MarkScanner

An invitation for Ontario high-school math teachers

Less time marking. More useful feedback.

MarkScanner helps you mark handwritten math tests and quizzes using a rubric you approve. Get draft marks and specific feedback for each student, while keeping your paper assessments and classroom routine.

Try it free for one month, with personal help getting started.

Email Oscar to arrange your free month See a sample

No credit card. No automatic billing. Your free month starts on a date you choose with Oscar, not when you read this page.

  • Students keep writing on paper.
  • You approve the rubric and final grades.
  • No student accounts needed.

See the work, the draft marks, and the feedback

See what MarkScanner does with a handwritten response

Follow one sample response from the student’s working to the feedback they receive. For fuller walkthroughs with four students each, see the worked examples, or read more about MarkScanner for Ontario teachers.

  1. Step 1

    The handwritten work

    See the original response, including the steps the student took and where they made a mistake.

  2. Step 2

    The draft marks and feedback

    MarkScanner uses the approved rubric to propose a mark, including partial credit, and explain the result question by question.

  3. Step 3

    Your review

    Check the draft against the original work. Change marks or comments and investigate flagged answers before returning the results.

  4. Step 4

    The student's feedback sheet

    Print feedback showing what the student did well, where they went wrong, and what to practise next.

Your rubric. Your review. Your final grades.

You can still read every student’s paper and see how they approached each question. MarkScanner helps with the repetitive scoring and comment writing, while you make the assessment decisions.

Works with the tests you already give

Keep your classroom routine

Students write on paper and show their work, just as they do now. No student computers or accounts are required.

MarkScanner works from your assessment materials and the rubric you approve.

Have these ready

  • A blank copy of your test or quiz.
  • Your worked solutions or answer key.
  • Scanned student work.

Already have a rubric or specific marking instructions? Include those too.

One PDF can contain the whole class set and assessment materials.

Use your school photocopier’s scan-to-PDF function if available.

MarkScanner prepares a rubric from your materials. Check, adjust, and approve it before the student work is marked.

Answers to the questions you ask after every test

What should I reteach next?

See which questions challenged the class, then look at the responses behind the results. Use that information to decide what needs another explanation or more practice.

How is this student progressing?

Revisit a student's previous work, grades, and feedback. Keep the evidence together so you can see their progress and prepare more targeted follow-up.

How do I get these marks into my records?

Export grades as a CSV spreadsheet to reduce retyping. Keep a digital copy of the work and feedback sheets for later reference.

Try it with your next quiz or test.

Meet Oscar

A local founder you can contact directly

I’m Oscar ONeill. I grew up in London, attended Lord Roberts, Central, and Beal, and graduated from Western University in 2017.

I’ve spent the past year building MarkScanner with direct input from Ontario secondary school teachers, focusing on everyday marking and feedback needs.

I’ll personally help you get your first assessment set up and be available by email, phone, or video call throughout your free month.

Want to walk through your first assessment together?

Email Oscar oscar@markscanner.ca (519) 914-5274

Call or text. Calls ring through weekdays, 10 am to 5 pm ET; otherwise leave a voicemail.

Questions before you try it?

What teachers ask first

Can I use tests and quizzes I've already made?
Yes. Upload a blank copy, worked solutions or an answer key, and scanned student work. You can also include a rubric or additional marking instructions.
Can it read messy handwriting?
MarkScanner is designed for handwritten math, including students' working. Handwriting and scan quality can affect the results. It can flag unclear or illegible answers for review, and you can check the original scan and correct the draft marks. An answer without a flag can still need correction.
Can I change how it awards marks?
Yes. Check and adjust the rubric before marking, then review and change the draft marks and feedback before returning results. You decide the final grades.
Do my students need accounts or computers?
No. Students complete their work on paper. You use MarkScanner to process and review the scans and prepare their feedback.
Do I need to upload every student's paper separately?
No. One PDF can contain the class set, along with your blank test and answer key or solutions.
When does my free month start?
On the start date you and Oscar agree once you get in touch. Reading this page or sending an email does not start it. You start when you are ready to mark an assessment.
Is a credit card required?
No. This invitation gives you one free month without a credit card, and you won't be charged automatically.
What happens after the free month?
Continuing with paid access is optional at $49 CAD/month plus HST. You would need to choose a paid subscription to continue. There is no automatic charge.
Can I share the invitation with colleagues?
Yes. Share this page and your invitation code with other math teachers. Each teacher emails Oscar, uses their own account, and starts their own free month. Sharing a code does not share access to your classes or student work.
What if I need help?
Contact Oscar at oscar@markscanner.ca, or call or text (519) 914-5274 (calls weekdays, 10 am to 5 pm ET). Personal setup help and support by email, phone, or video call are included throughout your free month.
