I agree with others that you are likely seeing percentiles among NUMATS participants versus the original percentiles against all 8th grade participants. Both percentiles offer good information, IMHO.
I'm curious if the NUMATS toolbox provides a chart of all scores and percentiles or just your child's percentiles? Duke TIP hasn't posted any of the participant percentiles yet so all I have is how my child compared to 8th graders. We have a conference at school tomorrow and if anyone could tell me how he did in the NUMATS pool, I'd greatly appreciate it. But if they are only providing you with your student's percentiles versus a chart that wouldn't be possible. I'd be happy to post scores if someone thought they could help.
