A tool designed to adjust test scores often employs a mathematical formula to raise overall averages. This process can take various forms, from adding points to each score to scaling results based on a pre-determined distribution. For example, a simple method might involve adding a fixed number of points to every student’s raw score. More complex approaches might involve fitting the scores to a normal distribution or using a logarithmic curve.
Score adjustment offers several potential advantages. It can mitigate the impact of overly difficult exams, ensuring that student grades reflect their understanding of the material rather than the test’s difficulty. Additionally, it can create a more consistent grading standard across different classes and instructors. Historically, adjusting assessment results has been used to address variations in test difficulty and maintain expected grade distributions within academic institutions.
