I have a very similar situation going on with my kindergartener. He is getting a private assessment in a few weeks for giftedness, LD's, etc.

There is a lot of information about dyslexia at www.dyslexicadvantage.com and you might be able to get a recommendation for a competent specialist in your area. There is also a forum there similar to this one. You might want to post your question there too.

I would talk to the teacher about the homework. If you think your child is having to spend too much time on school work at home you need to let the teacher know. She might be sending something home that she thinks will take fifteen minutes that is taking your child forty five minutes.
