The United States Particle Accelerator School (USPAS or School) is a National Graduate Program that provides graduate-level educational programs in the science of particle beams and their associated accelerator technologies that are not otherwise available to the scientific and engineering communities.

The USPAS conducts two academic sessions annually, the Winter Session held in January and the Summer session held in June. Sessions are two weeks in duration and offer a choice of 12 to 15 courses. A two-week course has at least 45 contact hours plus nightly mentored homework sessions and exams. Since initiating its program of rigorous academic courses in 1987, USPAS in partnership with major American research universities has conducted more courses and issued more academic credit in accelerator science and technology than any university in the world. Because its continuing, rigorous program of academic courses is unmatched by other programs worldwide, the USPAS has become a well-recognized contributor to the education of accelerator scientists and technologists internationally.

During the term of the present USPAS Director Barletta, the USPAS has been training more early-career scientists and engineers than ever. Attendance has risen from an average of ~129 students per session to greater than 145 students per session. The USPAS offers extensive scholarship support to degree-seeking students who take its courses for credit. Course offerings for upcoming sessions, scholarship applications and extensive course materials from previous courses can be found on the USPAS website.

The USPAS also promotes the writing and publication of textbooks devoted to accelerator science and technology. It is a partner with CERN, the Budker Institute for Nuclear Physics in Russia, and the Asian Committee on Future Accelerators in organizing the Joint International Accelerator School
