This study aimed to verify the effects of developmental variables as age, school grade and gender in the performance of the Test for Identification of Signs of Dyslexia (TISD). In particular from the analysis of the first two, it was also sought to verify validity evidence based on external variables. Participants were 515 children, randomly selected, ages between six and 13 years old (Mean = 8.46; SD = 1.52), and 52% of males. Through the Univariate Analysis of Variance, only effects of age and school grade were found. It was observed that TISD was able to differentiate groups of six, seven, and eight years old and the school grade of the 1^st to 4^th grade of elementary school. From these results, it was possible to add positive validity evidence to the instrument, in order to motivate the conduction of other research studies of its psychometric qualities.

Keywords : dyslexia; learning disorders; psychometry; validity; neuropsychology.
