The information technology is an education elementary tool. An instrument able to analyze teachers performance using this technology as an educational tool is very important. This research purpose was to evaluate the psychometrics characteristics of the Educational Informatics Performance Scale through an online pilot study. 82 elementary teachers from public and private schools were the subjects of this study. Educational Informatics Performance Scale, which was answered online, was composed by 51 items with 4 answer choices each one in order to define every teacher's profile. The results has presented a good internal consistency (αCronbach =0,9678) and a 0,3792 average items correlation. The instrument internal precision has identified the items homogeneity, and it was verified by the split-half method. The factorial analysis has suggested some items rearranges according to the scale definitions. The psychometrics qualities added to the results of factorial analysis has revealed the Educational Informatics Performance Scale effectiveness validity.
