Those scores are excellent....our son has taken the ERB CTP 4 three time, first as a 4th and then 5th grade , and now as a 6th grader....still waiting on the results for this year. His scores in 4th grade were very similar.
IMHO, you definitely should consider some above grade level testing for your daughter. You will probably be absolutely amazed...I know we were. I believe both Duke TIP and CTD/NUMATS are coming up with a new test to replace the ACT Explore. It will be interesting to hear what the school says...my guess is they may not have seen scores like these before...good luck!
