Higher education in the United States is an optional final stage of formal learning following secondary education. Higher education, also referred to as post-secondary education, third stage, third level, or tertiary education occurs most commonly at one of the 4,726 Title IV degree-granting institutions, either colleges or universities in the country. These may be public universities, private universities, liberal arts colleges, community colleges, or for-profit colleges. High visibility issues include greater use of the Internet, such as massive open online courses, competency-based education, cutbacks in state spending, rapidly rising tuition and increasing student loans.
According to the National Student Clearinghouse, US college enrollment has declined for five consecutive years and is projected to continue declining for the next two decades.
Strong research and funding have helped make American colleges and universities among the world's most prestigious, making them particularly attractive to international students, professors and researchers in the pursuit of academic excellence.
Unlike the tertiary education system of the UK and Australia, American education is unique in the world to place strong emphasis on Liberal Arts education in its higher education curriculum.
As of 2012[update], the latest figures available in 2015, the US has a total of 4,726 Title IV-eligible, degree-granting institutions: 3,026 4-year institutions and 1,700 2-year institutions. The US had 21 million students in higher education, roughly 5.7% of the total population. About 13 million of these students were enrolled full-time which was 81,000 students lower than 2010.
