College and university rankings are rankings of institutions in higher education which have been ranked on the basis of various combinations of various factors. None of the rankings give a comprehensive overview of the strengths of the institutions ranked because all select a range of easily quantifiable characteristics to base their results on. Rankings have most often been conducted by magazines, newspapers, websites, governments, or academics. In addition to ranking entire institutions, organizations perform rankings of specific programs, departments, and schools. Various rankings consider combinations of measures of funding and endowment, research excellence and/or influence, specialization expertise, admissions, student options, award numbers, internationalization, graduate employment
