Program details

Overview

If you meet all the necessary academic requirements, you will be able to participate in an unpaid field placement that will allow you to acquire hands-on experience in a formal work environment. You may have a shared responsibility for securing a placement. The placement may take place after the third semester of classroom studies, extending the length of the program by one month. Successful completion of this placement is a requirement for graduation.

Requirements

Admission Requirements: Domestic admission requires an Ontario Secondary School Diploma (OSSD) or equivalent, or acceptance as a mature applicant, with the only stated subject prerequisite being English at the Grade 12 C or U level or an equivalent course; Grade 12 mathematics is recommended, though not required, for success in the program. Canadian citizens and permanent residents short of the English prerequisite may instead qualify by passing Seneca's pre-admission test, and applicants who do not meet the subject requirement are directed to upgrading options. International applicants must additionally meet Seneca's own published English-language requirement, with further documents or assessments requested where needed; neither this program's page nor its admission-requirements page states an IELTS, TOEFL or other numeric test score, or a minimum grade average for this diploma.
