A Bachelor of Arts and Science(s) (BASc), sometimes as Bachelor of Science and Arts (BScA),^[1] is an undergraduate bachelor's degree conferred by a small number of universities from countries including the United States, Canada,^[2] the United Kingdom,^[3] New Zealand,^[4] Australia, and France.^[5] There is no one set way in which a Bachelor of Arts and Science programme is generally structured but they generally involve students taking interdisciplinary courses from both the liberal arts and the sciences,^[2] and/or require a student to complete the general requirements for a bachelor's degree for two different academic majors (or academic minors) — one that usually leads to a BA degree and one that usually leads to a BSc degree.^[3] The degrees are generally designed to be completed in three to four years, depending on the institution.

Technically speaking, in English-speaking universities it is not an example of a double degree, as universities only confer a single degree.^[6][7] However, Sciences Po, the only French-speaking university to offer the programme, grants a dual Bachelor's degree upon completion.^[5]
