Psychometric Theory

Psychometric Theory is a field of study focused on measuring mental capacities and processes, often through tests and assessments. In the context of general knowledge, it examines how well a test can accurately assess what a person knows about various topics. This involves creating reliable and valid measures, ensuring that the tests consistently produce the same results and truly reflect a person's knowledge and understanding. Essentially, it provides a scientific framework for evaluating and interpreting people's knowledge through structured assessments.
