The goal of this study was elaborate a set of tests, "Multidimensional Battery for Children's Intelligence" or "BMI", according to the abilities included in the Cattell-Horn-Carroll's Model. Among these abilities are the ability of crystallized intelligence, fluid intelligence, processing speed, short-term memory, long-term storage and retrieval and quantitative knowledge. The BMI was composed by nine tests, presented to two samples of participants. The first sample comprised 240 children whose age ranged from seven to 12 years old. Constituted for the testing of new items, the second sample comprised another 206 children. The results demonstrated that the age had a high influence on the tests performance. Were found high reliability coefficients for the tests General Information, Induction, Mathematics Achievment, General Vocabulary and Picture Vocabulary. The analyses of their difficulty levels and their discriminitative power led to the choice of the best set of questions to integrate the final configuration of the Battery.
