OSSLT Practice Test: 20 Questions in the Real Format, With Answers Explained

How to use this practice test

Do the questions first. Do not read the answer key beside them.

The value of a practice test is not the score. It is finding out which of the three reading skills breaks down, because they break down for different reasons and they are fixed in different ways. A student who misses questions about what a text says outright is reading too fast. A student who misses inference questions is reading carefully but staying literal. A student who misses connection questions usually understands the text fine and has not been asked to relate it to anything before.

The answer key names the skill behind every question for that reason. Reading and writing support at this level sits under English.

Print it or work on paper. The real test is on a computer, but reasoning is easier to see on paper the first time through.

What the real test looks like

Enough to make the practice make sense. The full picture is on the OSSLT explained.

This set is written to the current test format, the one students will sit in the administration windows EQAO has published: Fall 2026 runs November 3 to 30, 2026, and Spring 2027 runs March 30 to April 19, 2027. Check the format against EQAO's page before using any practice set, this one included. Some of the practice material ranking on Google today still describes the 2018-2019 format.

The OSSLT is written online, in person at school, in two sessions. Session A runs about 65 minutes and Session B about 75 minutes. There are 37 questions in total: 35 selected-response and two written open-response.

The selected-response questions are not all standard multiple choice. EQAO lists "single-selection, multiple-selection, drag and drop, drop-down menu and checklist questions." Students who have only ever practised on four-option multiple choice can lose real time working out how a question wants to be answered. This set uses several of those formats on purpose.

Reading is assessed through four kinds of selection: a real-life narrative, an information paragraph, a news report and a dialogue. This practice test uses one of each, in that order.

Results are reported on a scale from 200 to 400, "with a minimum of 300 required for a successful outcome." Scoring uses Item Response Theory rather than a raw percentage, so there is no number of correct answers here that converts into a scale score. Do not try to calculate one.

The Six O'Clock Shift

My first shift at the garden centre started at six in the morning, which I had not understood was a real time that people worked. Marisol, who ran the nursery yard, handed me a hose and said the hanging baskets came first, every day, before anything else.

I watered them the way I water a house plant. A quick pass, moving down the row, until the soil looked dark.

She came back twenty minutes later and put her hand into one of the baskets, right down to the wrist. Then she showed me her fingers. Dry, to the second knuckle.

"You wet the top," she said. "The roots are at the bottom."

I said I had done all forty of them, and she said she knew, and that I would now do all forty of them again, properly, and that this was the only way anybody learned it. She was not unkind about it. She just went back to loading cedars onto a cart and left me with the hose.

The second pass took an hour and ten minutes. By the end my arms ached from holding the wand up over my head, and I understood something I had been told twice at the interview without hearing it: the job was not watering plants. The job was keeping four thousand living things alive through a July, one at a time, and being the person who noticed when one of them was not.

I worked there three more summers. I still cannot walk past a hanging basket without putting a finger in the soil.

Question 1 (single-selection) According to the selection, what did Marisol do to show that the baskets had not been watered properly?

• A. She lifted a basket down from its hook and weighed it.
• B. She pushed her hand into the soil up to her wrist and showed her dry fingers.
• C. She turned the hose on herself to demonstrate the correct pressure.
• D. She counted the baskets and found that some had been missed.

Question 2 (single-selection) How long did the narrator's second pass at watering take?

• A. Twenty minutes
• B. Forty minutes
• C. One hour and ten minutes
• D. Three summers

Question 3 (single-selection) Which statement best describes Marisol's attitude when she made the narrator start again?

• A. She was angry and wanted the narrator to feel embarrassed.
• B. She was matter of fact, and treated it as ordinary training.
• C. She was disappointed and expected the narrator to quit.
• D. She was uncertain whether the narrator had done anything wrong.

Question 4 (single-selection) The narrator says the job "was not watering plants." What does this suggest about how the narrator came to see the work?

• A. That the watering was actually done by other staff members.
• B. That the real skill was noticing the condition of individual plants.
• C. That the garden centre had more important tasks than watering.
• D. That the narrator preferred loading cedars onto carts.

Question 5 (multiple-selection, choose TWO) The narrator ends by saying they still put a finger in the soil when passing a hanging basket. Which TWO ideas does this ending support?

