Hi saker yes it's the distance program specifically for children with autism. It;s also called "Light on Literacy" although she also has a phonics plus 5 scheme for NT kids (think that's what its called) and has written an excellent book (imo) about teaching reading to NT strugglers.
It takes us about 45-55 minutes a day (but we're still on pre-reading). It would be shorter if ds1 was better behaved! He finds the work fine (he finds receptive language hard and is very ropey at handwriting, but the rest OK), but he finds maintaining his behaviour difficult. Remember he is very severely autistic though, she wants good behaviour but not unachievable.
I'm finding it excellent, right at his level, quite hard to do (but that's just working with ds1 at the moment- whatever we were doing - it's the getting him sitting and concentrating that is hard, nothing to do with the program itself).
As for does it work? Well 2 days ago ds1 typed out of the blue a whole load of words. I mean lots & lots of words. A total surprise. I personally suspect its because she teaches about spaces etc. I'm looking forward to reaching the reading activities and seeing how ds1 progresses. She (imo) knows what she is doing.
I'd talk to her - she assesses whether your child is right for the program - you have to send video for her to see- and tbh if ds1 can do it I'm sure your son would fly through. She may say that he doesn't need it and would be fine with her standard program. I think Light on Literacy has been specifically designed for children who are non-verbal, although don't quote me on that.
She knows all about reading though, so I'd contact her anyway.
