Answer key grading is the choice of which document decides the points. A fixed answer key lists the responses you accept and the points each one earns. A rubric lists the qualities you score, with levels, points, and a short example. Some papers need the key. Some need the rubric. A mixed paper needs both, with one document owning each item.
Graider is the AI red pen for paper grading, a product of DM Liquidity LLC. Teachers upload the test and their answer key or rubric, photograph the stack of student papers, and Graider marks against those documents. You review the marks, toggle and edit feedback, and keep the final say. Graded work goes back as a PDF or an email. Everyday paper tests run through AI test grading.
Your key. Their papers. You review every mark. You keep the pen.
A fixed answer key is the right driver when you can list the accepted response before anyone sits down. Multiple choice, short factual answers, and math final answers sit in that group.
For multiple choice, write the letter or option text that earns the point. When two options are both acceptable, write both and the points each one earns.
For a short factual answer, put the word, name, date, formula, or phrase on the key, plus every equivalent you will count: a full name and a short form, a date written two ways, a unit as a word or a symbol.
For a math final answer, write the value, the equivalent forms, and the unit when the unit is part of the mark. If you would award both a decimal and a matching fraction, both belong on the key.
Hand the key to a colleague with a photograph. On the ordinary cases, they should award the same points you would. Method marks, the points for a valid path, are covered below and on AI math grading.
A rubric is the right driver when you score the quality of a response. Essays, extended response, method marks, and lab write-ups sit in that group. Rubric AI grading means the levels you wrote are what the marks follow.
On an essay, name the criteria you already use: claim, evidence, explanation, organization, and conventions. Each one has levels, points, and a one-line example a second reader can find. Extended response uses the same shape. If a history question asks for a cause and two documents, say what a full explanation includes, what a partial explanation includes, and the points for each. The prompt stays on the test. The scoring stays on the rubric.
Method marks are points for a valid path, including a path that stops short of the final value on the key. Name the method, the points, and a short example. If a slip in part (a) may carry into part (b), write the condition and the points. One document owns that point.
A lab write-up gets a row for the data table, the graph, the sources of error, and the conclusion. A single calculated answer can stay on the key. The write-up stays on the rubric. See how to write a rubric AI can follow.
Section A can be selected response and short answers. Section B can be the essay, the multi-step problem, or the lab question. Answer key vs rubric, on that paper, is a section choice.
Put the answer key on section A, with the accepted response and the points. Partial credit is a second line: the partial response, and the points it earns. Two points for the correct cause, and one point for a related cause that leaves out the document, is a line a second reader can apply.
Put the rubric on section B. Partial credit there is a middle level between a full response and a missing one, such as one piece of evidence with the explanation unfinished.
On a math paper, the final value can sit on the key and the method marks on a short rubric. AI grading with an answer key uses the rubric on the items you scored with levels. Upload both. If section A is 20 points and section B is 30, the paper is 50, and the rows in each section should add up.
Write both documents before the first student writes, in the words you already use when you mark. A second reader with the documents and a photograph should award the ordinary cases the same way you would.
Give each scored point on the key its own row: the item, the response, any equivalent, and the points. If a missing unit changes the score, state both point values. Give each rubric criterion its own row: the levels, the points, and one example. Two classes sitting the same paper share one key and one rubric.
Add a line anywhere you would have to stop and ask what you meant. If you change a line after you start, write it down, then pass back through the scripts you have already opened.
Upload the test, the answer key, and the rubric. Photograph every page, with even light and the full sheet in the frame. Graider marks the photographs against the documents you uploaded.
You review every mark before anything goes home. Compare each score to your key or rubric, and override any mark you disagree with. You keep the pen on that override. Toggle feedback on when the comment should go home, and off when you will teach the item in class. Edit a comment so it sounds like you.
If a response you accept was missing from the key, add it, then look again at the scripts you already opened. Hand each paper back as a PDF or an email after you send it. The score a student sees is the one you kept.
Answer key grading means the marks follow a fixed list of responses you accept, with the points for each. You upload that key with the test. Graider marks the photographs against it. You review every mark and keep the pen.
Use a fixed answer key for multiple choice, short factual answers, and math final answers. Write every equivalent you accept on the same row, with the points it earns.
Use a rubric for essays, extended response, method marks, and lab write-ups. Each criterion needs levels, points, and a short example a second reader can find on the page.
Yes. Put the answer key on section A and the rubric on section B. Partial credit is a second line on the key, or a middle level on the rubric. Upload both, and review every mark before handback.
You compare each score to your key or rubric, override any mark you disagree with, and toggle or edit feedback. Graded work goes back as a PDF or an email after you send it. You keep the pen.
Read the scores, toggle feedback on or off, and keep the pen on any override. Hand each paper back as a PDF or an email.
