One of the main reasons for getting a good education is to obtain the best job possible after graduation. One important factor employers consider when hiring is the quality of the education of all the candidates. If you have the option of attending a top-notch university, your career opportunities will broaden significantly. If you aren’t fortunate enough to attend one of the best universities in the world, then at least you can look closely at the best and see what factors make them so powerful and find schools that strive to provide some of the same elements among their educational offerings. The Times Higher Education – QS World University Rankings publishes an annual listing of the best universities in the world. The rankings are based on academic peer review, employer review, faculty-student ratio, citations per faculty, and international teachers and students. According to their results for 2008, Harvard University is the top-ranked university in the world. Located in Cambridge, Massachusetts, Harvard is the oldest institution for higher learning in America and enjoys a strong reputation grounded in the success of the graduates, the top quality research coming from the university, and the exceptional teaching faculty. Behind Harvard, the next best universities in the world include Yale, Cambridge, Oxford, and California Institute of Technology to round out the top five. Of the top 100 universities around the world, 42 are from the United States, 36 are from Europe, and 22 from Asia Pacific. The United States dominates the top of the list with 11 of the top 15 universities.
