Thank you St Pauli girl.

The tester actually compared achievement scores to grade level peers from current grade (Kindergarten) and the next grade (first grade):

Compared to Kindergarten:
Reading comprehension 144 99.8 %
Math Reasoning 141 99.7%
Math calculation skills 141 99.7%
Broad written language 143 99.8%
Written expression 132 98%

Compared to first graders:
Reading comprehension 125 95 %
Math Reasoning 120 91.7%
Math calculation skills 126 96%
Broad written language 128 97%
Written expression 118 89%

Has anybody approached the Gifted Development Center in Colorado for an educational consultation? I think I need more input or a second opinion from somebody who has seen lots of gifted kids (as compared to a regional tester). THis is such a big decision and I don't feel comfortable with this report's conlusion to not do a grade skip.
