This battery of tests - the "Instrument II" - was selected in order to increase the sensitivity of the psychometric evaluations for children from 5 to 6 years old and designed to be used as a complementary resource for the former mechanisms - the "IADPE" and the "Scale" both used on the CEAPE program. The present article studies the main statistical characteristics of the "Instrument II". It was found to increase the sensitivity of the psychometric evaluation of preschool children of the age quoted. A positive and significant correlation among the three methods mentioned was also obtained. On the basis of these results one can suggest that the "Instrument II" can be used as a complementary evaluation test for estimating the socio-psychological progress in preschool children of 5 and 6 years old belonging to low socio-economic classes.
