My son was tested at 5 years 3 months (WJ-III). He is in K in Montessori but it's his first year there. I think there wouldn't be too much difference between him and my son. I must add though that my son was exposed to regular workbooks at home, not that he would have got too close to them though
I don't think you need to do anything special. One note though. The psychologist didn't give him one of the writing subtests (he took 2 out of 3) so he doesn't have writing cluster score nor does he have the total achievement score. His broad math score is very high and we hope he will get accepted to DYS based on this score. His Academic skills score and Brief Achievement are really high, I just wish we had the whole picture so to speak.
We asked her about it later on and were told that she gave him all the tests typically given to a 5 year old. You may want to talk to the psychologist ahead of the time and request all the scores. Good luck with the test.
BTW Do you intend to keep him in Montessori for Kindergarten?
