Are there any teachers or MNs who can tell me the difference between the book band colour and the reading stages? My ds (Yr 1) came home today with one book that looks like it's the same stage as before and another that spans three stages, one below and one above, they both have different colour bands. There was a note in his diary saying they were moving him up to this next colour band as he was doing so well. Not at all worried as he seems to be doing well but is this 1 step forward and 2 back or just conflicting systems ?
