The Course Type is to identify if the course is in preparation for the college or university level. Open courses are designed to meet the requirements of either college or university prerequisites. Course code is a standard identification established by the Ministry of Education in Ontario of credit courses taken by a student. The course code will be used on report cards, transcripts, and any other documents that will reflect Ontario credit courses. It is a combination of letters to identify subject area, numeric level, and academic level of difficulty. Substitution of compulsory courses can only be made by the principal for students with special needs. The range of courses may include the following:

  • Learning Strategies 1: Skills for Success in Secondary School
  • Discovering the Workplace
  • Designing Your Future
  • Leadership and Peer Support
  • Advanced Learning Strategies: Skills for Success After Secondary School
  • Navigating the Workplace

A maximum of 1 credit earned for a learning strategies course may be used as a substitution for a compulsory credit course. There is a limit of 3 substitutions. Other credit courses in Business, Social Sciences, Science, and Technology are available on an individual’s needs basis.


Explanation of a Course Code

Each credit course is given its own course code to identify subject area, grade or language level, course type, and program differentiation.

For example, ENG3U1 is an English grade 11, university, regular course

Subject Area is categorized by the first 3 letters: eg. “ENG”

B = Business Studies

C = Canadian and World Studies

E = English, English Literacy Development, English as a Second Language

G = Guidance and Career Education

L = Classical, International and Native Languages

M = Mathematics

S = Science

T = Technological Education


Grade or Language level is given a numeric or alphabetic value: eg. “3”

Grades 1 = grade 9

2 = grade 10

3 = grade 11

4 = grade 12

Languages A = level 1

B = level 2

C = level 3

D = level 4

E = level 5


Course type is indicated by a letter to determine the content focus: e.g. “U”

C = College

D = Academic

M = College or University

O = Open

P = Applied

U = University

N = Non-Credit


Program Differentiation is the 6th character in the course code: e.g. “1”
