We have it in my district. I have seen a tremendous improvement in auditory discrimination tasks, prereading and early reading skills. I don't use every "sub-program" on the CD, but I do use most of them. It is very interactive so is especially helpful for our students that have a difficult time attending. I have found it very easy to use and navigate through, too. I have found some CD's that are "educational" tend to be presented in a regular to slightly fast rate of speech. Not this one...it's even and clear and the perfect tempo for my kids that process a little slower.
