Comisión de Test: Veinticinco años velando por la calidad de los test.

The objective of this paper is to present the activities and projects carried out by the Spanish Test Commission, established by the Spanish Psychological Association to improve the quality and use of tests. The most relevant projects of the commission during its twenty-five years of existence are reviewed, describing the work carried out: a) to understand the opinions and attitudes of psychologists towards the tests, b) to evaluate the quality of the tests published in Spain, and c) to develop standards, guidelines, and ethical and deontological codes to improve testing practices. The commission's other activities of a formative nature are also highlighted, as well as its relationships with other international organizations with similar purposes. Finally, several reflections on the future challenges of the Test Commission are shared, emphasizing the key role new technologies will have in psychological assessment. [ABSTRACT FROM AUTHOR]