• A. The narrator never fully trusted Marisol's advice.
• B. A lesson learned through being corrected can last for years.
• C. The narrator continued to work at garden centres permanently.
• D. Habits formed at work can carry into ordinary life.
• E. The narrator resented having to redo the forty baskets.

Section 2: Information paragraph

Read the selection, then answer questions 6 to 9.

Lake-Effect Snow

Lake-effect snow forms when cold air moves across a body of water that is still relatively warm. The water heats the lowest layer of that air and adds moisture to it. Because warm air is lighter than the cold air above it, the moistened layer rises, cools again, and drops its moisture as snow once it reaches land. The effect is strongest when the difference between the water temperature and the air temperature is large, which is why the heaviest lake-effect snowfalls in Ontario tend to arrive in late autumn and early winter rather than in February. By midwinter the lakes themselves are much colder, and parts of them may be frozen, so there is less heat and less moisture available. The bands of snow this process creates can be extremely narrow. It is common for one community to receive a great deal of snow while another twenty kilometres away receives almost none, because the position of a band depends on the direction of the wind crossing the water.

Question 6 (single-selection) According to the selection, what happens to the lowest layer of air as it moves across the warmer water?

• A. It cools and sinks toward the surface of the lake.
• B. It is heated and gains moisture.
• C. It freezes and forms a band of ice.
• D. It reverses direction and returns over the water.

Question 7 (drop-down menu) Complete the sentence using the option that the selection supports. The heaviest lake-effect snow in Ontario tends to fall in late autumn and early winter because at that time of year ______.

• A. the lakes are frozen and reflect more sunlight
• B. the difference between water temperature and air temperature is at its largest
• C. winds across the lakes are slower and steadier
• D. more moisture is held in the soil than in the lakes

Question 8 (single-selection) Why can one community receive heavy snow while a nearby community receives almost none?

• A. Because snow bands are narrow, and their position depends on wind direction.
• B. Because the lakes freeze unevenly across their surface.
• C. Because warmer communities melt the snow as it lands.
• D. Because lake-effect snow only falls at night.

Question 9 (single-selection) A town on the eastern shore of a Great Lake has had very little snow this December, while the lake is unusually cold for the date. Based on the selection, what is the most reasonable explanation?

• A. The lake is too cold to supply much heat and moisture to the air above it.
• B. The town is too far from the lake for lake-effect snow to reach it.
• C. Lake-effect snow does not occur on eastern shores.
• D. December is outside the season when lake-effect snow can form.

Footbridge Reopens After Two-Year Closure

The Mill Street footbridge reopened to pedestrians and cyclists on Saturday morning, two years after an inspection found corrosion in its support beams and the town closed it without warning.

The closure had forced residents of the east side to take a 3.5 kilometre detour along the highway shoulder to reach the shopping district, a route with no sidewalk for part of its length. A residents' group collected 1,400 signatures asking the town to make the repair a priority.

Repairs were delayed twice. The town said the first delay came from a shortage of the steel section required, and the second from the discovery of further corrosion once the deck was lifted.

The final cost was $2.1 million, against an original estimate of $1.4 million.

At Saturday's opening, the town's public works director said the bridge had been rebuilt to a standard that should not require major work for forty years. Members of the residents' group walked across first. One of them told this newspaper that the group had stopped expecting the bridge to reopen at all, and had begun campaigning instead for a sidewalk along the highway.

Question 10 (single-selection) According to the report, why was the footbridge originally closed?

• A. A residents' group requested that it be closed for safety.
• B. An inspection found corrosion in its support beams.
• C. The town needed the steel for another project.
• D. Cyclists and pedestrians had stopped using it.

Question 11 (multiple-selection, choose TWO) Which TWO details in the report suggest that residents had lost confidence in the town's timeline?

• A. The final cost exceeded the original estimate.
• B. The group had begun campaigning for a highway sidewalk instead.
• C. A member said the group had stopped expecting the bridge to reopen.
• D. The bridge was rebuilt to a forty-year standard.
• E. The detour was 3.5 kilometres long.

Question 12 (single-selection) What does the detail about the detour having "no sidewalk for part of its length" most likely suggest about the closure?

