Like Dottie, I'd also try to have your 4th grader tested on the 6+ test. The main reason is that the growth information will be the most useful for you over the next few years. I'd be more comfortable comparing growth on the same test instead of one where the ceiling issue could be coming into play. I saw it with DD8 when she went from P-MAP to the 2-5 this year and I had to recalibrate.
I also think that PDF you posted earlier has goal information.
