Those scores are definitely high, but to determine if you should get further testing it would be important to think about whether your DS is happy with school as it is right now, what the level is at which your DS's classmates are performing, whether there is anything that concerns you about your DS's behavior or emotional state, etc. What kinds of things are you seeing at home and at school? $1000 is a lot to spend, so if everything is a-ok right now then it would be fine to wait, but if something is not right then ability and achievement testing could help you get a clearer picture of your DS and might help you advocate for a change, if necessary.
