University rankings are systems that evaluate and compare universities based on various criteria, such as academic performance, research output, and student satisfaction. These rankings help prospective students and parents make informed decisions about where to study. Commonly referenced rankings include QS World University Rankings, Times Higher Education, and Academic Ranking of World Universities. Different ranking systems use distinct methodologies, which can lead to variations in results. Factors like faculty quality, international diversity, and funding are often considered. While rankings can provide useful insights, they should be viewed as one of many tools in assessing a university's overall quality and fit for individual needs.
