This study aimed to obtain the first evidence of validity to the Test Identification Signs of Dyslexia (TISD). We investigated two groups of children, one without learning difficulties (n=9) and other with learning difficulties (n=11); the second group was selected due to possible risk of learning disabilities. Two instruments were used for data collection Academic Performance Test (TDE) and TISD. The results showed differences between groups in the scores of the subtests of reading, writing, calculation, phonological awareness, working memory and total, with better performance in the group without learning difficulties. Significant and negatives correlations between TDE and TISD was found. It was found that the TISD proved capable of differentiating the groups, as well as correlations obtained with another instrument that assessed similar constructs, the aim of this study was reached.
