Thanks for the response Grinity

She takes a long time to do things. For example, she does not finish the work assigned in class in the time allotted, some of it I think is because she tends to be a little perfectionist, but she gets frustrated when she's lagging behind her class, and then she needs to catch up at home. This doesn't happen always, but enough times that it makes me wonder.
Also, her teacher took assessments at the beginning of the year to figure out where all the kids where in math and reading (these were computer tests). She took 3 times as long as the "average" time to finish it, it was so long the teacher had to split it for her into sessions.
She has been screened for gifted, but she missed it by a few points, even though one of the teachers tells me she shows characteristics of gifted kids.
She's always been like this, though... always taking longer than other kids to finish up, even in her pre-k class.
We're lucky that she goes to a gifted school and the teachers work with us (she's also doing advanced work), but I want to find out if there's an LD so we can help now and not wait until she hits middle school and is overwhelmed.
Thanks!
