Psychometric properties

Psychometric properties refer to the characteristics that measure the quality and effectiveness of assessments, like tests or questionnaires. In general knowledge assessments, these properties include **reliability**, which ensures consistent results over time, and **validity**, which confirms that the test truly measures what it claims to measure. Other important aspects may include **norms**, which provide a benchmark for comparing scores, and **fairness**, ensuring the test is unbiased across different groups. Together, these properties help determine how well an assessment can evaluate someone's general knowledge accurately and fairly.
