convergent validity

Convergent validity is a concept that measures how well different tests or assessments that are supposed to evaluate the same ability actually do so. For example, if two different general knowledge quizzes yield similar scores for the same group of people, this suggests they are effectively measuring the same underlying knowledge. In simpler terms, if various ways of testing your general knowledge lead to similar results, it indicates that those tests are valid and accurately reflect what you know. This helps confirm that the tests are truly assessing general knowledge and not something else.
