The Times Higher Education rankings are strong in academic focus and diverse teaching metrics, but do not include employer-specific metrics. Additionally, the rankings may not include all specialist institutions.

The QS World University Rankings are designed to meet the needs of prospective students, with more weight given to student-centric metrics such as staff/student ratio, international recruitment and employer opinion. The rankings are balanced between qualitative and quantitative data, but give less weight to research than some other rankings.

The ARWU rankings reflect the presence of elite academics and the future academic success of graduates. However, they do not directly assess the quality of education at a university or take into account other aspects of university performance.
