I'm really confused as to the meaning of his score discrepancy and how I should proceed.

Is it a testing flux � i.e. could he have been so distracted/bored (he is quite hyperactive) that he just didn�t want to answer? (or knowing him, that he purposely gave �silly� answers to make things more fun)? How likely is this scenario? Is it �worth� requesting a reassessment?

Does he have a learning disability? Is this discrepancy a reasonably indicator of one?
