Raven’s Standard Progressive Matrice. Contribution to Italian standardization for subjects between ages 6 and 18.

This paper presents a standardization study of Raven’s Standard Progressive Matrices on an Italian sample of 5438 youth aged 6 to 18 years. Although this instrument is very well-known and is dated, even now it is useful for a rapid assessment of cognitive abilities, as confirmed in international literature through a comparison of results from other tests which measure the same construct. This calibration study confirms the relationship with age, as well as the influence on the youth’s performance of social variables, such as parents’ schooling level used as an indicator of the family’s social-economic level. The raw scores obtained by the sample were converted in standardized points for age (IQ with M = 100 and SD = 15). Reliability and standard measurement error were calculated. These parameters are included in the report by Giunti Testing; their purpose is to supply a correct interpretation of the scores obtained
