What does the right OSSD plan look like? It starts with the student, not the timetable.

OSSD students apply with the standing of a Canadian domestic student. The system runs on credits rather than one decisive exam, with 300+ courses to choose from, so the work done through the year counts and a student can build around what they are good at.
Besides OSSD, the familiar international programmes are A-Level, IB (IBDP) and AP. All three are demanding, ask a lot of a student in both subject ability and English, and offer limited places, and some students cannot finish them. All three also end in a standardised exam at a fixed time and place, which leaves one test deciding everything.
So who are those three for?
Against those three, OSSD lets a student apply to the world's best universities on six Grade 12 marks with no major exam, which makes it the friendliest of the four to almost any student.
Here are the four programmes side by side. OSSD is the easiest of them and the best fit for most students applying from abroad: no single decisive exam, no major sitting, no uniform standardised assessment.
| OSSD - Ontario Secondary School Diploma | A-Level* - UK high school qualification | IBDP* - International Baccalaureate Diploma Programme | AP* - Advanced Placement | |
|---|---|---|---|---|
| Length | 1-3 years, and 1 year is possible | 2 years | 2 years | 1-2 years |
| Overall difficulty | Easy | Moderate | Hardest | High |
| Course difficulty | Lower: moderate in the humanities, low in the sciences | Moderate | High | High |
| English required | Standard | Higher | Highest | Higher |
| Exam venue and format | School-set examinations, taken in school | Fixed venue, global sittings 2-3 times a year | Fixed venue, global sittings twice a year | Fixed venue, global sitting once a year |
| Form of assessment | 70% coursework plus 30% final examination | One standard examination, one grading scale | One standard examination, one grading scale | One standard examination, one grading scale |
| Converts to university credit | Yes | No | No | No |
| Community service required | Yes | No | Yes | No |
| Overall | A strong fit for students applying from abroad · simple and quick, with no exam sitting | Harder for overseas students on cultural grounds · heavily exam-weighted | Strong on essays and practical work · tied to the diploma · six subjects to pass, a heavy load | A pass is worth first-year standing · straight to the examination |
An OSSD diploma and transcript get a student a better answer from the university they want.
The test sits at about IELTS 5.5, while a Canadian university usually asks 6.5 or more, so most students pass first time.

An OSSD needs 4 English credits, and graduation asks for English at Canadian Grade 10 level or above.
ESL stands for English as a Second Language, also called ELL: the language courses Canadian schools run for students whose first language is not English.
Finishing ESL is an OSSD graduation requirement. The ESL record also counts as evidence of English ability at the top universities, and it saves the student a separate language test such as IELTS.
| ESL level | A | B | C | D | E |
|---|---|---|---|---|---|
| IELTS equivalent | Under 4.0 | 4.0-4.5 | 5.0 | 5.5 | 6.0-6.5 |
Many leading universities accept the Grade 12 OSSD English mark as their evidence of English, so students do not sit IELTS or TOEFL separately.
We assess and place students against the Ministry's ESL curriculum across five levels, so the base is rebuilt level by level and the weak areas get the attention.
Online, in person, or both, so the format never limits the student.
✓ Online: live classes taught by licensed teachers
✓ In person: face to face with local Canadian teachers
Content and method adjust as we go. In class: materials issued ➡️ after class: work marked ➡️ testing: progress checked on a cycle
When can a student join OSSD, and what does the plan look like after that? We build a plan for each entry point so students use their holidays and finish OSSD in one to three years, while keeping their domestic coursework and ending with both diplomas.
In the first year the student puts everything into ESL and English, which every later subject depends on. It is also the year they are getting used to a new way of studying, so the course load stays light.

| Grade 12 (online or in person) | Grade 12 English | Grade 12 Mathematics I | Grade 12 Mathematics II | Grade 12 Mathematics III | Grade 12 Physics | Grade 12 Chemistry |
Students joining after Grade 10 usually have English at ESL level B or above, so placement can skip part of the ESL sequence. The Canadian curriculum is lighter than the domestic one, so they deepen their English inside familiar material and get used to how North America teaches.

Finish OSSD in a year? It can be done. Start in the summer before Grade 12, clear ESL and some Grade 11 courses, then use weekends and the gaps in the Grade 12 year for the rest. A student stronger in the humanities can swap arts and business courses in for math, physics and chemistry, and score high in what they are good at.
| Term | Course 1 | Course 2 | Course 3 | Course 4 |
|---|---|---|---|---|
| Summer before Grade 12 (online, ESL A/B) | ESL Level 1-2 ESLC | ESL Level 3 ESLD | ESL Level 4 ESLE | ESL Level 5 |
| (same period) | Grade 11 English | Grade 11 Physics | Grade 11 Chemistry | |
| Grade 12, first term (online or in person) | Grade 11 Mathematics | Grade 12 Mathematics I | Grade 12 Mathematics II | Grade 12 Mathematics III |

OSSD leaves room for the student in front of you: choose what you are good at, and score high in it. We build different plans for students heading into science and engineering, into the humanities and business, and into the arts.
Science courses are the prerequisites for engineering and science degrees, and the Grade 12 science marks decide where a student ends up. These are the subjects they usually take:
| Grade 12 Mathematics I - Advanced Functions MHF4U | Grade 12 Mathematics II - Calculus and Vectors MCV4U | Grade 12 Mathematics III - Data Management MDM4U | Grade 12 Physics SPH4U | Grade 12 Chemistry SCH4U | |
|---|---|---|---|---|---|
| Content | Quadratic and trigonometric functions and related topics | Derivatives and vectors | Mostly foundational statistics · half quantitative, half written · built on understanding rather than proof | Broader in scope than the domestic course, and lower in difficulty | Broader in scope than the domestic course, and lower in difficulty |
| Domestic equivalent | 60% Grade 10 math, 40% Grade 9 math | Grade 11 math | Grade 10 physics, second term | Grade 11 chemistry, first term |
Domestic science teaching is strong, and OSSD science is much lighter by comparison, so students applying from China average around 95 in it.

Grade 12 humanities courses are mostly optional, so the compulsory Grade 12 English course (ENG4U) is the example here:
Language makes the humanities harder for students applying from China, and OSSD humanities marks average in the 80s. The breadth of OSSD options lets these students meet varied material early and arrive at their major ready for it.

OSSD assesses a student in several ways, looking at knowledge, thinking, communication and application, with feedback along the way. Most of the mark comes from the work done through the year: assignments (individual and group) / oral presentations (individual and group) / topic reports (individual and group) / individual written tests. Students build academic ability, and in the group work they build leadership, communication and collaboration.
Beyond subject knowledge, students develop reasoning, academic writing and presentation, which is the ground for study, work and a career. In every course a student lifts both academic and English ability, and the group reports teach them to work with people who see things differently, which is where collaboration and leadership come from. OSSD counts what a student accumulates through the year rather than a scramble before an exam, so good habits and real capability come out of the system itself.
| OSSD Grade 12 course | Average mark |
|---|---|
| English | 80-85 |
| Functions | 93-97 |
| Calculus | 91-96 |
| Data Management | 90-95 |
| Physics | 93-96 |
| Chemistry | 90-95 |
| Six-course average used on applications | 89.5-94 |
Leaving aside the choice of major and the universities that ask for a standardised test, an average of 89.5-94 is enough to apply anywhere in the world
25% receive an offer from a top 20 university worldwide / 50% from a top 40 / 70.6% from a top 50 / 100% receive a direct offer from a top 100 university, with no foundation year
More than 70% of OSSD graduates go to a top 50 university.
