Just my experience here -

2012 DS started K early at four
2013 Repeated K
2014 Progressed to first
2015 Progressed to second
2015 Accelerated to third after two months in second

I highly recommend trying Toe by Toe. My son was evaluated by the Eides (2e specialists) in 2013. Doing Toe by Toe at home was one of their recommendations for him and at $40 for the book and 20 minutes a day, it was the least expensive. It is available on Amazon. It certainly won't harm anything to work with her using that book even if she doesn't have dyslexia.