• A. That the detour was quicker than crossing the bridge.
• B. That the closure created a safety problem, not only an inconvenience.
• C. That the town had planned the detour route carefully.
• D. That most residents drove rather than walked.

Question 13 (single-selection) A reader wants to know whether the town could have prevented the cost increase. Which piece of information in the report is most relevant to that question?

• A. That 1,400 people signed the residents' petition.
• B. That further corrosion was found only after the deck was lifted.
• C. That the bridge reopened on a Saturday morning.
• D. That the public works director spoke at the opening.

Section 4: Dialogue

Read the selection, then answer questions 14 to 16.

In the Guidance Office

Nadia: I want to drop functions. I got 61 on the last unit test and I have never got a 61 in my life.

Mr. Okonkwo: All right. What do you want to do after Grade 12?

Nadia: Kinesiology. Probably.

Mr. Okonkwo: Then let me show you something before you decide anything. Pull up the admission requirements for the three programs you like most.

Nadia: I already know what they say.

Mr. Okonkwo: Humour me.

Nadia: ... Okay. Two of them want advanced functions.

Mr. Okonkwo: And advanced functions has functions as its prerequisite. So dropping this course does not cost you this course. It costs you two of the three programs, in eighteen months, when you have forgotten why you dropped it.

Nadia: So I just have to be bad at it.

Mr. Okonkwo: No. You have to find out what the 61 was. A 61 after a unit on rational functions is a different problem from a 61 spread evenly across everything. Do you know which one you had?

Nadia: ... No.

Mr. Okonkwo: Then that is the thing to go and find out. Not the course to drop.

Question 14 (single-selection) According to the dialogue, what does Mr. Okonkwo ask Nadia to do before making a decision?

• A. Retake the unit test she scored 61 on.
• B. Look up the admission requirements for the programs she likes.
• C. Speak to her functions teacher about extra help.
• D. Choose a different career path than kinesiology.

Question 15 (single-selection) What is Mr. Okonkwo's main point when he says the decision "costs you two of the three programs, in eighteen months"?

• A. That the consequence of dropping the course arrives long after the choice.
• B. That Nadia should apply to more than three programs.
• C. That advanced functions is offered only once every eighteen months.
• D. That Nadia's marks will improve within eighteen months.

Question 16 (single-selection) Why does Mr. Okonkwo distinguish between a 61 after a unit on rational functions and a 61 "spread evenly across everything"?

• A. Because one of the two results is not officially recorded.
• B. Because a specific gap and a general struggle call for different responses.
• C. Because rational functions are not covered on the final examination.
• D. Because he believes the test was marked incorrectly.

Section 5: Writing questions

Questions 17 to 20 are about writing. They do not refer to the passages above.

Question 17 (drag and drop) A student is writing a paragraph arguing that high schools should start later in the morning. Place these four sentences in the most logical order.

• Sentence W: Sleep researchers have found that teenagers' body clocks shift later during adolescence.
• Sentence X: For both of those reasons, high schools should push their start times back by an hour.
• Sentence Y: Districts that have already shifted their bell times to match that biology report fewer late arrivals in first period.
• Sentence Z: This means a teenager asked to be alert at 8 a.m. is working against their own biology.

Question 18 (single-selection) Which sentence is written correctly?

• A. The coach told the players that practice was cancelled, they went home.
• B. The coach told the players that practice was cancelled; they went home.
• C. The coach told the players that practice was cancelled they went home.
• D. The coach told the players, that practice was cancelled, they went home.

Question 19 (single-selection) Which revision best improves the second sentence below?

The library is open until nine. Which is useful for students who work after school and cannot come earlier in the day.

• A. Which is useful for students who work after school, and cannot come earlier in the day.
• B. Useful for students who work after school and cannot come earlier in the day.
• C. This is useful for students who work after school and cannot come earlier in the day.
• D. Which being useful for students who work after school and cannot come earlier in the day.

Question 20 (single-selection) A student's opinion paragraph opens like this:

"There are many different opinions about school uniforms, and people feel very strongly on both sides of this important issue."

What is the main weakness of this opening?

• A. It is too short to introduce a paragraph.
• B. It contains a grammatical error.
• C. It does not state the writer's own position.
• D. It uses language that is too informal.

