TASI has been held each summer since 1984. In past years it was held at Michigan, Yale, Santa Cruz, Santa Fe, Brown, and since 1989 at Boulder. Each year typically some sixty of the most promising advanced theory graduate students in the United States, along with a few beginning postdoctoral fellows and experimental graduate students, have attended TASI. TASI 2021 will be held from Monday, June 7 to Friday, July 2 online. The emphasis has shifted from year to year, but typically there have been courses of lectures in phenomenology, field theory, string theory, mathematical physics, and particle-astrophysics interface, as well as seminars on other theoretical and experimental topics. It has been highly successful, especially in introducing the students to a much broader range of ideas than they normally experience in their home institutions while working on their (often narrow) dissertation topics.

The themes of the previous three TASI's were "The Obscure Universe: Neutrinos and Other Dark Matters," "The Many Dimensions of Quantum Field Theory", and “Anticipating the Next Discoveries in Particle Physics". The theme of TASI 2021 will be "Black Holes, Quantum Information, and Dualities".

Like any classroom environment, the success of TASI depends strongly on preserving a friendly, relaxed, and collegial atmosphere for all participants, including both students and lecturers. The organizers are committed to making sure that everyone feels welcome in all of the lectures, discussions, coffee breaks, and any of the more informal parts of the school as well.

If you experience or witness any disruptive or unwelcome behavior, such as harassment, intimidation, or discriminatory behavior or language, please speak with one of the local or scientific organizers immediately. We reserve the right to take disciplinary action against students who violate this code of conduct, including removal from the remainder of the school.
