Test Score Scaling

Test score scaling is the process of adjusting scores from different tests to create a common value system, allowing fair comparisons. For example, if two different general knowledge quizzes have varying difficulty levels, scaling ensures that a score of 80% on one quiz is comparable to a score of 70% on another. This process often involves statistical methods that account for differences in test content and difficulty, ensuring that all scores reflect a similar level of knowledge. Ultimately, scaling promotes fairness and accuracy in evaluating performance across diverse assessments.