The open-response writing task

The two written questions are marked on two separate rubrics: one for how the topic is developed, one for conventions. Neither of them asks whether your opinion is the correct opinion, and that is the part worth understanding before you write a word.

The task

The instruction below is EQAO's standard wording for the opinion piece. The topic is ours.

Write a series of paragraphs expressing an opinion on the following topic. Give reasons for your opinion, and support each reason with details or examples.

Should students be required to complete volunteer hours in order to graduate?

What the marking actually looks for

Each rubric rewards something different, so a piece can score well on one and badly on the other.

Topic development. Is there a clear position, held from the first sentence to the last? Is each reason supported with something specific, rather than restated in different words? A paragraph that says volunteering "builds character, teaches responsibility, and helps you grow as a person" has given one reason three times.

Conventions. Spelling, grammar, punctuation and sentence structure. This is scored on its own. A well argued piece full of run-on sentences loses marks it did not need to lose, and a clean, plainly written piece does not.

How to use this task at home

Set a timer for thirty minutes and write it by hand. Then put it away until the next day and read it once with a single question in mind: does every paragraph give a reason, and does every reason come with a specific example?

Underline the examples. If a paragraph has no underline in it, that paragraph is restating an opinion rather than supporting it. Topic development is one of the two rubrics this task is marked on, and support is what it looks for.

Answer key, explained

Section 1: Real-life narrative

1. B. Skill: understanding explicitly stated ideas. The text says she "put her hand into one of the baskets, right down to the wrist" and showed fingers dry "to the second knuckle." The answer is stated outright. A is wrong because nothing is weighed, C and D describe events that never happen.

2. C. Skill: understanding explicitly stated ideas. "The second pass took an hour and ten minutes." Every wrong option is a real number lifted from somewhere else in the same passage, which is the standard design of a recall question. Twenty minutes is how long Marisol was away, three summers is how long the narrator stayed, and forty minutes is built out of the forty baskets, a number the passage gives twice and never attaches to a clock.

3. B. Skill: making an inference. Nothing in the passage says how Marisol felt. The evidence is behavioural: "She was not unkind about it," she explained the reason, and she went straight back to loading cedars. That is a person treating a correction as routine. Inference questions are answered from what a character does, never from what the reader would feel in their place.

4. B. Skill: making an inference. The sentence continues: the job was "keeping four thousand living things alive through a July, one at a time, and being the person who noticed." The inference is that the real skill is attention rather than the physical act. C is tempting because the passage does mention other tasks, but the narrator is redefining this task instead of ranking it below others.

5. B and D. Skill: making connections. Connection questions ask you to relate the text to a broader idea. The finger in the soil is a habit that outlasted the job, so it supports both the durability of a lesson learned by correction (B) and the carry-over of a work habit into ordinary life (D). A and E both require resentment, and the passage gives none. C overreads: the narrator worked there three more summers, which is not "permanently."

On multiple-selection questions, check all five options against the text before choosing either answer. The question asks for exactly two, so three of the options are there to be rejected, and picking the first one that sounds right leaves you choosing the second from whatever is left.

Section 2: Information paragraph

6. B. Skill: understanding explicitly stated ideas. "The water heats the lowest layer of that air and adds moisture to it." A is the trap worth naming: cooling does happen in this paragraph, but later, after the layer has risen, so A takes a real step of the process and puts it at the wrong stage. C and D describe nothing the paragraph mentions at all.

7. B. Skill: understanding explicitly stated ideas. The paragraph states it directly: the effect is strongest "when the difference between the water temperature and the air temperature is large." A borrows the frozen lakes from the next sentence, where they are the reason the effect weakens by midwinter, and offers them as a reason it is strongest. Drop-down questions look different from multiple choice but are read the same way, so finish the sentence before you look at the options.

8. A. Skill: understanding explicitly stated ideas. "The bands of snow this process creates can be extremely narrow," and their position "depends on the direction of the wind crossing the water." The other three are plausible weather explanations the paragraph never makes. B is the closest of them, because the passage does say parts of a lake may freeze, but it gives that as a reason midwinter snowfall drops, never as the thing that decides where a band lands.

9. A. Skill: making a connection. This question gives a new situation not described in the paragraph and asks you to apply the mechanism to it. The paragraph explains that a cold lake supplies less heat and less moisture. B, C and D each contradict something the paragraph says or invent a rule it never gives. When a question describes a scenario rather than the passage, it is asking you to apply the passage rather than to find a sentence inside it.

