I think it's extremely important as an assessment professional to maintain a level of humility with regard to any client, but especially for low-incidence learners like twice-exceptional students. Even for those of us who may have encountered a few more of them than others. There's an old principle in assessment along these lines: interpret the test in the context of the child, not the child through the lens of the test.
