Higher, post-secondary, tertiary, or third level education refers to the stage of learning that occurs at universities, academies, colleges, seminaries, and institutes of technology. Higher education also includes certain collegiate-level institutions, such as vocational schools, trade schools, and career colleges, that award academic degrees or professional certifications.

The right of access to higher education is mentioned in a number of international human rights instruments. The UN International Covenant on Economic, Social and Cultural Rights of 1966 declares, in Article 13, that "higher education shall be made equally accessible to all, on the basis of capacity, by every appropriate means, and in particular by the progressive introduction of free education". In Europe, Article 2 of the First Protocol to the European Convention on Human Rights, adopted in 1950, obligates all signatory parties to guarantee the right to education.

Higher education is an educational level that follows the completion of a school providing a secondary education, such as a high school, secondary school, or gymnasium. Tertiary education is normally taken to include undergraduate and postgraduate education, as well as vocational education and training. Colleges, universities, and institutes of technology are the main institutions that provide tertiary education (sometimes known collectively as tertiary institutions). Examples of institutions that provide post-secondary education are vocational schools, community colleges, independent colleges (e.g. institutes of technology), and universities in the United States, the institutes of technical and further education in Australia, CEGEPs in Quebec, and the IEKs in Greece. They are sometimes known collectively as tertiary institutions. Completion of tertiary education generally results in the awarding of certificates, diplomas, or academic degrees.

David J. Helfand was the chair of the Department of Astronomy at Columbia University as well as the co-director of the Columbia Astrophysics Laboratory. He has also served as part of the university's Physics Department. His stated research interests include radio surveys, the origin and evolution of neutron stars and supernova remnants, and active galactic nuclei. Helfand has been instrumental in the creation of general education classes oriented around the sciences, developing a course, Frontiers of Science, that has subsequently become part of the Core Curriculum of Columbia College, the university's undergraduate liberal arts and sciences division.

Dr. Helfand joined Quest University in British Columbia, Canada, as a Visiting Tutor in 2007 and now serves as Quest's President. On July 18, 2011, a Quest media person reports that Helfand has taken a long term leave of absence from Columbia.

Helfand holds a Bachelor of Arts from Amherst College and a Ph.D. from the University of Massachusetts Amherst.

Milton Friedman (July 31, 1912 – November 16, 2006) was an American economist, statistician, and author who taught at the University of Chicago for more than three decades. He was a recipient of the Nobel Memorial Prize in Economic Sciences, and is known for his research on consumption analysis, monetary history and theory, and the complexity of stabilization policy. As a leader of the Chicago school of economics, he influenced the research agenda of the economics profession. A survey of economists ranked Friedman as the second most popular economist of the twentieth century behind John Maynard Keynes, and The Economist described him as "the most influential economist of the second half of the 20th century…possibly of all of it."

Friedman's challenges to what he later called "naive Keynesian" (as opposed to New Keynesian) theory began with his 1950s reinterpretation of the consumption function, and he became the main advocate opposing activist Keynesian government policies. In the late 1960s he described his own approach (along with all of mainstream economics) as using "Keynesian language and apparatus" yet rejecting its "initial" conclusions. During the 1960s he promoted an alternative macroeconomic policy known as "monetarism". He theorized there existed a "natural" rate of unemployment, and argued that governments could increase employment above this rate (e.g., by increasing aggregate demand) only at the risk of causing inflation to accelerate. He argued that the Phillips curve was not stable and predicted what would come to be known as stagflation. Friedman argued that, given the existence of the Federal Reserve, a constant small expansion of the money supply was the only wise policy.
