He took the wisc-iv and his processing speed is really slow, the gifted lady said that can affect timed tests. But still, that wouldn't affect him actually knowing the facts, just how fast he can recall them and write them down right?
I think so, though I'm not an expert. My understanding of processing speed is that you have to take the information in, which means:
* Recognizing the information (e.g. 12- 5 = ?). This means recognizing the numbers and the signs, and then putting it all together to work out what you have to do.
* Then you have to get the answer
* After that, you have to send the new information back out again and get it on paper.
Some (many) people just don't do this super-quickly. That's okay and it doesn't mean they aren't as smart. They might not do well, say, on game shows where they have to shout out the answer before anyone else does or on timed tests. But they might do very well in situations where it's important to spend a lot of time thinking about something.
You might be able to talk to his teacher about the slow processing speed and ask what she can do to help.
