Definitions for "Sandwich Course"
A degree including a year or more of practical experience in between periods of formal study, similar to co-ops for engineering programs.
Four year courses are usually sandwich courses which require students to spend their third year working in a relevant job (usually paid). Even if you aren't taking a sandwich course, if you find you would like to take a year's break from study, usually to earn money, and get some work experience, it can often be arranged. It's called "intercalating", and you should speak to your course leader about it well in advance.
A course in which periods of study in an educational institution alternate with periods of practical experience in an appropriate work situation in industry, commerce or a profession.
