A Bachelor of Applied Science is an undergraduate academic degree awarded for a course of study that generally lasts three years in the UK or four or five years in North America.

A Bachelor of Applied Science usually requires a student to take a majority of their courses (usually 3/4) in the applied sciences, specialising in a specific area, such as

• Engineering - General
• Chemical engineering
• Mechanical engineering
• Computer engineering
• Electrical engineering
• Biological engineering
• Civil engineering
• Software engineering
• Mechatronics engineering

A Bachelor of Applied Science does not necessarily require the study of an engineering discipline. Majors may be taken in more practical applications of sciences such as applied physics or applied chemistry. Most universities that offer this degree require a rigorous course schedule.

A graduate of a Bachelor of Applied Science program receives the designation BAS, B.ASc., B.App.Sc or B.Appl.Sc for a major or pass degree and BAS(Hons), B.ASc.(Hons) or others for an honours degree.
