Deviation scores are used to measure the difference between a student’s actual score on an assessment and their expected score based on the average performance of their peers. It is an important measure for understanding how students are progressing in their studies and for determining the effectiveness of a particular educational program.

Deviation scores are calculated by subtracting the average score for a student’s peers from their own score. For example, if the average score for a given assessment among a student’s peers is 95 and the student’s own score is 90, then the deviation score would be -5. This indicates that the student has performed below the average of their peers by 5 points.

Deviation scores can be used in a variety of ways. For instance, they can be used to compare a student’s performance to their peers and identify areas where they are excelling or falling behind. Additionally, deviation scores can be used to identify the effectiveness of particular educational programs and to inform decisions on how best to allocate resources.

Finally, deviation scores can be useful in measuring the overall performance of a school or district. By analyzing the deviation scores of students across different grades and subject areas, administrators can identify areas where the school is excelling or where there is room for improvement.

In summary, deviation scores are a powerful tool for assessing the performance of students and for measuring the effectiveness of educational programs. They can provide important insights into how students are progressing in their academic pursuits, as well as help inform decisions related to how best to allocate resources.
