In both Brazilian and American educational and scientific contexts, the concept of a 'valid test' is central to academic rigor and credibility. In Brazil, ensuring test validity is particularly emphasized in public education (ENEM) and university entrance exams. In the USA, validity is a cornerstone of standardized testing and research methodology.
