An AI test checker for teachers compares a photographed class set with the answer key you wrote for that test. Students have already filled the page: a letter in a bubble, a phrase in a blank, a few lines of working under a problem. Graider marks those written answers against your own key. You review those marks before a paper goes home.
You upload the test and the answer key. You photograph the stack. Marks land against your own rubric and key. You review and override, toggle feedback, and keep the pen. Then you hand the work back as a PDF or an email.

Your key. Their papers. You check every mark. You keep the pen.
Checking tests against an answer key means reading each mark against the row that produced it. The first pass has applied the key. You decide whether that mark matches the call you would make with a red pen in your hand.
Use the same order on every paper:
How to lay the key out, with the accepted response and the points printed on the paper, is in AI test grader. Confirm the roster match so each checked test stays with the student who wrote it.
Start with the items your answer key already names. Each row shows the item number, the response you accept, and the points that response earns. On the photograph, read the student answer beside that row.
Compare the letter, the phrase, or the number with that row. When they agree, the mark can stand. When they disagree, open the page and choose the score you will hand back. If one letter is circled and a second letter sits in the margin, decide which one stands. When several papers do the same thing, add that rule to the key.
Some items follow a fixed list of responses. Others earn points in pieces, from a rubric row for method, evidence, or working. Answer key grading vs rubric walks through which document should drive each kind of item. Use the document you uploaded for that item.
A second correct choice, a synonym you already count, or a method you teach beside the first one belongs on the key. If three phrasings earn full credit in your class, list all three on the row, with the points.
During the check, look for a correct answer the key still needs. A class often settles on one extra wording together: a plain-language phrase for a technical term, a second date format, or a second formula that reaches the same value. When you would give that wording full credit with a red pen, add it to the key and override the marks that missed it. When you would give it part of the points, write those points on the row and apply that decision across the set.
A near miss can sit on the same row, with the points it earns and the comment you already write in the margin. Spelling on a technical term, a missing unit, and a response that answers the neighboring question are calls you already make.
Partial credit is a decision you already make, written where the first pass can follow it. The setup earns its points, the working earns the next part, and the final value with the unit earns the rest. A common wrong answer can earn some of the points, with the comment you already use for that mistake.
Open a paper where the working is right and the last line is wrong. Confirm the points match the split you wrote. Open a paper where an earlier number is wrong and the later lines follow that number correctly. Apply the follow-through rule you put on the key. Where two methods are mixed, or the writing runs into the margin in a way the key did not cover, set the mark yourself.
The check against the key covers the written answers on the page: choices, short phrases, and worked lines. Some tests also include a labeled diagram, a graph, or another drawing. Open that drawing at review and set the score yourself. Diagrams, graphs, and drawings are yours to mark. You keep the pen on that call.
A faint pencil line, a rewritten letter, or a word in the margin can carry a Low confidence badge, the flag on hard-to-read handwriting.
Start this part of the check with those badges. Read the line on the photograph. Compare it with the row on your key. When the answer matches a response you accept, keep the mark at the points that row earns. When the line is still hard to read, set the score you would give after looking at the page yourself. Override any score you disagree with.
A page that is too dark, cropped, or blurred is worth another photograph before you rely on the mark. The badge tells you where the handwriting needs a teacher first. The score students see is the score you kept.
Keeping the pen means your key stays the source of truth, and the score on the paper is the one you release. Override a mark when your judgment and the first pass disagree. Change the points. Edit the comment so it matches the note you would write in the margin, in your own words.
Toggle feedback on or off for each paper. Turn comments on when they should go home with the score. Leave them off when the class will talk through that item and the score is enough for the handback. The words a student reads are the words you kept.
After the check, hand each test back as a PDF or an email. One PDF per student holds the pages they wrote, the score you kept, and the comments you turned on. Email that file, or return the PDF through the path your school already uses. You keep the pen.
An AI test checker for teachers compares photographed paper tests with the answer key you uploaded. Graider marks the stack against that key. You review each mark, override a score when your judgment differs, toggle feedback, keep the pen, and hand the tests back as a PDF or an email.
Read each student answer next to the row the key covers. Confirm alternate correct answers and the partial credit you already give. Open every Low confidence badge, and override any mark you would explain differently before the paper goes home.
The Low confidence badge is the flag on a hard-to-read answer. Open the photograph, compare the line with your key, and override the score when the page and the first pass disagree.
Yes. Override the points, edit the comment in your own words, and toggle feedback on or off for that paper. You keep the pen. Students see the score and the comments you kept when you hand the test back as a PDF or an email.
