There are still some outdated and unstandardized psychological tests in Brazil. This evidence points to the lack of researches about validity, reliability and normative data of psychological tests to be used with Brazilian people. Besides, there are few instruments to assess damaged cognitive functions caused by brain injuries. The purpose of this paper is to discuss the psychometric study of neuropsychological tests theoretically and to give the example of NEUPSILIN, developed to assess some cognitive functions briefly. More specifically, we will point the difficulties of developing psychometric methods to NEUPSILIN validation, as well as suggest solutions to these difficulties.
