Grade Calculator: Bell Curve & GPA Tool

A normal distribution, often depicted visually as a symmetrical bell-shaped graph, is sometimes used in educational settings to distribute student performance across a predetermined range. Software and online tools can facilitate this process by converting raw scores into scaled scores that conform to the bell curve, allowing for comparisons within a larger group. For example, if a class average on a test is 70% and the standard deviation is 10%, a score of 80% would be considered one standard deviation above the average.

Applying a normal distribution to academic assessment can offer insights into class performance as a whole, identify outliers, and potentially differentiate students based on a standardized scale. Historically, this approach has been utilized to normalize scores and maintain consistent grading standards across multiple sections or years. However, its use remains a subject of ongoing debate due to potential drawbacks, including penalizing high-achieving students in high-performing cohorts and conversely, potentially inflating grades in lower-performing groups.
