I teach special education, grades k-6 for my district. I am a huge advocate of the Edmark reading program as SUPLEMENTAL instruction. I disagree that it is for students of a certain IQ, rather that it for students of a certain disability. It uses Direct Trial Training which is one of the few research-based techniques used successfully with children with autism. I use ReadingAtoZ.com for my direct instruction (even my youngest Kinder students on the spectrum) to teach language awareness and comprehension, and then have them work on Edmark 20 minutes to develop their sightword vocabulary. I see students make steady progress with both of these programs. I would also add that when I start a new child out on Edmark, I have to spend the first chunk of time (sometimes months), teaching the behavior of the computer, how to sit, how to click, how to repeat the words, etc. I focus only on this until it is mastered and then we focus on the words. It's an investment, but one well worth it. After a year in class, they can all work on Edmark (even level 2) independently.
