The authors observed 24 children that are studying for the first time in the first grade of the elementary school. They were observed through the classical neurological examination, the evolutive neurological examination and through tests for evaluation of cortical functions. It is analyzed the school performance in report to the evolutive neurological performance and to the tests for cortical functions. Results obtained are compared and discussed. The authors conclude that the usage of these two evaluation instruments is able to discriminate the good from the bad school performance.
