<div>A classical criterion for diagnosing ID is an IQ
below 70 associated with severe adaptive problems and onset in developmental
age, while for SLD it is a discrepancy between a high FSIQ (or an average
intelligence) and poor academic performance (American
Psychiatric Association, 2000). In Italy, for example, a diagnosis of ID
currently requires a FSIQ below 70, whereas a diagnosis of SLD is typically
used for cases with a FSIQ above 85 associated with a clear discrepancy between
this high FSIQ and a low achievement at school (Istituto
superiore di sanita`, 2011). This approach has recently been questioned
for a number of reasons. <br></div>
