So many of you were helpful when I posted the original message, I am back for an update. We did have our son privately tested. The psychologist used the Woodcock Johnson III tests for ability and achievement and Developmental Test of Visual Motor Integration (VMI). The nutshell results were
"General Intellectual Ability" = 132 (98th percentile)
Broad Range Reading = 94 percentile
Broad Range Math = 98 percentile
Broad Range Written Language = 98 percentile

Here is the curious part - almost all of the subtests were well above the 90th percentile except those labeled "fluency" which were lower. Those were timed. He scored in the 76 percentile on writing samples and 28th percentile on the Processing Speed test.

We have had him identified with the school district and the teacher is working on higher level instruction in reading and math to some extent.

Any ideas as to where we go next to figure out what is going on with the processing speed or should I just let it go? My fear is that we will run into more teachers that confuse speed with ability.
Thanks!
