<p>I’m surprised the author of the article minimized the significance of a 20 point fudge because the test has a “total of 800 points”. If it were a single student’s score it would be insignificant, but when the number represents the mean of thousands of students it would reflect a much higher overall increase. How many students would need to score higher to move the mean 20 points? One of the articles on the topic mentioned that no individual scores were altered, so are the scores reported just jotted down by one person with no oversight?</p>
