The mission of the Association of Part-time Undergraduate Students (APUS) is to ensure that part-time undergraduate students have access to the full range of programs, services and resources at the University of Toronto in order to improve the quality of the part-time undergraduate educational experience.

APUS works to ensure a variety of post-secondary educational opportunities are available for students who, for any reason, choose to study part-time. APUS believes that education can be combined with work, family and other activities and that part-time study represents a viable option for students. APUS achieves its mission by representing part-time undergraduate students throughout the decision-making processes of the University and of governments, by acting as a voice for the concerns of APUS members and by maintaining active communication with all part-time students. APUS strives to ensure that services are provided to meet the academic and social needs of part-time undergraduates on all three campuses at the U of T.

APUS services include the APUS Health & Dental Plan, APUS Bursary Program, APUS Tax Clinics, APUS Student Study Space and Lounge, Printing Services, Academic Support Workshops & Advocacy, Financial Aid Workshops for Part-Time Students, and Lunch & Learn Career Workshops.
