It was designed mainly as a measure of factor "g" of Spearman or general intelligence, composed by two abilities, named educational and reproductive.

The psychometric analysis shows that the item-test relation is up to norms (>0.20), so reliability was attained. Also the factor analysis of the items comes up whith one factor explainig the 76% of variance, so construct validity was obtained. Also the calification norms was obtained. The analysis of results points out the comparison with other studies, the difference among students from public and private schools, and the difference that female and male students showed.
