Assessing and monitoring the accessibility of web pages are important challenges for ensuring universal accessibility of the web. In this paper, we analyse the quantitative results of the evaluation of web pages using four different metrics with different approaches to the aggregation of results from accessibility audits. The web pages evaluated are from three different Virtual Learning Environments (VLEs). The impact of the different aggregation approaches on the ranges of the values of the resulting metrics and on the ranking of web pages are discussed. We observe that the different approaches may provide different outcomes for comparison purposes, and argue that further investigations on the use of user data to improve the measurement of accessibility should be conducted.
