Teaching the OSSLT: a four to five month plan for your class

The OSSLT is not a unit you can cram for. EQAO grounds it in the reading and writing expectations for every subject up to the end of Grade 9, so students need time to build those skills, practise them in the test’s format and get feedback on their writing again and again. The plan below spreads that work over four to five months before your school’s test date, with one or two short practice sessions a week.

Why start four to five months out

Reading and writing skills grow slowly. A student who writes one practice essay a week for four months, gets feedback on each one and fixes the weakest paragraph improves far more than one who writes five essays in the week before the test. Starting early also gives you time to find the students who need extra support while there is still time to help them. For the spring window, that means starting in November or December. Students writing in the fall window get the most from starting in the spring of Grade 9 and picking up again as soon as school starts in September.

What the OSSLT measures

Students write the test online in two sessions of about 65 and 75 minutes. There are 37 scored questions worth 78 raw points: four reading selections with 23 selected-response questions and one written answer, then 12 writing questions and an opinion essay. The essay alone is worth 20 points, about a quarter of the test.

The questions check six skills, three in reading and three in writing:

• Reading: finding information that is stated directly, making inferences about ideas that are implied, and connecting ideas in the text to what students already know.

• Writing: developing a main idea with enough specific supporting details, organizing ideas so they connect, and using spelling, grammar and punctuation well enough that errors don’t get in the way.

The two written answers are scored by trained educators with EQAO’s rubrics, as first-draft writing. Every code on those rubrics is explained in our OSSLT marking guide.

A four to five month plan

Each phase builds one group of skills with short, regular practice in the test’s format. Keep a weekly rhythm: one reading task and one piece of marked writing, with feedback students act on before the next one. Adjust the order to what your diagnostics show.

Month 1: Find out where students start

Run a diagnostic. EQAO’s free practice test uses the same online platform and question types as the real test, and teachers can also set up a practice session through EQAO’s e-assessment system. For a paper version, our printable OSSLT practice test PDF has an answer key that names the skill behind every question, so you can record results by skill, not just by total. Set a baseline for every student.

Month 2: Reading skills

Work through the three reading skills a few weeks at a time. For stated information, students prove every answer by underlining the exact sentence before choosing a letter. For vocabulary, they swap each answer choice into the sentence and keep the one that still makes sense. For inference, the hardest skill for many students because the answer isn’t written down, use a three-part frame: the text says, I think, because.

Month 3: The two written answers

Teach the reading written answer first. It is coded from 10 to 30, and a 30 needs accurate, specific and relevant ideas from the selection: answer the question in the first sentence, support it with two specific details, and explain how each one supports the answer. Then move to the opinion essay with a four-part plan: an opening with a clear opinion, one paragraph per reason with a specific detail, an optional sentence on the other side, and a closing that returns to the opinion. The line between a 40 and a 50 is specific details. The opinion essay guide has an annotated sample.

Month 4: Writing questions and a second diagnostic

The 12 writing questions cover sentence structure, organization and conventions: run-ons, fragments, topic and concluding sentences, transitions and paragraph order. Mid-month, run a second diagnostic and compare it with the baseline. Regroup students by the skills that still need work.

The final weeks: Full practice and targeted support

Run a timed practice under first-draft conditions, then spend the remaining sessions on each group’s weakest skill. Keep the weekly marked writing going right up to test day, so students go in with a routine they trust.

Find the students who need support early

After the first diagnostic, group students by the skills they missed, not by their total. Three groups usually cover most of a class: students who miss inference questions, students whose written answers lack specific details, and students whose errors distract from what they are saying. Check each group at every diagnostic, so you can see who is moving and who needs more time.

Activities that work in any subject

Because the OSSLT draws on literacy expectations from every subject, these short activities fit into science, history or geography as easily as English:

• Headline swap. Students write a new headline for an article or textbook section, then compare which headlines capture the main idea.

• One specific detail. Give a general statement and have students rewrite it with a time, a place, a number or an example a reader can picture.

• Code the sample. The class codes an anonymous opinion essay with both rubrics, then discusses what would move it up one code.

• Inference exit slip. One inference question, answered with the frame “I think … because the text says …”.

• Error hunt. Students find the three errors in a paragraph that most get in the way of meaning, such as a run-on, a missing comma or a wrong word.

Where Litguide fits

Litguide is built for exactly this kind of steady, semester-long practice. Students work through lessons and OSSLT-style practice every week and get each piece of writing marked against the rubrics in seconds, and teachers see results by skill as they change over the months, so the plan runs on real data instead of guesswork. Schools and boards license it. Book a demo to see it with your own students’ writing.
