a better read than I thought it would be. Points are all clearly made and provide enough information to replicate. Unfortunately, the author writes in a very repetitive style... which becomes tedious at times.
I do see it as a book that could be best used as a resource when districts are revising report cards...Unfortunately, we did this last year (before we had the Gutsky book!)
