Your child's scores look much like my dd's in 5th grade..this year she was at a 24 composite with two perfect subscores in 6th grade. I think for my dd it was experience with this form of testing. This year she knew exactly what to expect. My dd likes to take the test "cold", she does no prep, not even the booklet that comes with the testing registration. My thought is to listem to what your child is telling you...not what the school says.
