Fundamentally… nothing! At UFV, the same rules and regulations apply to both internships and practicums. Students receive academic credit for engaging in an unpaid learning experience that is supervised by a business, NGO, organization, charity, or community group. The academic work they do associated with the internship or practicum is supervised and assessed by a UFV instructor. Both types of experiences require students to submit applications, sign waivers and get contracts signed, etc.
Such experiences are usually called practicums in Canada, but internationally, and even here at home, these types of experiences are called internships. We use both, therefore, to recognize the global context but we follow the rules for practicums to set up all experiences.
