The role of the Quality Assurance Agency (QAA) is to check how well institutions manage their responsibilities for maintaining academic standards and quality. One of the ways it does this is by visiting individual institutions, normally once every six years. This visit is called Higher Education Review, which focuses on an institution's provision against the QAA's Quality Code.
The QAA last visited the School in March 2011. The results can be found in the QAA's report, which you can find here.
