The evaluation that they used with our son was called the Connor scale. It involves teachers, parents and others well aqainted with the child to fill out surveys about the child's bwehavior. The answers are then tabulated and charted. The chart does show designations between low/moderate/high ADHD levels and probability.
The biggest problem with it is that it is done independent of an IQ test or achievment testing. For the gifted population I'm not sure it is a reliable indicator. We had both testing done and with his IQ scores and the Connor scale they came back saying yes he shows alot of ADHD behaviors but stopped just short of saying he was ADHD. This was despite scores on the Connor Scale that put him almost across the board as a high level of ADHD. Instead he is officially listed as LD-undefined....not overly useful.
