OSSLT: The Complete 2026–27 Guide to Ontario's Grade 10 Literacy Test

By the MapleMind Education Team · Updated July 2026 · 9 min read

What is the OSSLT?

The OSSLT is the Ontario Secondary School Literacy Test, a standardized test that checks whether students meet the province’s minimum literacy standard — the reading and writing skills expected across all subjects up to the end of Grade 9. It’s run by the Education Quality and Accountability Office (EQAO), an agency of the Government of Ontario.

It’s a computer-based test written online at school during regular school hours, and students normally write it in Grade 10. Unlike a course exam, it isn’t testing one subject’s content — it’s testing whether you can read and understand different kinds of texts and write clearly, skills you’ll use in every class and after graduation.

Do you have to pass the OSSLT to graduate?

Yes. Passing the literacy requirement is one of the conditions for earning the Ontario Secondary School Diploma (OSSD), alongside your credits and community-involvement hours. Most students meet it by passing the OSSLT. Students who are unsuccessful can retake the test, or complete the Ontario Secondary School Literacy Course (OSSLC) instead — so the requirement is firm, but there’s more than one path through it.

How is the OSSLT structured?

The test is delivered online in two sessions, with a built-in set of tools like a highlighter and text-to-speech. Here’s the quick breakdown:

So the test is mostly reading comprehension answered through selected-response questions, plus two short pieces of writing where you respond to a prompt in your own words — typically stating and supporting an opinion, and writing a short news-report-style response.

What’s the passing score?

OSSLT results are reported on a scale from 200 to 400, and you need a scale score of 300 for a successful result. A score below 300 is reported as “not yet successful,” which simply means you take another route to the literacy requirement — a retake or the OSSLC — not that graduation is off the table.

When is the OSSLT written in 2026–27?

EQAO runs the test in two windows during the year, and each school chooses its own day inside the window:

Ask your school which window and day you’re scheduled for — it varies by board and even by school, and knowing your date is the first step in building a study timeline.

How to prepare for the OSSLT: a 5-step plan

1. Take the official practice test. EQAO’s practice test looks and works just like the real thing, including the highlighter and text-to-speech tools. Do it early so the platform feels familiar, not new, on test day.
2. Strengthen your reading. Practise the four selection types — narrative, information paragraph, news report, and dialogue — and get quick at spotting the main idea and the details that support it. Most selected-response questions reward careful reading over speed.
3. Practise the two writing tasks. For an opinion response, state your position clearly in the first sentence and back it with specific reasons. For a news-report task, answer the five Ws — who, what, where, when, why. Short and organized beats long and rambling.
4. Build your timing. Rehearse pacing for two sessions of roughly 65 and 75 minutes so you leave enough time to write, not just read. Running out of time on the writing tasks is a common, avoidable way to lose marks.
5. Review with real feedback. The score isn’t the point in practice — the fix is. After each practice piece, get it explained: what made a reading answer wrong, or how to tighten a paragraph, so you’re improving the skill and not just repeating it.

Common mistakes to avoid

• Treating it like a content exam. There’s nothing to memorize — it’s reading and writing skill, built over weeks, not crammed the night before.
• Skipping the writing practice. The two written questions are where careful preparation shows most; don’t spend all your time on multiple-choice.
• Ignoring the online tools. The highlighter and text-to-speech genuinely help — but only if you’ve practised with them beforehand.
• Not reading the full question. On selected-response items, the almost-right option is there on purpose. Read every choice before you commit.
