Problem
Billy is a 3rd grade child attending a primary school in a large country town. Billy is working approximately two years behind grade level in most areas. Billy's teachers believe his consistent non-attendance at school has had a significant impact on his literacy and numeracy development, this in turn impacts on his achievement in areas such as science and humanities. The school has discussed their concerns with regards to academic achievement and attendance with Billy's parents. He has been tested and shows an above average IQ and ability. Billy is on an IEP to address his attendance, literacy and numeracy issues.
What is Billy's diagnosis?