Section 3: News report

10. B. Skill: understanding explicitly stated ideas. "An inspection found corrosion in its support beams." A gets the residents' group backwards, since it campaigned to have the bridge repaired rather than closed. C takes the steel shortage, which caused a delay to the repair, and reassigns it to the closure. D describes something the report never says about how much the bridge was used.

11. B and C. Skill: making an inference. Confidence is never mentioned. Two details imply its loss: a member saying they "had stopped expecting the bridge to reopen at all," and the group switching its campaign to a highway sidewalk, which only makes sense if you expect to keep using the detour. A is about money, D is about engineering, E is a fact with no attitude attached.

12. B. Skill: making an inference. A detour along a highway shoulder with no sidewalk is a risk as well as a longer walk. The report never uses the word safety, which is precisely why this is an inference question rather than a recall question.

13. B. Skill: making a connection. The question asks which fact bears on a question the report does not answer. Only one detail speaks to whether the overrun was foreseeable: the further corrosion was found "once the deck was lifted," meaning it could not have been seen beforehand. The other three options are all true and all irrelevant, which is the standard trap here. Relevance is what is being tested.

Section 4: Dialogue

14. B. Skill: understanding explicitly stated ideas. "Pull up the admission requirements for the three programs you like most." A, C and D are all reasonable things a guidance counsellor could say, and none of them is said here. On a recall question the only evidence that counts is the line on the page, so a plausible option with no line behind it is wrong by definition.

15. A. Skill: making an inference. His point is about timing. The cost of the decision does not appear now, when it feels like relief, but in eighteen months, at application time, "when you have forgotten why you dropped it." C misreads eighteen months as a course schedule.

16. B. Skill: making an inference. He is separating a specific gap in one topic from a general difficulty with the course, because the two call for different responses. Neither is stated as such, and neither of the other readings is supported anywhere in the exchange. In dialogue selections, the meaning usually sits in what one speaker is trying to get the other to realise, rather than in any single line.

Section 5: Writing questions

17. Order: W, Z, Y, X. Skill: organisation of ideas. Three of the four sentences point backwards at something, which leaves exactly one that can open the paragraph. Z begins "This means," so it has to follow the research finding in W. Y describes districts that shifted their bell times "to match that biology," and the biology is not named until Z, so Y follows Z. X begins "For both of those reasons," so it cannot land until both reasons are already on the page, which puts it last. W is the only sentence that refers to nothing before it, so W opens. Do a sequencing task in that order: find every backward-pointing word first, and the sequence assembles itself. A paragraph built this way ends on its recommendation, which is not the same advice as question 20 gives for the opinion task, where you write the sentences yourself and should state your position in the first one.

18. B. Skill: conventions. Two complete sentences joined by a semicolon. A is a comma splice, which is a common convention error and the one this question is built around. C is a run-on with no punctuation at all, and D adds a comma that separates the verb from its clause.

19. C. Skill: conventions. The underlined text is a sentence fragment: "Which" leaves it dependent with nothing to attach to. Replacing "Which" with "This" makes it a complete sentence. B removes the subject and verb entirely, leaving another fragment. D adds "being" and makes it worse.

20. C. Skill: topic development. The opening describes a debate without joining it. On an opinion task, the position should be visible in the first sentence. The sentence is grammatically fine, which is what makes this question about development rather than conventions, and it is why the two are scored separately.

Where a certified teacher fits

Most of what is on this page a student can do alone. What a page cannot do is turn one set of misses into a plan: which skill to work on first, how much time it needs, and how the OSSLT fits alongside the courses your child still has to take.

Genie works only with Canadian Certified Teachers, licensed by a provincial governing body such as the Ontario College of Teachers. Certification is verified before a teacher ever sees a student profile: the certificate number and issuing body are checked against the provincial registry, alongside a live government-ID match. Genie calls that the Trust Engine.

A certified teacher does more than reteach the material. They can chart which courses a student needs to reach the program they are aiming at, then focus the teaching on the subject areas that get them there. Matching is by course, pace and personality, and parents get a record after every lesson of what was covered and what their child understood.
