The University Selection Test ( or PSU) was a standardized test used for college admissions in Chile, made by the Department of Evaluation, Measurement and Educational Register (Departamento de Evaluación, Medición y Registro Educacional or DEMRE) by mandate of the Board of Chilean Universities' Headmasters (Consejo de Rectores de las Universidades Chilenas, or CRUCH). Since 2003, it had replaced the Prueba de Aptitud Académica (PAA) which had been in use since 1966, until its eventual termination in 2020. A temporary test (Prueba de Transición) was used while the Prueba de Admisión a la Educación Superior (PAES) was in development.

The PSU was given once a year, usually between November and December. It was necessary to take the test to apply to universities ascribed to the CRUCH, known as Traditional Universities. The only requirement to take this test was to have completed high school.

Format The PSU itself was a set of four separate tests, which were taken in two days. Out of these four:

Two were required (Reading Comprehension and Mathematics) Two were optional, yet it was required to choose one History and Social Studies Science: This test had a common module of Biology, Physics and Chemistry (referring to the curriculum of the first two years of secondary education) and three elective modules from which one is chosen (Biology, Physics or Chemistry - referring to the curriculum of the 3rd and 4th years of secondary education)

The maximum score was of 850 points, and the minimum, 150 points.
