An AI exam grader marks a paper exam against the answer key, rubric, and mark scheme you already use. You upload the exam students sat and the marking documents that go with it. You photograph the scripts. Marks come back against those documents. You review them, adjust any mark before release, toggle the feedback students will see, and hand the exam back as a PDF or an email.
Graider is the AI red pen for paper grading, a product of DM Liquidity LLC. Teachers photograph the stack, grade on their own rubric and answer key, review and toggle feedback, and hand work back as a PDF or an email. You keep the pen. The public site is graider.org. The page for running an exam set is AI exam grading. This guide stays with the documents you prepare and the review you do before handback.
Your exam. Your mark scheme. Their scripts. You keep the pen.
Grade exams with AI once the marking documents are the ones you would defend in a department meeting. Three pieces usually sit in the folder, and each one has a job a second reader can follow.
The answer key holds the responses you accept: a final value, an equivalent form, a short-answer phrase, a diagram label. If two answers are both correct, both belong on the key. A common wrong answer can sit there too, with the mark it earns.
The rubric holds the marking language around that key: what a complete response includes, which method you will accept, which units count, and which mistakes you comment on every time. One course wants the method from the notes. Another accepts a different path when the reasoning is clear. Write the call you would explain when a student asks about a mark.
The mark scheme allocates the points across the parts. A six-mark problem might give two marks for the setup, three for the working, and one for the final value with units. The scheme is the map of the points. The key is the accepted content. The rubric is the language you use when a script lands between the rows.
An AI exam grader for teachers applies those three documents to the photographs of the scripts. A missing unit can draw the comment you already teach. A sound method with a slipped last step can receive the partial credit the scheme already names. Have these ready before you photograph the set:
If the rubric rows are still loose, write them so a second reader could point at the page for every point. That writing job has its own guide: how to write a rubric AI can follow. Bring the finished rows back to the exam. The mark scheme and the key still lead.
Write each partial-credit rule as a condition, the points, and a short example of a script that earns them. An AI exam grader applies a rule it can point at on the page. A rule you have not written down gets decided again on every script.
A method mark needs the work visible. Name the step: the correct setup can be one mark, the working that follows can be the next, and the final value with the unit from the question can be the last. An accuracy mark sits on the result. Say what still earns the method marks when the result is wrong.
When a student uses their own earlier number correctly in the next part, write whether that follow-through earns the later method marks, and write the other case in the same row. Put each accepted alternative method on the key with the marks it can earn. A missing or wrong unit can withhold the final mark and keep the method marks. You still open the page where the unit is ambiguous or the path mixes two methods.
Paper exams arrive as scripts: a single sheet, or a booklet with work on the back and a graph on a later leaf. Photograph every page a student used, in decent light, with the full sheet in the frame. Keep one student's pages together so part (a) stays with part (b). The photo habit for handwriting and the back of the page is in how to grade handwritten tests with AI. On an exam, the same habit covers every page the mark scheme might award.
The first pass applies your mark scheme across the photographed set. Review is where you keep the pen. The teacher has the final say. Open the scripts that need a teacher: a method you have not seen, a graph that carries the reasoning, a follow-through you want to judge in context, or a page too faint to trust.
Read the mark against the row that produced it. When your judgment and the first pass disagree, adjust the mark. The score you release is the one you choose. A right setup with a copied digit can keep the method mark and lose the accuracy mark, when that is what your scheme says. You make that call on the page. The adjusted mark is the one that goes home.
Feedback is a separate decision from the score. Toggle feedback on for the comments that should travel with the mark. Toggle feedback off when the mark is enough, or when you will say the note out loud in the next lesson. The PDF or the email goes out when you say so. If you adjusted the same kind of mark on many scripts, add that example to the scheme so the next exam already has the ordinary case written down.
When the marks you would defend are the marks on the page, share a marked PDF or email the results. Students see the exam after you approve it. Comments on, for the class that will read them. Comments off, for the class that will go over the paper together. You keep the pen until the PDF or the email goes out.
An AI exam grader marks photographed paper exams against the answer key, rubric, and mark scheme you provide. With Graider, you upload those documents, photograph the scripts, review and adjust the marks, toggle feedback, and hand the exam back as a PDF or an email.
Prepare the exam students sat, the answer key of responses you accept, the rubric language you use in the margin, and a mark scheme that splits points across method, accuracy, units, or other features you score. Each partial-credit rule needs a condition, a point value, and a short example.
Yes. Write the condition and the points, including follow-through from an earlier part when you allow it. Graider marks the photographed scripts against that scheme. You review and adjust any mark before a score goes home.
Open the script, compare the mark to the row on your scheme, and change the score when your judgment and the first pass disagree. Toggle feedback on or off, then release a PDF or an email when you can explain the marks. You keep the pen.
