There are several resources to facilitate the interpretation of psychometric tests. The main difficulty they present is knowing which standardized scores each of them uses, what their mean and standard deviation are, in order to transform them into the score system that is most convenient or familiar to us (z, for example).
On the website of the General Council of Psychology of Spain there is a list of tests published and validated in Spain, with a summary that includes the type of standardized score used by each one, the ages for which its use has been standardized, and other technical information on its use.
On the website of TEA Ediciones, one of the publishers with the most tests commercialized in Spain, there is also information regarding each of the tests.
