OSSLT Prep: How to Pass the Ontario Literacy Test

By Connor Engels, OCT · 27 July 2026

What the OSSLT is, and why it matters

The Ontario Secondary School Literacy Test is run by EQAO and is a requirement for the Ontario Secondary School Diploma. Students normally write it in Grade 10. It is not a subject exam. It does not test whether you have read a particular novel or remembered a particular set of terms. It tests whether you can read unfamiliar material and write clearly about it under time pressure.

That distinction matters more than anything else in this article. Students who treat the OSSLT like a content test try to study facts, find there are none, and conclude there is nothing to prepare. There is plenty to prepare. It is just skill practice rather than memorisation.

What the test asks you to do

The test is written online and is built from two kinds of work:

• Reading. Short passages of different types, including informational text, a news report, a graphic text such as a chart or diagram, and a short narrative. Each is followed by questions, some multiple choice and some requiring a written answer.
• Writing. Both short written answers and longer pieces, where you develop a point of view or write in a specific form.

The exact mix of tasks has been adjusted since the test moved online, so before you build a study plan, open the current sample test on the EQAO website and look at this year's real format. Working from an outdated practice booklet is the most common preparation mistake I see, and it is entirely avoidable.

Where students actually lose marks

After years of marking student writing, the failures cluster into a handful of predictable patterns. Almost none of them are about vocabulary or intelligence.

1. Answering a question the test did not ask

A question asks you to explain why the author included a detail, and the student explains what the detail is. The answer is accurate and earns nothing. Before writing, underline the question's verb. Explain, describe, identify and compare are asking for different things.

2. Giving an opinion with no evidence

Written-answer questions almost always want a point plus support from the passage. A confident assertion with nothing behind it reads as a guess. One specific detail from the text lifts a weak answer more than another two sentences of opinion.

3. Writing too little

Students who are nervous write short, hoping brevity hides uncertainty. It does the opposite. A developed answer gives the marker something to reward. If a task asks for a paragraph, write a paragraph.

4. Running out of time on the reading

Students read every passage as though it were a novel. Read the questions first, then the passage. You are reading with a purpose, not for pleasure.

5. Ignoring the graphic text

Charts, diagrams and infographics get skimmed because they look like decoration. They carry the same weight as prose, and the questions on them are often the most straightforward marks on the test.

A four-week preparation plan

Four weeks at roughly two hours a week is enough for most students. More than that has diminishing returns.

1. Week 1 — see the real thing. Do a full official practice test in one sitting, timed. Do not study first. The point is a baseline and a shock to the system: almost every student finds the test less frightening after seeing it once.
2. Week 2 — reading. Work through reading sections only. For every question you get wrong, write one sentence explaining why the correct answer is correct. That sentence is where the learning happens, not in the answer itself.
3. Week 3 — writing. Practise the written tasks with a timer. Write in full, then reread and mark your own work against the question. Ask: did I answer what was asked, and did I support it?
4. Week 4 — a second full test, then rest. Compare against Week 1. Review only your recurring mistakes. Do not cram the night before; sleep does more for reading comprehension than an extra hour of practice.

Practical strategies for test day

• Read the question before the passage. You will read faster and retain what matters.
• Answer in the language of the question. If it asks why the writer uses a comparison, begin "The writer uses this comparison to…". It forces you onto the right track.
• Quote briefly. A few words from the text is usually enough. Long quotations eat time and add nothing.
• Leave nothing blank. There is no penalty for a wrong answer and there is a guaranteed zero for an empty box.
• Watch the clock, not the section. Know roughly where you should be at the halfway mark.

If you don't pass

Not passing on the first attempt is more common than students expect and it does not put your diploma at risk on its own. Students who are unsuccessful can rewrite the test, and there is also the Ontario Secondary School Literacy Course, which satisfies the literacy requirement through coursework instead. Students with an IEP may be eligible for accommodations or a deferral, arranged through the school.

Talk to your school's guidance office about which route fits. Both paths lead to the same diploma, and neither appears on a university application as a mark.

The honest summary

The OSSLT is a reading-and-writing skills test that most students pass. The preparation that works is not memorisation but timed practice on the real format, plus deliberate attention to the handful of mistakes that cost the most marks. Four weeks of focused work beats four months of worrying about it.
