I'd like to know at what score you move to the 6+ on math? It's easy to find all over the internet when to move to the 2-5, but I can't find anything stating when to move to 6+ or what the max score is on the 2-5. DS got a 239 and will likely improve slightly over the summer. Will the 2-5 still be the right test for him in the fall? Is there any difference other than higher level questions being available? If that is the only difference, why have two separate tests? Since the school requires this testing 3x per year I want to at least make sure that the data is useful to us!
