The test was answered by 70 children from a Municipal Elementary School (2th to 4th grades), aged from 7 to 12 years old, 52,9% male. The test achieved internal consistency accurate data: .81 (inductive reasoning), 93 (short-term auditory memory) and .81 (short-term visual memory). According to the comparison between the results of this instrument and the data from students' teachers that were external and without criteria, it is possible to confirm that most of the cognitive measures presents coefficients correlated to external teachers ratings on areas such as motor skills, hyperactivity, writing, reading and math. 29 -.51.
