What are value-added scores and why use them?
Value-added (VA) scores express the extent to which a group of students exceeds expectations in terms of the proportion of them who are awarded a 1st or a 2:1. Expectations are determined through reference to the proportion of higher degree awards (i.e. 1st or 2:1) when awarded to students throughout the sector who share a similar profile.
Kingston University adapted the method of calculating VA scores, originally created for The Guardian newspaper league tables by Kingston University’s Head of Planning, so that subject of study is considered in addition to entry qualifications when setting expectations for each student. VA scores above 1.0 are good – they indicate that the students concerned have exceeded expectations. Scores under 1.0 show that the distribution of awards to the group concerned contained fewer 1st and 2:1s than would be expected given the profile of the students and how similar students throughout the sector fared.
The major advantage of the VA-score approach is that it enables Kingston University to create a story for each student by taking account of prior entry qualifications and subject of study when assessing their degree attainment. By using data for all graduates across higher education in the last five years, they can arrive at the probability that a given student will achieve a 1st or 2:1 degree. If the cohort achieves this percentage then the VA score is 1.0, for attainment above or below the expectation, the VA score will be proportionately greater or less than 1.0.

Interested in adopting a value added metric at your university?
Dissemination of the VA data and Kingston University's overall approach has been carried out through a series of meetings with academic teams, creating a safe environment in which to discuss the attainment gap and facilitating conversations around influencing factors and the support available.
Value-added data at this level has proved a very powerful means of engaging staff in discussion around the attainment gap. Meetings are used to explain the VA data, discuss the research evidence around the attainment gap, describe the support activities available and hear of initiatives and notable practice taking place in departments. The initial focus has been on those courses with the largest attainment gap. We believe that these meetings have been an essential part of the drive to address the gap.
