Grinity,

How would one go about finding a "top 20" tester? Do you have a list of testers around the country that you (or someone else) would recommend? What are the advantages that you see to using a "top 20" tester?

We did get DYS-level scores using a non-top-20 tester, but I didn't feel that the tester provided much insight into those scores, other than saying how much fun he has when he gets to see someone "run the test," as he put it. Would a tester who really sees a lot of DYS+ level kids generally provide more insight?
