2 of mine have had trouble reading "fast enough" for there school, but it was handeled differently.

They had extra help at school each day, individually, and the homework didn't change as such, he was just sent a variety of readers instead of one, and we worked on what we could handle. They could pick how many, and which degree to do. We got sent the level below and above, so we could do an "easy" one if it was getting them down, or having an off night, or a "harder" one on a good night...

Homework is also only on Mon, Tue, Wed night, to be handed in on Thur. If you need more time, or are having trouble, you can keep it till Fri too...

So we would do one reader together, and the other was done in bed. They both picked up very well, without feeling too preasured, so a good result for us that way.
