Try not to worry too much about it! My guess is she did great

FWIW, our ds has been tested multiple times, and he always tests consistently at around the same level. The first time he had an IQ test it was spread over two sessions, each seemed like they were around 90 minutes. The second time he had an IQ test, I wasn't sure that I wanted to share the results from his first evaluation, so I took him in for testing and then sat in the waiting room with the envelope containing the first testing report contemplating whether or not I should give it to the neurospych who was testing him that day. After about 30 minutes, they both came out for a water break, so I decided to just give her the report so I could go run an errand and forget about it all.... (ds was supposed to be at her office all day).... I gave her the report, told her the #s... and she replied "Yep, that's right in range with what he had when I tested him this morning!"... sooooo... go figure!
Then... he had his third test a few years later through school, but we were not going to be told when he would be tested, which was frustrating for me, because I wanted to try to be sure he got a good night's sleep and had a good breakfast before testing. Instead, what happened was I took him ice skating on an early school release day, he took a hard fall, fell on his head, sliced his mouth open when he bit it during the fall, had a headache that was still raging the next morning but went to school anyway because it was during the one part of the school year where kids got to spend the full week studying a special elective class (one topic) of their choice.... and wouldn't you know it, that's when they pulled him out for testing. Not only did he have a mega-headache still... he was fuming mad because he had to miss the class he was so excited about!
He still had the same IQ profile.
Once again, go figure!
I hope your dd gets into the program!
