Abstract
About test validity. More than two years have passed since the publication of the last standards for educational and psychological testing (AERA, APA y NCME, 1999). This publication is the best and foremost reference for test evaluation, construction and use. The most important contribution to the previous version published in 1985 is the emphasis in guaranteeing proper use of the tests, thus bestowing upon the user new responsibilities in the process. As a result of this, new sources of evidence for validity analysis such as differential item functioning and consequential validity have prouted strongly. The objective of this study is to provide a general overview on "validity" based on the latest standards, which is the most relevant feature for both test development and test evaluation.
